Super Massive Brown Dwarfs That Should Be Stars But Aren't

Just an idea, could they be formed like planets and thus have a rocky core like the gas giants?

Like the universe cares about sticking to our narrow minded classifications . It does what it wants rules be damned

So people smarter than me got something wrong? Sorry, I can't accept that.

About Luhmann and lithium THese are well below the lithium burning limit. So they should show us lithium which is what the test is all about. The problem is with brown dwarfs like those discussed here: the usual visible lithium in brown dwarfs is no longer there so it has become even more difficult to assure they are either a brown dwarf or a red dwarf. At least that is what I learned.
Another point is the temperature of these ultra massive brown dwarfs. At some point (an object with 90 MJ which was found a few years ago) brown dwarfs enter a fase of unsteady hydrogen fusion. The 90 MJ has remained near M-class with 2350 K temperature being no less than 10 billion years old. Still it is classified as a brown dwarf and not a red dwarf. So that to me at least is even more interesting with probably the brown dwarfs mentioned here too: they very likely are still fusing hydrogen in an unsteayd manner. So how does that translate into their sizes.
It is pretty certain that the brown dwarfs very close to the divide between brown dwarf - red dwarfs remain very hot and very star like for billions of years.

So pretty much Brown giants?, Stuff like this makes It more likely there could Neptune sized earths with surface gravity of our planet. Hell Hyper earths are better term for Uranus & Neptune since when smaller or have 90% of there gas blown away they look like weird water worlds?.

Massive brown dwarf ,Probably Dead star or Doesn’t have a enough gas to become a star

And one of the best facts about brown dwarfs, is that brown dwarfs could be a missing link of how red dwarfs are formed,
And why I say(text)this is because of how red dwarfs take a long time to use up their hydrogen fuel(up to ten or more trillion years),
And this can create a problem of how they form?
And this slow star formation is called the sloth formation paradox (you can tell this has something to do with the speed of star formation),
And this simple(actually complicated) math formula is about lifespan equals formation rate,
It’s state that the more mass the star has, that the more gravity it has, and is why high mass stars form much faster than low mass stars(including our sun).
And this is why high mass stars live faster than low mass stars, it’s because of gravity pushing their much more ferociously than low mass stars,
and this in turn makes the use up their hydrogen fuel much faster.
And that’s why It’s a problem for red dwarfs, because it can hundreds or even thousands of times longer to make a red dwarf than it is to make sun like stars,
And it’s important for to form much faster or else some incredibly violent event disrupts the formation of a red dwarf,
And that’s why I think brown dwarfs are the solution to the sloth formation paradox, and it’s by brown dwarfs colliding with each other,
and this in turn forms red dwarfs much faster,than it takes for a nebula to form them,
And brown dwarfs can form very quickly (almost as quickly as high mass stars(and in case you are wondering how long it takes to form a high mass star, it’s between thousands or hundreds of thousands of years to make high mass stars)and brown dwarfs takes between a hundred thousand/ a hundred million years to form brown dwarfs),
And I recommend more than two brown dwarfs to create a red dwarf.

Excelent, Anton!

A rainbow pretty much explains how the universe works, everything is just a smooth continues transition. You can call part yellow, but where does it begin and end?

Maybe they're just Shy...🙄👋😬

It’s gotta be a combination of mass and composition. I also think that we need to study fusion a lot more, because there seems to be an un-understood reaction path going on. Which could also tie into the fact that most hyper giant stars are metal poor, while most smaller stars are metal rich. I don’t think that it’s just an effect of age, or more precisely its like we’re saying “A” causes “D”, when in reality “A” causes “B” which causes “C” which interacts with “A” or “B” to cause “D”.

They are currently off the circuit. Imagine a fluorescent light with no power

Iron rain?! Thats pretty metal....

'Brown dwarf' sounds a bit too politicaly correct.

Super massive brown dwarf is an oxymoron like jumbo shrimp.

So are there any starts that shouldn't be? The opposite of what is talked about in this video, stars that shouldn't have activated with a mass that low?

I'm sure Elon would love to get his hands on a lithium star 🌟

Seriously tho.. May be they are stars.. But they're young and the light hasn't made it across space to Earth yet. All we see is the massive ball of dense gas before fission/fusion started? Just a wild guess

Maybe they just need someone to give them a light. 😂🔆😛

I recall a scheme to transform Saturn into a Star.

Don't scare me like that, I thought I wasn't going to get my "Hello wonderful person".

What's the possibility of a brown dwarf from turning into a planet when it gets older?

In a comparison to the universe and my personal analogy:
"We are but grains of sand upon the beach in a universe of endless possibilities".

I would like a question answered. How big can a solid object get (say a sphere of pure gold, or of platinum, or of uranium, or of pure carbon or pure silicon) before it collapses directly into a black hole? *Could there be a supersized rock (the size of a star) on the verge of sudden collapse into a singularity?

You should try to avoid the teem "burning" for fusion as there are people that would be confused. I've actually had people who honestly asked me "How does the Sun burn when there's no air in space?". Despite these people being obviously unversed in science, they are still seeking to learn so we should try to avoid confusing them more than necessary.

Long since, I got frustrated with classifications, for the same reasons that are shown in this video. Some classes obey well-defined criteria. Good. But the remainder may be left undefined, unless the criterium becomes a series of negations: neither this nor that nor that other..... et cetera. So that you end up with a bad class with whatever objects happen to not meet any of the other classes' criteria.
For the above reason, I rather use independent criteria. For each of these criteria, a type of things emerges. Some things meet several criteria, and therefore they are several types each. Why should overlapping types be worse than classes, which never overlap?
The main reason for classifications is to have something definite to do with each and every class that does not interfere with what should be done with any other class. But when such an interference can be avoided by other means, such as precedence of actions, or when it does not matter, typification may be easier and preferable. It usually requires less parameters for every criterium, this is the reason why typifying criteria generally are independent of each other.

Super massive dwarves = world's tallest midgets ???

Is hydrogen burning suppressed in a rocky core?

I’m a massive brown dwarf who should have been a star too!

"A Super massive brown dwarf" is also a different way of just saying "a black dude" haha 😄 😆 🤣 😜 😂 😅

My guess would be it's a matter of composition. If they're all orbiting proper stars maybe they're planets with a planetary composition i.e. their cores are full of heavier elements rather than hydrogen and at the depth where hydrogen starts to predominate the pressure is only enough to burn deuterium.

Is it possible for other external factors and conditions that influence when or if a 'brown dwarf' begins fusion and hyrdogen burning, that are independent of the object's mass itself?

EDIT: I posted this before I got to the potential gravitational influence part

Nature breaks nothing of course, other than the human mind perhaps.

Did they consider the composition of the core? Could there be a rocky core for these Brown Dwarfs, adding mass and preventing normal star activity?

You, YOU are a wonderful person!

You aren't talking about exceptions to the rule, we simply are clueless what the rules are. These objects are following the rules just fine.

Hello wonderful Anton. This is person. Thank you for being you. Can you go a little more in depth on molten salt thorium reactors soon?

perhaps have too many other elements than hydrogen . Not enough hydrogen mass for fusion.

I'd bet you a can of coke they just swallowed up an iron heavy planet sized object that just settled to the center and inhibited stellar fusion. We've seen star systems with fast orbitals that we previously thought impossible, so why not an iron heavy object, slowly dragged down by the accreting stellar cloud or knocked inside by a collision with another body.

Probably later generation objects, so there are more elements than hydrogen to compose its mass. If there's enough of some element or other heavier than hydrogen, it's probably acting as a "neutron poison". (Helium-3, or even boron?) That is it absorbs particles that prevent a chain reaction. Thus hydrogen fusion can't take place to full effect, and the object is still below the threshold to fuse heavier elements. Even though it's big enough to form a proper star, it remains a brown dwarf because there is material that interrupts the fusion process in regards to the mass that does exist.

At least it seems like something that would make sense, not sure if that's the case. Is there enough energy to get a read on it's element make-up via spectral analysis?

So if stars burn lithium and brown dwarfs not always I'd be interested to know what star types burn which metals? Is there a table available? Edit: I'll look, I'm not that lazy 😂

so many exceptions to wrongheaded standard model hypotheses, it's almost as if some of our basic understandings of astrophysics and cosmology are incorrect or something ... thanks for your work Dr; may you live to see many great revolutions in science

So much of what's unknown is always difficult to classify. But we do need to always pursue objective classifications with current data in order to discuss and improve.

i always thought a brown dwarf IS a star.

Just like the cave in earth with a sooner have live.
If the brouwn dwarf is inside the same situation as the space it is within it did not become active had.
You see wat it burns (on demand of the external inviormend)
Not the other way arond🙏

En yes if I tace this in release it in a more negative space it has to release en start exnighting🌈
Same as how a photon just happence to intangle with the communication in the strinks of the light we interact with trouth beïng part of 😍😋🌐

Slowely we wake up 💖🙏💖

We are going to be surprised how many brown and red dwarfs JWST exposes.. Way more than we expected
The infra red sensor will be game changing

I have to finish my dark matter report b4 JWST
Sends back 1st data pack.. I can only say that JWST will either prove or disprove my theory.. But I feel that the data i expect to come back will provide an explanation and proof of dark matters mysteries

The fusion within a star may be dependent also on the rate at which its mass accumulated.
