Magnetospheric eternally collapsing objects

[tovisonnenberg]

I read about a theory (https://en.wikipedia.org/wiki/Magnetospheric_eternally_collapsing_object) (https://arxiv.org/pdf/astro-ph/0602453.pdf) that proposes that collapsing massive stars never actually form a singularity, and instead they end up as "magnetospheric eternally collapsing objects" (MECOs). The theory states that as the infalling matter from a collapsing massive star grows denser and hotter, there will be enough radiation for the object to approach the Eddington limit and halt the collapse. The object is then said to be in "eternal collapse".
My question is:
How can this object maintain its stability for eternity? Why wouldn't the object eventually radiate itself away? At least some radiation from the object must escape because the theory explicitly states that MECOs do not form event horizons.

hi there

I read about a theory

where ?
Please don't say something like that without links, quotes etc, so that it can be evaluated by those you would like to read and comment on your post
We don't know if you were reading a valid scientific paper or some poorly written, for the masses, pop-science article ?regards

I added 2 links in the original post. Thanks for letting me know!

The Wiki article seems to claim that the mass would indeed radiate away.

I’m afraid I don’t see how radiation pressure prevents an event horizon from forming, especially in the case of supermassive black holes. The Schwarzschild Radius for these is, in some cases, greater than the diameter of our Solar system. Radiation pressure in this case would have to keep multiple individual stars outside of that radius.

I have not, however, examined the mathematical treatment presented, so maybe I will have a better understanding later.
