R136a1, But about 5 million years older.

Описание
R136a1is a Wolf-Rayet star located 163,000 light years from Earth, in the Large Magellanic Cloud. It is the most massive star we have found, at 315 solar masses. When it dies, it will expand to an enormous size, smashing through the 23.4 AU upper size limit for a star, at 24.8 AU. The reason for this is that R136a1 breaks the rules on how massive a star can be. It was most likely formed via a stellar collision by 2 high mass stars.

The Upper size limit to a star is something I chose based on some of the largest stars volumetrically (Like Stephenson 2-18) and the mass limit to a star (200-300 M). Because of the Eddington limit, it is possible such a star like this is something that cannot exist in the physical universe, as very massive stars (such as R136a1) are extremely unstable, and undergo huge mass loss. If the star were any more massive it would not be able to achieve hydrostatic equilibrium, so basically the enormous radiation pressure would outweigh the gravitational force ,and rip the star apart. To sum it up, this is just an estimate on how big it could be *theoretically*.

Just a question: Where did you get the 23.4 AU upper size limit from?

NOTE: The Future size of R136a1 is not as shown in the thumbnail! It should be half the size due to my error of putting the diameter as the radius. Yes, it took me over 1 year to discover this error.
