Smile New Theory on How Massive Stars Shine

Very interesting article at Astronomy.com about how massive stars near the ends of their lives may avoid the nasty problem of disappearing down the gravity plughole

Thanks, interesting.
So does that mean that a star can be reignited ?
I assume they conclude only giant stars when collapsing can reach the needed temperatures and density?

Seems to be the case....the star goes through the usual steps, but it seems when its core gets to nuclear densities, the temps reach such a degree that the quarks in the matter of the core begin to generate energy and keep the star from collapsing further.

Yes, only massive stars seem to undergo this.

This immediately reminded me of the movie "Sunshine"
