Only heard about this recently, a star that didn't expand into it's solar system when it "died", what are the mechanics of that?

Thanks so far, but i am talking about a star recently in the news that neither contracted or expanded from what i was told. If it's true, this is bizarre.

i dont see how this is possible. its possible for a star to not expand i guess if it doesnt have enough mass to fuse helium. but if a star runs out of hydrogen to fuse then its no longer creating presure to counter act the gravity, so it would have to contract, i do not see any other thing that could happen.
is it possible that you heard wrong and it was just a brown dwarf, or a failed star.

Depending on the size of the star is what happens with the star.....but mostly once stars run out of hydrogen to burn, it needs a higher temp to burn the next source helium...so it starts to shrink and increase its temperature

it doesn't expand because the energy of the star already died off or chancesit can blow the whole universe

I wish you had a link.If true,it is more than bizarre,it would shake the foundation of everything we thought we knew of stellar life.

A star large enough to burn hydrogen,
but too small to burn helium will simply
cool and shrink.

some stars collapse in on theirselves when they die, thus forming a black hole
