Binary Stars and Supernovas

Question

I wonder, what happens, if you have a huge O class star and lets say a class M Star in the same System and the other Star explodes. Would it destroy the red dwarf or would it change spekral clall?

Answer 1

It would depend on the distance.  Orbits can be arbitrarily large. The m dwarf could be disrupted, could gain or lose a bit of mass, or be essentially unchanged.

The fact that planets have been discovered orbiting a pulsar (neutron star) does not necessarily suggest that planets survived a supernova.  It's possible that they formed from the debris from the supernova.  It's hard to prove though.

Answer 2

I think that no one is really sure yet.

You'd think that the nova would destroy the other star, but we see all sorts of weird stars out there, like living stars orbiting black holes, or one star apparently surviving a huge nova explosion.

Answer 3

I would say there are too many variables to make an "educated" guess
