What happens to planetary nebulae and supernova remnants after they are ejected into space?
Once ejected supernova remnants are formed such as the crab nebula
Are there any high mass stars that currently pose a threat to earth?
Yes the star IK Pegasi B
Why does double shell burning never reach equilibrium?
the shells do not burn at the same rate, the helium shell becomes thermally unstable and goes through periodic thermal pulses
Approximately how big is a supernova explosion?
They can eject matter into space from anywehre between 9000 to 25000 miles per second
Why does iron begin to build up in high mass stars?
