Question

What would happen to our sun during its lifetime, compared to a star 10 times more massive?

Answer 1

Once our sun runs out of hydrogen to fuse into helium it will begin to expand and fuse helium, during this time it will grow to a red giant becoming cooler but many times as large consuming both Mercury and Venus and possibly the Earth.  It will then expel all the gas around it leaving behind its core as a white dwarf and planetary nebula.  The expulsion will be a nova class explosion.  a 10 Solar Mass star will behave similarly except it will explode as a supernova and may have enough mass to then collapse into a neutron star (the core of a star made up entirely of neutrons)
