i answered this earlier, it's #4. <br />
When the reaction loses it's push against gravity, the element Iron si created, it starts a very fast chain reaction that collapses the star into the white dwarf. but a red giant chase usually will preceed the collapse. effectively swallowing out to mars. The effects on jupiter will be interesting.<br />
Our sun is far far too small to become a neutron star pulsar or black hole. it would need 8-20 times the mass to even have a chance.
white dwarf stars the reason who i say that is when i see the sun i don,t see yellow i see white.
various stars turn into any one of those 4 things, just depends mostly on the size of the star.
