What's the stats on the sun after it blows up?

Question

Into a red giant. It's new temperature, luminosity, radius, spectral class and mass.

I'm asking because sometimes a few tenths of a solar mass in weight difference can make a big difference in result.

Like the mass difference between
main-sequence F and K stars is very little.

Numbers please.. if I wanted all that I'd just look at a Hertzsprung-Russel diagram and guess.

Answer 1

White Dwarf!!

After such the sun has become a red giant during its helium-burning phase, it will shed its outer layers to form a planetary nebula, leaving behind an inert core consisting mostly of carbon and oxygen.

A white dwarf is an astronomical object which is produced when a star of low or medium mass dies. These stars are not massive enough to generate the core temperatures required to fuse carbon in nucleosynthesis reactions.

Eventually, over hundreds of billions of years, white dwarfs will cool to temperatures at which they are no longer visible. However, over the universe's lifetime to the present (about 13.7 billion years) even the oldest white dwarfs still radiate at temperatures of a few thousand kelvins.

Answer 2

the sun will not blow up. It is a yellow sun, in about 5 billion years it will expand to become a red giant, burning helium. It will consume Mercury, Venus, Earth, and possibly Mars. After it has been a red giant, it will shrink into a white dwarf star, and will eventually fade into a brown dwarf, leaving the solar system a cold and dark place. If humanity has survived, we will either have made Jupiter a star or found a way to go to a different system.
