Red giant is the largest and the brightest.
Main-sequence,red giant,white dwarf.
a red giant
It is when the star is close to its death stage. {Main Sequence, Giant, Super Giant, and then the white dwarfs}
protostar, main sequence, giant, nebula, white dwarf & black dwarf.
nebula then protosar then red dwarf, yellow star or a blue giant then a red giant then a red super giant then eithr a white dwarf or a supernova from the supernova a black hole or a neutron star if it is a white dwarf it turns into a black dwarf then a black holeNebulaBaby starStarGiant or supergiantWhite dwarfBlack dwarf
No. Sirius is a two-star system consisting of a white main sequence star and a white dwarf.
Right now the sun is a main sequence star. When it uses up the hydrogen in its core it will become a red giant then shed its outer layers to become a white dwarf.
Yes. The possible cycle is: protostar/brown dwarf main sequence star red giant supernova/super giant white dwarf/black hole black dwarf
None of those is a main sequence star.
A star with a low mass will go through these stages: 1. Protostar nebula 2. Main sequence (as a red dwarf) 3. Red giant 4. Planetary nebula 5. White dwarf (6. Black dwarf is theorized to occur after white dwarf)

No, white dwarfs are cooler than supergiants, they also have a lower luminosity (are more faint). A different viewpoint: There's obviously a range of temperatures for these stars, but the hottest (surface temperature) known star is in fact a white dwarf. It has a surface temperature of over 200,000 degrees Celsius.
