Well i really think its quite obvious. The fact that you asked this question in the first place must be an indication of your level intelligence. Obviously the stars internal temperature must rise at least 1200 Kalvin's before any sort of classifcation can be changed. The number of Kalvin's increased is a direct indicator as to how said star can be properly classified. So because of this a star's temperature must increase and exponential amount before anything should be changed.
OK, you explained the answer well, but might I say, you shouldn't be questioning anybodies intelligence! I am in AIG at my school, but hey I didn't know the answer to this! Anyway its intelligence level, not level intelligence, and your questioning their intelligence, really! Your atrociously bad spelling and grammar is also unbelievable!
Main-sequence,red giant,white dwarf.
Yes. The possible cycle is: protostar/brown dwarf main sequence star red giant supernova/super giant white dwarf/black hole black dwarf
A regular stars temperature cools as it balloons into a red giant. The color shift is evident by the word red because red is the coolest color of heat. The surface of a dying star is cool because it is so much farther away from the core than when it is on the main sequence. After a star sheds its 'skin' the only thing that is left is the white hot core, which will eventually dim to a brown dwarf which is nothing but the cool charred remains of the white dwarf and will give off little to no light.
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
protostar, main sequence, giant, nebula, white dwarf & black dwarf.
a red giant
Red giant is the largest and the brightest.
the temperature of..an white dwarf star is 10,000
dwarf stars,giant stars,main sequence stars
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.
A red main sequence star would be a red dwarf or a branch red giant. To be on the main sequence, you have to have hydrogen nuclear fusion.
It is when the star is close to its death stage. {Main Sequence, Giant, Super Giant, and then the white dwarfs}
