How does the surface temperature of a white dwarfs compareto a white main sequence star?

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.

∙ 13y agoA star on the "main sequence" is a period in a stars stellar evolution, whereas a white dwarf is a stellar remnant.
A star on the "main sequence" is any star fusing hydrogen into helium, so size doesn't come into it.

A red giant can be 10 to a 100 times larger than our Sun, whereas a blue supergiant is generally only about 25 times larger than our Sun.

∙ 13y agoA newly formed white dwarf has a much higher temperature that a red giant, however, because the white dwarf, has no means of maintaining that temperature, it will slowly cool until it is cooler than a red giant.

A main sequence star is a star a white dwarf is degenerate matter.
A main sequence star controls it's heat a white dwarf doesn't.
A main sequence star is a gaseous ball a white dwarf is a compact body of degenerate matter.

A main sequence star is huge, whereas a white dwarf is about the size of the Earth.
Wiki User
∙ 15y agoYes a red giant is hotter than a white dwarf. A white dwarf has burned most or all of it's hydrogen and stays lit due to residual heat.
Wiki User
∙ 14y agoNo, they start out cooler than the sun and will get progressively cooler over time.
Wiki User
∙ 13y agoBlue giant. Hotter stars are blue - white, cooler stars are red.

∙ 10y agoNo. A white dwarf is much smaller than a main sequence star. Some are about the same size as Earth.

What classification of stars has the lowest surface temperature?
Black dwarfs have the lowest surface temperature.
Why are there no white dwarfs among the 100 brightest stars?
White dwarfs have very small surface areas compared to main sequence stars and therefore cannot emit as much light.
Which types of stars is considered part of the main sequence?
Red Dwarfs.
What type of star is most likely to be found on the main sequence?
The curve that contains most stars is called the "Main sequence". The stars on that curve are known as "main sequence stars". Their main characteristic is that they get their energy from fusing hydrogen-1 into helium-4.
What is the average temperature for a white dwarf star?
From the Wikipedia article: "Most observed white dwarfs have relatively high surface temperatures, between 8,000 K and 40,000 K"

Black dwarfs have the lowest surface temperature.

Is the surface temperature of white dwarfs higher or lower than red super giants?
Yes dwarf has higher temperature
Are main sequence stars older than white dwarfs?
no
What percent of the stars are considered part of the main sequence?
Red Dwarfs
Which types of stars is considered part of the main sequence?
Red Dwarfs.
Describe two types of stars that are not on the main sequence-?

What is a white dwarfs temperature?
it's cool
Giants supergiants white dwarfs have left the main sequence?
Yes, all those types of stars have left the main sequence.
What is the name for older stars?
"Main sequence" stars are no longer new, and are just cookin' along for millions of years. "Main sequence" stars, depending on their weight and whether they orbit another nearby star can get old and become red dwarfs, white dwarfs, black dwarfs, neutron stars, novas, or super-novas.
