Red Dwarfs are cool small stars and there temperature (on the surface) is around 5840 degrees Fahrenheit or 3210 degrees Celsius.

How does a stars temperature change as the star ages from main sequence star to a red giant and from a red giant to a white 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.
What is the temperature of the core of a neutron star?
Depends on the age of the neutron star. As a neutron star no longer has any method to produce heat, it will slowly cool over time. A young neutron star will have a core temperature of about 106 kelvin.
What happens to the temp of stars as a star changes blue to red?

What is a small star that only gives of faint light and are cool?
That can either be an old white dwarf, a red dwarf. or a brown dwarf.
You know the white dwarf stars Sirius B has a mass comparable to the Sun because of?
Because a white dwarf star is the core leftover from a bigger star and the core is the densest part of the star so although the star is smaller than the sun it has a similar mass as it is more dense

What is the temperature of a white dwarf star?
A white dwarf star's temperature can range from approximately 7000K to 19000K.
The star that is the red and the cool?
A Dwarf
Is betelgeuse hotter than a white dwarf?
No, the surface temperature of Betelgeuse is colder than the temperature of a white dwarf, the white dwarf is the hot core of a dead star. Also, red stars are always colder than white stars.
How are giant stars and white dwarf related?
A giant star is a dying star that expanded, and the core shrinks are the same time. When the shell of the giant star drift into space as planetary nebula, the core became a white dwarf. The white dwarf is made from the core of the giant star.
What makes dwarf stars and giant stars hot or cold?
Basically, the amount of hydrogen (mass). The more mass a star has, the greater the pressure in the core. The greater the pressures in the core, the higher the temperature, the higher the temperature, the hotter the star will be, the hotter the star, the blighter the envelope will be.
How does a star turn into a white dwarf star?
A white dwarf is what stars like the Sun become after they have exhausted their nuclear fuel. Near the end of its nuclear burning stage, this type of star expels most of its outer material, creating a planetary nebula. Only the hot core of the star remains. This core becomes a very hot white dwarf, with a temperature exceeding 100,000 kelvin.
What type of temperature of the star if it is red?
Low temperature because red giants are star with low temperatures, but very bright. A star forms when a portion of a dense interstellar cloud of hydrogen and dust grains collapses from its own gravity. As the cloud condenses, its density and internal temperature increase until it is hot enough to trigger nuclear fusion in its core (if not, it becomes a brown dwarf). After hydrogen is exhausted in the core from nuclear burning, the core shrinks and heats up while the star's outer layers expand significantly and cool, and the star becomes a red giant.
How a star becames a white dwarf?
A white dwarf is the core of a dead star. As the star runs out of fuel, it expands into a red giant, as the shell of the red giant became a planetary nebula, and the core shrinks and became a white dwarf.
What is the temperature of super giant star?
the temperature of..an white dwarf star is 10,000
