Did red dwarf stars get that name because they burn the hottest of all stars?

No, red dwarfs are called such because of their reddish color. They are the coolest of the main sequence stars. Blue stars are the hottest.

Why does a red dwarf emit no light?
Color from a "black box" (i.e., a ball of gas with no intrinsic color) is a function of it's temperature. Much like heating a piece of steel in a fire - first it glows red, then yellow, then white, then blueish. So the answer is that they're cooler than the sun.
Can you touch stars in outer space?
It is possible but you need to be quick and the stars can burn you because they are mini suns
What Stars burn hydrogen?
All stars 'burn' hydrogen
Why do stars live so long?
Because they have huge amounts of fuel to burn out.
If the sun is so hot why doesn't it burn blue of purple?
The sun is catagorized as a "yellow star" This is also known as an intermediate star. Blue stars are the hottest. The Sun is not a blue star. - Em
What does a red dwarf sun burn?
Like all main sequence stars, a red dwarf is powered by the fusion of hydrogen into helium.
What kind of stars last the longest?
Stars that burn cooler and dimmer use less fuel, and so will last longer before they go out. smaller stars are generally more stable than larger ones, and so usually last longer because they contract into dwarf stars instead of going supernova. going with those assumptions, the longest-burning star would be a red dwarf star.
What does a black dwarf burn?
A black dwarf does not burn anything. A black dwarf is the cooled remnant of a dead star.
Can stars die?
yes because it can burn out
How many Red Dwarf stars do astronomers estimate have burnt out since the beginning of the universe?
Basically, none. Red dwarf stars have a lifetime that is much larger than the age of the Universe.Actually, if a lot of additional mass falls on a red dwarf star, it would start to burn more quickly. But then, of course, it would no longer be a red dwarf star.
What particles burn the hottest?
What burns the hottest carbon hydrogen or oxygen
The coolest stars in the sky are in color?
they can be a vary of different colours been as though stars are suns and no sun is the same so a shooting star could be knock out of orbit and super nova p.s what orbit you ask I'm talking about the galaxies orbit around the center of the universe and as the universe is so big we will never know were the center is.

How do stars get their colours?
The color is dependent on the mass of the star. Stars forming with more mass burn hotter because they must generate more heat to overcome the crushing force of gravity. Giant stars are blue/white in color because they burn so hot. The color spectrum is the ROY G BIV deal we all learn in elementary school. Blue light is the most energetic, with the shortest wavelengths, so hot stars burn blue/white. Our sun is a moderate, smaller star and burns cooler in the yellow spectrum, and small dwarf stars burn coolest, in the red spectrum. Age pays a role in the color too, because as older stars begin to run out of fuel, their outer layers puff outwards due to contraction of the core, causing the core to heat up for a time as it furiously burns its remaining hydrogen, fusing it to helium. These stars become red giants or supergiants, and they are red because the outer layers cool off as they move farther from the hot core. White dwarfs are what is left when a moderate star like our sun is at the end of its life. The outer layers move outwards in a red giant stage and then puff outwards as a planetary nebula, leaving the super-heated core behind as a white dwarf. To sum, the color of a star when it forms is due to its mass, which causes the star to burn at different temperatures. More massive stars are blue, small dwarf stars are red, and moderate stars are yellow.

The explosive death of a star is what?
a supernova, and that's not a "death", because it becomes a black dwarf (it is still a star, but it doesn't shine because it doesn't have any gases to burn anymore)Answera supernova, and that's not a "death", because it becomes a black dwarf (it is still a star, but it doesn't shine because it doesn't have any gases to burn anymore)
