Answer (1 of 3): The Hertzsprung-Russell diagram, or HR shows the existence of a dependence between stellar luminosity and surface temperature, most of the points, corresponding to the various stars, are distributed on a diagonal band that joins the zone at low temperatures (red) and low brightne. A blue star will burn more fuel than a red star. The smaller stars collapse due to their own gravity as there is no more fusion reaction. However that is not the case. If the star doesn't have enough gravity to do that, it will release its cooling outer layers into space.) It's very tiny, but very dense. The largest know red supergiant is around 1800 times larger than the sun. A star that massive needs a lot of fuel to stay bright. . Blue supergiant stars are .

The distance was not measured; astronomers originally had two radical. Due to the very high fuel consumption, blue giants have a very short lifespan (less than a million years in some cases, up to a billion in slightly cooler blue stars). The star then turns into a red giant. Think of them as the 800-pound gorillas of the stars. Giant stars with many times the mass of our Sun burn through their gas much faster. Astronomers categorize blue giants as type O or B stars, belonging to the luminosity class III. HD 162437 is a Giant Star.

For this reason, Achernar is flattened and its poles are hotter than its equator . Stars like Spica is hotter than Betelgeuse which is a dying star and therefore more blue. This appears black because it is so dense that even light cannot escape. Blue Dwarf Star Facts. When all the helium is used up in the core, and no other element is left to be used as a fuel, the red giant stars transform to white dwarf stars. The largest only last a few million years.
