red super giant

How long do red supergiants live?

Most red supergiants live a few tens of millions of years (depending on the size)

How is a red supergiant created?

Red Supergiants are created when the core runs out of hydrogen fuel supply and the star begins to collapse in on itself.The outer shells of hydrogen then begin to get hot enough to begin fusion.

Examples of red supergiants.

The best known example of a red supergiant is the star as Betelguese located on the shoulder of Orion.

How do red supergiants die?

red supergiants typically only last a few thousand years. within this period of time the sun continues to fuse heavier and heavier elements at the suns core. as the sun continues to fuse the heavy elements iron begans to build up the the core of the sun. the process of fusing uses up a lot of the stars energy. At this point the star usually explodes into a type II supernova

what is the luminosity of a red supergiant?

the luminosity of a red supergiant is 10,000- 1 million times the brightness of our sun

what is the mass of a red supergiant?

the mass of a red supergiant is about 8-12 the mass of our sun ( our sun's mass: 1.989 x 10^30 )

How hot is a red supergiant?

the surface temp of a red supergiant is about 3,500-4,500 kelvin

what is the difference between red giants and red supergiants?

there is really no agreed upon difference

What is Red Supergiant

An aging star that has used up its core hydrogen fuel supply.

what is the size of a red supergiant?

To put the size of a red supergiant into prespective, the radius of a red supergiant is 30-1000 times that of our sun(432,288)
