Super gigante roja
In astronomy, they are denominated red supergigantes to stars supergigantes (of class of brightness I) of ghastly type K or M. are the biggest stars (in terms of volume) that they are in the universe, although they are not the most massive and, as their name it indicates it, their surfaces are of reddish and lightly dark color.
The stars with more than some 10 solar masses, after consuming their hydrogen in the nucleus during the stage of main sequence, they become red supergigantes during their stage of coalition of helium. These stars are not the hottest, but rather, relatively, they are Also among the coldest contrary to the blue giants whose superficial temperatures vary between 28.000 and 50.000 K, those of these stars usually oscillate between 3000 and 4000 K.
