Red+Supergiants

Red super giants It is an object in space similar to a star but more bigger. A star which is over 100 times bigger in diameter and is 10 times more the mass of a normal sun is suited to be called a Red super Giant. The super giants are listed in the Luminosity I (how bright the objects glows compared to the sun). in spectral type the super Giant belongs to M’’ or ‘K’ the spectral type is the way it is assigned depending on the characteristics of the spectrum.

The red super Giants only last to about hundred thousand to a million years ending in a supernova. The really high-mass red super giants turn into Wolf-Rayet stars before exploding those with low mass who cause supernovas are not as big super novas as the high mass.

Because of the largeness of the stars and briefness of the red supergiants, supergiants are becoming really rare to find. In the Galaxies there are only 200. some more popular are the Antares and the Betelgeuse, and the biggest star know to man is the Mu Cephei (also known as garnet star).

Red super giant cluster Even when super giants are rare left over (clusters) do exist. In 2006 a team led by Don Figer from the Rochester Institute of technology (RIT) had announced that they had found leftovers of 20,000 stars they named it RSGC1. The RSGC1 included of 14 red supergiants. It was located near the centre of the galaxies. Later in the year 2007 Ben Davies from RIT and a team with Figer said they found a even bigger collection of red Super Giants. There was 26 Red Super Giants that formed a big cluster this was named RSGC2. this was only few hundred Light Years awaya from RSGC1. Both being 20 million years old RSGC2 has twice as more Red Super Giants making it the biggest Clusters. There is little evidence of star formation. RSGC1 and 2 are both near the Scutum-Crux spiral arm of the Galaxy Scutum-Crux spiral
