RED SUPER GIANT




===Star that is similar in nature but bigger and more massive than a red giant. Red super giants typically span several hundred times the diameter of the Sun and have masses of more than 10 times that of the Sun. They belong to luminosity class I and are of spectral type Mor K. ===


=== The red supergiant phase is extremely short-lived, lasting only a few hundred thousand to a million years. at most before ending in a supernova. It is believed that high-mass red super giants evolve to become Wolf-Rayed stars before exploding as type Lb or Lc supernovae, while those of lower mass eventually explode as type II supernovae. ===


=== Even though red super giants are extraordinary, clusters of them do stay present. In 2006, a team escorted by Don Figer of the Rochester Institute of Technology in New York announced it had found a massive cluster of about 20,000 stars, called RSGC1, which integrated 14 red super giants. Lying near the center of the Galaxy, it was the largest alignment of these stars ever recognized. ===
