Superstar
The superstar is essentially a star with a radius and brightness that is larger than the main sequence star but has the same surface temperature. Typically, the radius of the superstar is 10 to 100 times the radius of the sun and 10 to 1,000 times the brightness of the sun. A star that is brighter than a superstar is a superstar and super superstar; a high temperature, bright main sequence star is sometimes classified as a star. In addition, because of their high brightness and large radii, the stars are located above the main sequence star (in the York spectrum classification for the brightness classification V), and correspond to the photometric classification of II or III. ...
