Stars having temperature about 30,000 degree K are called Blue stars.


"Blue stars are stars that have at least 3 times the mass of the Sun and up. Whether a star has 10 times the mass of the Sun or 150 solar masses, it's going to appear blue to our eyes. An example of a blue star is the familiar Rigel, the brightest star in the constellation Orion and the 6th brightest star in the sky.Dec 24, 2015"
