What are the different types of stars in the universe?
WebAt solar metallicity, the least massive red dwarfs theoretically have temperatures around 1,700 K, while measurements of red dwarfs in the solar neighbourhood suggest the coolest stars have temperatures of about 2,075 K and spectral classes of about L2. WebA B-type main-sequence star (B V) is a main-sequence ( hydrogen -burning) star of spectral type B and luminosity class V. These stars have from 2 to 16 times the mass of the Sun and surface temperatures between 10,000 and 30,000 K. [1] B-type stars are extremely luminous and blue. cute girly car seat covers
