A 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 …

A Class B star is the second-brightest type of main sequence star. They are typically colored blue-white, slightly less blue than O-type stars. They are fairly rare, making up only 0.13% of main …

Type-B stars have a Class B spectral type, giving them a blue - white color. This category has the following 12 subcategories, out of 12 total. The following 14 pages are in this category, out of …

B-type stars are a class of hot, luminous stars that are characterized by their blue-white appearance and high surface temperatures. These stars are an important component of the …

b-Lines: A triplet of spectral lines of neutral magnesium 5167-5184. B Star: Stars of spectral type B are blue-white stars with surface temperatures of about 11,00-28,000 K, whose spectra are …

Astronomers identify B-type stars by the presence of neutral helium lines along with hydrogen lines in their spectra. They have typical (effective) temperatures between around 10,000 …

A B-type star is a hot, massive, and luminous star that is part of the main sequence classification in the Hertzsprung-Russell (H-R) diagram. These stars are characterized by their high surface …

A B-type star is an object exhibiting neutral helium lines in its spectrum, but no ionized helium lines. The latter are characteristic of O-type stars. Neutral helium lines are invisible in A-type …

Three approaches to modeling stellar structure (atmospheres) are considered, the characteristic properties of a mantle, and B stars and evolution are discussed.

A B-type star is a star within the B-class, a spectral class indicating stars with neutral helium and moderate hydrogen absorption lines, a blue-white color, and a surface temperature in the …
