B type main sequence stars
WebMost stars are currently classified under the Morgan–Keenan (MK) system using the letters O, B, A, F, G, K, and M, a sequence from the hottest ( O type) to the coolest ( M type). Each letter class is then subdivided using … WebSame as Fig. B.1, but for examples of О III (leftpanel) and Si III emission lines (rightpanel), for 10 Lac and three other sample stars.

B type main sequence stars
Did you know?
WebThe great majority are aligned along a narrow sequence running from the upper left (hot, highly luminous) to the lower right (cool, less luminous). This band of points is called the main sequence. It represents a relationship between temperature and luminosity that is followed by most stars. 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 temperatures between 10,000 and 30,000 K. B-type stars are extremely luminous and blue. Their spectra have strong … See more This class of stars was introduced with the Harvard sequence of stellar spectra and published in the Revised Harvard photometry catalogue. The definition of type B-type stars was the presence of non- See more Spectral objects known as "Be stars" are massive yet non-supergiant entities that notably have, or had at some time, 1 or more See more Some of the B-type stars of stellar class B0–B3 exhibit unusually strong lines of non-ionized helium. These chemically peculiar stars are … See more • Herbig Ae/Be star • Stellar classification, Class B • Star count See more Type-B stars don't have a corona and lack a convection zone in their outer atmosphere. They have a higher mass loss rate than smaller stars such as the Sun, and their stellar wind has velocities of about 3,000 km/s. The energy generation in main-sequence … See more The revised Yerkes Atlas system (Johnson & Morgan 1953) listed a dense grid of B-type dwarf spectral standard stars, however not all of these have survived to this day as … See more B-type stars known to have planets include the main-sequence B-type HIP 78530 and Mu² Scorpii.
