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. B-type stars are extremely luminous and blue. Their spectra have strong neutral helium absorption lines, which are … http://www.atlasoftheuniverse.com/startype.html
WebThe mass converted into energy through burning will be a fraction f of the total mass of the star. E = f M c2 where Combining the last two equations, we have the following expression for the main sequence lifetime: tMS ∼ M/L Using the mass-luminosity relationship for main sequence stars: L ∼ M3.5
WebAn F-type main-sequence star (F V) is a main-sequence, hydrogen-fusing star of spectral type F and luminosity class V. These stars have from 1.0 to 1.4 times the mass of the … WebIn stars of spectral type F, the lines of neutral atoms are weak relative to those of ionized atoms. The hydrogen lines are stronger, attaining their maximum intensities in A-type stars, in which the surface temperature is about 9,000 K. Thereafter, these absorption lines gradually fade as the hydrogen becomes ionized.
WebAn F-type main-sequence star (F V) is a main-sequence, hydrogen -fusing star of spectral type F and luminosity class V. These stars have from 1.0 to 1.4 times the mass of the Sun and surface temperatures between 6,000 and 7,600 K. [2] Tables VII and VIII. This temperature range gives the F-type stars a whitish hue when observed by the atmosphere.
The stellar classification system is taxonomic, based on type specimens, similar to classification of species in biology: The categories are defined by one or more standard stars for each category and sub-category, with an associated description of the distinguishing features. Stars are often referred to as early or late types.

It's a matter of algebra to tease out the mass by rearranging the equation to solve for M . So, without ever touching a star, astronomers use mathematics and known physical laws to figure out its mass. how to soak a gammon jointWebThe hotter a star is, the rarer it is.
