F type star mass

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 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.
