In astrophysics, the mass–luminosity relation is an equation giving the relationship between a star's mass and its luminosity, first noted by Jakob Karl Ernst Halm. The relationship is represented by the equation: $${\displaystyle {\frac {L}{L_{\odot }}}=\left({\frac {M}{M_{\odot }}}\right)^{a}}$$where … Ver mais Deriving a theoretically exact mass/luminosity relation requires finding the energy generation equation and building a thermodynamic model of the inside of a star. However, the basic relation L ∝ M can … Ver mais To the first approximation, stars are black body radiators with a surface area of 4πR . Thus, from the Stefan–Boltzmann law, the luminosity is related to the surface temperature TS, and through it to the color of the star, by The luminosity is … Ver mais WebTerms in this set (25) What do we mean by a star's spectral type, and how is spectral type related to surface temperature and color. Spectral types are a way of classifying stars according to their color or what spectral lines we see in their light. The spectral types run OBAFGKM, where O stars are the hottest and M are the coolest.
Webmass-luminosity relation, in astronomy, law stating that the luminosity of a star is proportional to some power of the mass of the star. More massive stars are in general more luminous. For stars on the main sequence of the Hertzsprung-Russell diagram, it is found empirically that the luminosity varies as the 3.5 power of the mass.This means that if … WebThe external galaxies show an extremely large range in their total luminosities. The intrinsically faintest are the extreme dwarf elliptical galaxies, such as the Ursa Minor dwarf, which has a luminosity of approximately 100,000 Suns. The most luminous galaxies are those that contain quasars at their centres. These remarkably bright superactive nuclei …

For main-sequence stars, the Luminosity is related to the temperature by the expression L ≈ M 3.5. The reason for the 3.5 exponent is because the relationship best fits some stars at L = M 3 up to L = M 4. For non-main-sequence stars, you probably need a relationship between density and Luminosity. Share. grand cereals
