Mass–luminosity relation — In astrophysics, the mass–luminosity relation is an equation giving the relationship between a star s mass and its luminosity. The relationship is represented by the equation: where L⊙ and M⊙ are the luminosity and mass of the sun and… … Wikipedia
Mass in special relativity — incorporates the general understandings from the concept of mass energy equivalence. Added to this concept is an additional complication resulting from the fact that mass is defined in two different ways in special relativity: one way defines… … Wikipedia

Relation de Faber-Jackson — La relation de Faber Jackson est une loi empirique qui relie la magnitude absolue ou la luminosité L à la dispersion des vitesses σ des étoiles centrales des galaxies elliptiques. Elle permet la détermination des distances pour ce type de galaxie … Wikipédia en Français
M-sigma relation — The M sigma (or MBH σ) relation is an empirical correlation between the stellar velocity dispersion σ of a galaxy bulge and the mass M of the supermassive black hole at the galaxy s center. The relation can be expressed mathematically as A recent … Wikipedia
Dispersion relation — The refraction of a light in a prism is due to dispersion. In physics and electrical engineering, dispersion most often refers to frequency dependent effects in wave propagation. Note, however, that there are several other uses of the word… … Wikipedia
Effective mass — In solid state physics, a particle s effective mass is the mass it seems to carry in the semiclassical model of transport in a crystal. It can be shown that, under most conditions, electrons and holes in a crystal respond to electric and magnetic … Wikipedia
Tully-Fisher relation — In astronomy, the Tully Fisher relation, published by astronomers R. Brent Tully and J. Richard Fisher in 1977, is an empirical relationship between the intrinsic luminosity (proportional to the stellar mass) of a spiral galaxy and its velocity… … Wikipedia
