Hubble–Reynolds law
The Hubble–Reynolds law models the surface brightness of elliptical galaxies as
Where is the surface brightness at radius , is the central brightness, and is the radius at which the surface brightness is diminished by a factor of 1/4. It is asymptotically similar to the De Vaucouleurs' law which is a special case of the Sersic profile for elliptical galaxies.[1]
The law is named for the astronomers Edwin Hubble and John Henry Reynolds.
