"In astronomy, the Kennicutt–Schmidt (or simply the Schmidt Law) is an empirical relation between the gas density and star formation rate (SFR) in a given region. The relation was first examined by Maarten Schmidt in a 1959 paper in which he proposed that the SFR surface density scales as some positive power
of the local gas surface density.[1] i.e..
In general the SFR surface density
is in units of solar masses per year per square parsec 
and the gas surface density in grams per square parsec 
. Using an analysis of gaseous helium and young stars in the solar neighborhood, the local density of white dwarfs and their luminosity function, and the local helium density, Schmidt suggested a value of 
(and very likely between 1 and 3). All of the data used were gathered from the Milky Way, and specifically the solar-neighborhood."'via Blog this'
