On the evolution of the SFR in galactic disks
Source: Astrophysics and Space Science, Volume 284, Number 2, 2003 , pp. 731-734(4)
A simple semi-empirical model of the evolution of observed ring-shaped radial distributions of SFR surface density in galaxies NGC 628 and NGC 6946 provides us with exponential stellar disks with cooresponding scale length of the surface brightness radial distributions and constraints for the some nonobservable parameters: characteristic SFR decreasing time scale, characteristic collapse time scale, etc.
