The Law of Starformation in Disk Galaxies
J.Köppen
ABSTRACT Does the available Halpha-data from disk galaxies allow to distinguish between a SFR depending only on local current gas density and a more complicated SFR which also depends on galactocentric distance. What do the gas fractions tell us? These questions are answered with a practical Bayesian method we developed and which might be useful to address similar questions in other types of galaxies.
