J/ApJ/706/516  Gas content of star-forming galaxies  (Pflamm-Altenburg+, 2009)

The fundamental gas depletion and stellar-mass buildup times of star-forming galaxies. Pflamm-Altenburg J., Kroupa P. <Astrophys. J., 706, 516-524 (2009)> =2009ApJ...706..516P
ADC_Keywords: Galaxies, nearby ; Magnitudes, absolute Keywords: cosmology: observations - galaxies: evolution - galaxies: fundamental parameters - stars: formation Abstract: Stars do not form continuously distributed over star-forming galaxies. They form in star clusters of different masses. This nature of clustered star formation is taken into account in the theory of the integrated galactic stellar initial mass function (IGIMF) in which the galaxy-wide initial mass function (IMF) on galaxy-wide scales is calculated by adding all IMFs of young star clusters. For massive stars, the IGIMF is steeper than the universal IMF in star clusters and steepens with decreasing star formation rate (SFR) which is called the IGIMF effect. The current SFR and the total Hα luminosity of galaxies therefore scale nonlinearly in the IGIMF theory compared to the classical case in which the galaxy-wide IMF is assumed to be constant and identical to the IMF in star clusters. Here we apply for the first time the revised SFR-L relation on a sample of local volume star-forming galaxies with measured Hα luminosities. File Summary:
