Abstract

Star formation in spiral galaxies has been studied by making use of 21 cm observations, observations of H band (1.6 µm), blue band magnitudes and far-infrared data from IRAS. It is found that the luminosities in the various bands are well correlated with the dynamic mass of the galaxies. From these, it is inferred that the star formation rate (SFR) and the IMF are about the same averaged over ∼107 and ∼109 years, whereas SFR averaged over the life time of the galaxy is higher. Also more massive galaxies have had more star formation in the past. There is inconclusive evidence for a correlation between far-IR luminosity and MHI the mass of neutral hydrogen.
