Young massive star clusters in nearby spiral galaxies. III. Correlations between cluster populations and host galaxy properties.

LARSEN S.S. and RICHTLER T.

Abstract (from CDS):

We present an analysis of correlations between integrated properties of galaxies and their populations of young massive star clusters. Data for 21 nearby galaxies presented by Larsen & Richtler (1999A&A...345...59L) are used together with literature data for 10 additional galaxies, spanning a range in specific U-band cluster luminosity TL(U) from 0 to 15. We find that TL(U) correlates with several observable host galaxy parameters, in particular the ratio of Far-Infrared (FIR) to B-band flux and the surface brightness. Taking the FIR luminosity as an indicator of the star formation rate (SFR), it is found that TL(U) correlates very well with the SFR per unit area. A similar correlation is seen between TL(U) and the atomic hydrogen surface density. The cluster formation efficiency seems to depend on the SFR in a continuous way, rather than being related to any particularly violent mode of star formation. We discuss fundamental features of possible scenarios for cluster formation. One possibility is that the correlation between TL(U) and SFR is due to a common controlling parameter, most probably the high density of the ISM. Another scenario conceives a high TL(U) as resulting from the energy input from many massive stars in case of a high SFR.
