On the fraction of star clusters surviving the embedded phase.
GODDARD Q.E., BASTIAN N. and KENNICUTT R.C.
Abstract (from CDS):
Using the observed cluster population for NGC 3256 we calculate the implied mass of clusters younger than 10-Myr old, and convert this to a cluster formation rate over the last 10Myr. Comparison of this value with the SFR indicates the fraction of stars found within bound clusters after the embedded phase of cluster formation, Γ, is 22.9±7.39.8 per cent for NGC 3256. We carried out an in-depth analysis into the errors associated with such calculations showing that errors introduced by the SSP fitting must be taken into account and an unconstrained metallicity adds to these uncertainties. Observational biases should also be considered.
Using published cluster population data sets we calculate Γ for six other galaxies and examine how Γ varies with environment. We show that Γ increases with the SFR density and can be described as a power-law type relation of the form Γ (percent) = (29.0±6.0) Σ0.24±0.04SFR(M☉/yr/kpc2).
