A Search for EHB Pulsators in the Globular Cluster NGC 6752
M. Catelan, G. E. Prieto, M. Zoccali +8
We describe the status of a project whose main goal is to detect variability along the extreme horizontal branch of the globular cluster NGC 6752. Based on Magellan 6.5m data, prel…
Converting Halpha luminosities into SFRs
Jan Pflamm-Altenburg, Carsten Weidner, Pavel Kroupa
Star-formation rates (SFRs) of galaxies are commonly calculated by converting the measured Halpha luminosities (L_Halpha) into current SFRs. This conversion is based on a constant…
Converting H Luminosities into Star Formation Rates
Jan Pflamm-Altenburg, Carsten Weidner, Pavel Kroupa
The recent finding that the IGIMF (integrated galaxial initial stellar mass function) composed of all newly formed stars in all young star clusters has, in dependence of the SFR, a…
On the infant weight loss of low- to intermediate-mass star clusters
C. Weidner, P. Kroupa, D. E. A. Nuernberger +1
Star clusters are born in a highly compact configuration, typically with radii of less than about 1 pc roughly independently of mass. Since the star-formation efficiency is less th…
