The relation between the most-massive star and its parental star cluster mass
C. Weidner, P. Kroupa, I. Bonnell
We present a thorough literature study of the most-massive star, m_max, in several young star clusters in order to assess whether or not star clusters are populated from the stella…
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…
Chemo-Archaeological Downsizing in a Hierarchical Universe: Impact of a Top Heavy IGIMF
I. D. Gargiulo, S. A. Cora, N. D. Padilla +6
We make use of a semi-analytical model of galaxy formation to investigate the origin of the observed correlation between [a/Fe] abundance ratios and stellar mass in elliptical gala…
Implications for the formation of star clusters from extra-galactic star-formation rates
C. Weidner, P. Kroupa, S. S. Larsen
Observations indicate that young massive star clusters in spiral and dwarf galaxies follow a relation between luminosity of the brightest young cluster and the star-formation rate…
Mass accretion rates from multi-band photometry in the Carina Nebula: the case of Trumpler 14
G. Beccari, G. DeMarchi, N. Panagia +5
We present a study of the mass accretion rates of pre-Main Sequence (PMS) stars in the cluster Trumpler 14 (Tr14) in the Carina Nebula. Using optical multi-band photometry we were…
Field O stars: formed in situ or as runaways?
V. V. Gvaramadze, C. Weidner, P. Kroupa +1
A significant fraction of massive stars in the Milky Way and other galaxies are located far from star clusters. It is known that some of these stars are runaways and therefore most…
