Cracking the relation between mass and 1P-star fraction of globular clusters: III. Initial distributions of in-situ and ex-situ clusters
Geneviève Parmentier
Galactic globular clusters consist of two main stellar populations, the pristine (1P) and polluted (2P) stars. The fraction of 1P stars in clusters, , is a decreasing funct…
Cracking the relation between mass and 1P-star fraction of globular clusters: II. The masses in 1P and 2P stars as a second tool
Geneviève Parmentier
Galactic globular clusters contain two main groups of stars, the pristine or 1P stars, and the polluted or 2P stars. The pristine-star fraction in clusters, , is a decreasi…
The star cluster survivability after gas expulsion is independent of the impact of the Galactic tidal field
B. Shukirgaliyev, G. Parmentier, P. Berczik +1
We study the impact of the tidal field on the survivability of star clusters following instantaneous gas expulsion. Our model clusters are formed with a centrally-peaked star-forma…
A cautionary note about composite Galactic star formation relations
Genevieve Parmentier
We explore the pitfalls which affect the comparison of the star-formation (SF) relation for nearby molecular clouds with that for distant compact molecular clumps. We show that bot…
The evolutionary tracks of young massive star clusters
S. Pfalzner, G. Parmentier, M. Steinhausen +2
Stars mostly form in groups consisting of a few dozen to several ten thousand members. For 30 years, theoretical models provide a basic concept of how such star clusters form and d…
Stellar age spreads in clusters as imprints of cluster-parent clump densities
Genevieve Parmentier, Susanne Pfalzner, Eva K. Grebel
It has recently been suggested that high-density clusters have stellar age distributions narrower than that of the Orion Nebula Cluster, indicating a possible trend of narrower age…
The evolution of the surface brightness of a star cluster as a result of residual star-forming gas expulsion
F. Lueghausen, G. Parmentier, J. Pflamm-Altenburg +1
Direct N-body calculations are presented of the early evolution of exposed clusters to quantify the influence of gas expulsion on the time-varying surface brightness. By assuming t…
What cluster gas expulsion can tell us about star formation, cluster environment and galaxy evolution
Genevieve Parmentier
Violent relaxation -- the protocluster dynamical response to the expulsion of its leftover star forming gas -- is a short albeit crucial episode in the evolution of star clusters a…
