When efficient star formation drives cluster formation

G Parmentier, U Fritze - The Astrophysical Journal, 2008 - iopscience.iop.org
We investigate the impact of the star-formation efficiency (SFE) in cluster-forming cores (ie,
local SFE) on the evolution of mass in star clusters (SCs) over the age range 1–100 Myr …

Detecting metal-rich intermediate-age globular clusters in NGC4570 using K-band photometry

R Kotulla, U Fritze, P Anders - Astrophysics and Space Science, 2009 - Springer
Globular cluster systems (GCSs) of most early-type galaxies feature two peaks in their
optical colour distributions. Blue-peak globular clusters (GCs) are believed to be old and …

Ages of Globular Cluster Systems and the Relation to Galaxy Morphology

AL Chies-Santos, SS Larsen, H Kuntschner… - Proceedings of the …, 2010 - cambridge.org
We investigate the age distributions of GC systems in 14 E/S0 galaxies by carrying out a
differential comparison of the (g–z) vs.(g–K) two-colour diagrams for different GC systems …

Early dynamical evolution of star cluster systems

G Parmentier - Proceedings of the International Astronomical Union, 2009 - cambridge.org
Violent relaxation, the protocluster dynamical response to the expulsion of its residual star-
forming gas, is a short albeit crucial episode in the evolution of star clusters and star cluster …
