VISTA Variables in the Via Lactea (VVV): The public ESO near-IR variability survey of the Milky Way
D. Minniti, P. W. Lucas, J. P. Emerson +63
We describe the public ESO near-IR variability survey (VVV) scanning the Milky Way bulge and an adjacent section of the mid-plane where star formation activity is high. The survey…
A revolution in star cluster research: setting the scene
Richard de Grijs
Star clusters and their stellar populations play a significant role in the context of galaxy evolution, across space (from local to high redshift) and time (from currently forming…
Young massive star clusters: Achievements and challenges
Richard de Grijs
In spite of significant recent and ongoing research efforts, most of the early evolution and long-term fate of young massive star clusters remain clouded in uncertainties. Here, I…
The low-mass stellar mass functions of rich, compact clusters in the Large Magellanic Cloud
Q. Liu, R. de Grijs, L. C. Deng +2
Context. We use Hubble Space Telescope photometry of six rich, compact star clusters in the Large Magellanic Cloud (LMC), with ages ranging from 0.01 to 1.0 Gyr, to derive the clus…
Old stellar population synthesis: New age and mass estimates for Mayall II = G1
Jun Ma, Richard de Grijs, Zhou Fan +3
Mayall II = G1 is one of the most luminous globular clusters (GCs) in M31. Here, we determine its age and mass by comparing multicolor photometry with theoretical stellar populatio…
The initial mass function of the rich young cluster NGC 1818 in the Large Magellanic Cloud
Q. Liu, R. de Grijs, L. C. Deng +3
We use deep Hubble Space Telescope photometry of the rich, young (~20-45 Myr-old) star cluster NGC 1818 in the Large Magellanic Cloud to derive its stellar mass function (MF) down…
Using the minimum spanning tree to trace mass segregation
Richard J. Allison, Simon P. Goodwin, Richard J. Parker +3
We present a new method to detect and quantify mass segregation in star clusters. It compares the minimum spanning tree (MST) of massive stars with that of random stars. If mass se…
