Massive young clusters in the Milky Way and the Scutum Complex
The last decade has brought the discovery of a large number of massive (M > 10000 M?) young open clusters in the Milky Way, which had previously not been...
MIUSCAT: extended MILES spectral coverage - II. Constraints from optical photometry
In this work, we show a comprehensive comparison of our new stellar population synthesis (SPS) MIUSCAT models with photometric data of globular clusters (GCs)...
Modeling the ionizing spectra of H II regions: individual stars versus stellar ensembles
Aims: We study how IMF sampling affects the ionizing flux and emission line spectra of low mass stellar clusters. Methods: We performed 2 × 106 Monte Carlo...
Multiple stellar populations in Magellanic Cloud clusters. I. An ordinary feature for intermediate age globulars in the LMC?
Context: The discovery of multiple main sequences (MS) in the massive clusters NGC 2808 and Omega Centauri, along with multiple subgiant branches in NGC 1851...
Multiplicity of the red supergiant population in the young massive cluster NGC 330
Context. The multiplicity properties of massive stars are one of the important outstanding issues in stellar evolution. Quantifying the binary statistics of all...
New cluster candidates in dwarf galaxies of the Local Group
V and I images of the nearby dIrr galaxies Sextans A and Sextans B were searched for the clusters. The cadidates were selected, from a sample of non-stellar...
Nitrogen abundances of the Be-type stars in 30 Doradus
A sub-set of the 67 Be-type stars observed in 30 Doradus during the VLT-FLAMES Tarantula Survey (VFTS) campaign have been analysed to estimate atmospheric...
Nuclear star formation in the hotspot galaxy NGC 2903
We present high-resolution near-infrared imaging obtained using adaptive optics and HST/NICMOS, and ground-based spectroscopy of the hotspot galaxy NGC 2903...
On ageing star clusters using red supergiants independent of the fraction of interacting binary stars
We use the Binary Population and Spectral Synthesis models to test the recent suggestion that red supergiants can provide an accurate age estimate of a coeval...
