The WAGGS project -- III. Discrepant mass-to-light ratios of Galactic globular clusters at high metallicity
H. Dalgleish, S. Kamann, C. Usher +10
Observed mass-to-light ratios (M/L) of metal-rich globular clusters (GCs) disagree with theoretical predictions. This discrepancy is of fundamental importance since stellar populat…
Extended main sequence turnoffs in open clusters as seen by Gaia -- II. The enigma of NGC 2509
M. de Juan Ovelar, S. Gossage, S. Kamann +5
We investigate the morphology of the colour-magnitude diagram (CMD) of the open cluster NGC 2509 in comparison with other Galactic open clusters of similar age using Gaia photometr…
Spectroscopic detection of multiple populations in the ~2 Gyr old cluster Hodge 6 in the LMC
K. Hollyhead, S. Martocchia, C. Lardo +8
We report the spectroscopic discovery of abundance spreads (i.e. multiple populations) in the ~2 Gyr old cluster in the LMC, Hodge 6. We use low resolution VLT FORS2 spectra of 15…
Extended Main Sequence Turnoffs in Open Clusters as Seen by Gaia: I. NGC 2818 and the Role of Stellar Rotation
N. Bastian, S. Kamann, I. Cabrera-Ziri +5
We present an analysis of the relatively low mass (~M), ~Myr, Galactic open cluster, NGC~2818, using Gaia DR2 results combined with VLT/FLAMES spectros…
