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…

An Extragalactic Chromosome Map: The intermediate age SMC Cluster Lindsay 1

S. Saracino, N. Bastian, V. Kozhurina-Platais +8

The discovery of star-to-star abundance variations (a.k.a. multiple populations - MPs) within globular clusters (GCs), which are generally not found in the field or in lower mass o…

Multiple Populations in Integrated Light Spectroscopy of Intermediate Age Clusters

Nate Bastian, Christopher Usher, Sebastian Kamann +9

The presence of star-to-star light-element abundance variations (a.k.a. multiple populations, MPs) appears to be ubiquitous within old and massive clusters in the Milky Way and all…

Combined Effects of Rotation and Age Spreads on Extended Main Sequence Turn Offs

Seth Gossage, Charlie Conroy, Aaron Dotter +10

The extended main sequence turn offs (eMSTOs) of several young to intermediate age clusters are examined in the Magellanic Clouds and the Milky Way. We explore the effects of exten…

The search for multiple populations in Magellanic Clouds clusters - V. Correlation between cluster age and abundance spreads

S. Martocchia, E. Dalessandro, C. Lardo +14

In our HST photometric survey, we have been searching for multiple stellar populations (MPs) in Magellanic Clouds (MCs) massive star clusters which span a significant range of ages…

Constant light element abundances suggest that the extended P1 in NGC 2808 is not a consequence of CNO-cycle nucleosynthesis

I. Cabrera-Ziri, C. Lardo, A. Mucciarelli

Recent photometric results have identified a new population among globular cluster stars. This population, referred to as the ``extended P1'', has been suggested to be the manifest…

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…
