Ne22 distillation and the cooling sequence of the old metal-rich open cluster NGC 6791
Maurizio Salaris, Simon Blouin, Santi Cassisi +1
Recent Monte Carlo plasma simulations to study in crystallizing carbon-oxygen (CO) white dwarfs (WDs) the phase separation of Ne22 (the most abundant metal after carbon and oxygen)…
Astrometric star-cluster membership probability: application to the case of M 37 with Gaia EDR3
M. Griggio, L. R. Bedin
In this work, starting from the well-accepted relations in literature, we introduce a new formalism to compute the astrometric membership probabilities for sources in star clusters…
Multiple stellar populations in Magellanic Cloud clusters. III. The first evidence of an extended main sequence turn-off in a young cluster: NGC1856
A. P. Milone, L. R. Bedin, G. Piotto +7
Recent studies have shown that the extended main-sequence turn off (eMSTO) is a common feature of intermediate-age star clusters in the Magellanic Clouds (MCs). The most simple exp…
Stellar parameters of early M dwarfs from ratios of spectral features at optical wavelengths
J. Maldonado, L. Affer, G. Micela +29
(Abridged) Low-mass stars have been recognised as promising targets in the search for rocky, small planets with the potential of supporting life. Doppler search programmes using hi…
A search for spectroscopic binaries in the galactic globular cluster M4. Based on 5973 individual spectra collected at VLT
V. Sommariva, G. Piotto, M. Rejkuba +4
We present a large multi-epoch high resolution spectroscopic investigation for the search of binary candidates in the Galactic Globular Cluster (GGC) M4. The aim of our work is the…
NGC 6791: an exotic open cluster or the nucleus of a tidally disrupted galaxy?
Giovanni Carraro, Sandro Villanova, Pierre Demarque +3
We report on high resolution Echelle spectroscopy of 20 giant stars in the Galactic old open clusters NGC 6791 obtained with Hydra at the WIYN telescope. High precision radial velo…
