The Gaia-ESO Survey: Evidence of atomic diffusion in M67?
C. Bertelli Motta, A. Pasquali, J. Richer +37
Investigating the chemical homogeneity of stars born from the same molecular cloud at virtually the same time is very important for our understanding of the chemical enrichment of…
New massive members of Cygnus OB2
S. R. Berlanas, A. Herrero, F. Comerón +3
The Cygnus complex is one of the most powerful star forming regions at a close distance from the Sun (~1.4 kpc). Its richest OB association Cygnus OB2 is known to harbor many tens…
Chemo-Dynamical Clustering applied to APOGEE data: Re-Discovering Globular Clusters
Boquan Chen, Elena D'Onghia, Stephen A. Pardy +4
We have developed a novel technique based on a clustering algorithm which searches for kinematically- and chemically-clustered stars in the APOGEE DR12 Cannon data. As compared to…
Observing the products of stellar evolution in the old open cluster M67 with APOGEE
Clio Bertelli Motta, Maurizio Salaris, Anna Pasquali +1
Recent works have shown how the [C/N] ratio in stars after the first dredge-up (FDU) can be used as an age estimator in virtue of its dependence on stellar mass. For this purpose,…
