IN-SYNC. V. Stellar kinematics and dynamics in the Orion A Molecular Cloud
Nicola Da Rio, Jonathan C. Tan, Kevin R. Covey +14
The kinematics and dynamics of young stellar populations enable us to test theories of star formation. With this aim, we continue our analysis of the SDSS-III/APOGEE IN-SYNC survey…
IN-SYNC IV - The Young Stellar Population in the Orion A Molecular Cloud
Nicola Da Rio, Jonathan C. Tan, Kevin R. Covey +14
We present the results of the SDSS APOGEE INfrared Spectroscopy of Young Nebulous Clusters program (IN-SYNC) survey of the Orion A molecular cloud. This survey obtained high resolu…
Astrometry with MCAO at Gemini and at ELTs
Tobias K. Fritz, Nitya Kallivayalil, Eleazar R. Carrasco +11
We present in this study a first analysis of the astrometric error budget of absolute astrometry relative to background galaxies using adaptive optics. We use for this analysis mul…
IN-SYNC III: The dynamical state of IC 348 - A super-virial velocity dispersion and a puzzling sign of convergence
Michiel Cottaar, Kevin R. Covey, Jonathan B. Foster +11
Most field stars will have encountered the highest stellar density and hence the largest number of interactions in their birth environment. Yet the stellar dynamics during this cru…
Old open clusters in the outer Galactic disk
Giovanni Carraro, Douglas Geisler, Sandro Villanova +2
The outer parts of the Milky Way disk are believed to be one of the main arenas where the accretion of external material in the form of dwarf galaxies and subsequent formation of s…
Chemical Abundances in a Sample of Red Giants in the Open Cluster NGC 2420 from APOGEE
Diogo Souto, Katia Cunha, Verne Smith +20
NGC 2420 is a 2 Gyr-old well-populated open cluster that lies about 2 kpc beyond the solar circle, in the general direction of the Galactic anti-center. Most previous abundan…
