Orbital Parameters and Binary Properties of 37 FGK stars in the Cores of Open Clusters NGC 2516 and NGC 2422
Isabel Lipartito, John I. Bailey, Timothy D. Brandt +4
We present orbits for 24 binaries in the field of open cluster NGC 2516 (~150 Myr) and 13 binaries in the field of open cluster NGC 2422 (~130 Myr) using results from a multi-year…
The Binary Fraction of Stars in Dwarf Galaxies: the Cases of Draco and Ursa Minor
Meghin Spencer, Mario Mateo, Edward Olszewski +3
Measuring the frequency of binary stars in dwarf spheroidal galaxies (dSphs) requires data taken over long time intervals. We combine radial velocity measurements from five literat…
The binary fraction of stars in dwarf galaxies: the case of Leo II
Meghin Spencer, Mario Mateo, Matthew Walker +4
We combine precision radial velocity data from four different published works of the stars in the Leo II dwarf spheroidal galaxy. This yields a dataset that spans 19 years, has 14…
A multi-epoch kinematic study of the remote dwarf spheroidal galaxy Leo II
Meghin Spencer, Mario Mateo, Matthew Walker +1
We conducted a large spectroscopic survey of 336 red giants in the direction of the Leo II dwarf galaxy using Hectochelle on the MMT, and conclude that 175 of them are members base…
At the survey limits: discovery of the Aquarius 2 dwarf galaxy in the VST ATLAS and the SDSS data
G. Torrealba, S. E. Koposov, V. Belokurov +7
We announce the discovery of the Aquarius~2 dwarf galaxy, a new distant satellite of the Milky Way, detected on the fringes of the VST ATLAS and the SDSS surveys. The object was or…
Spectroscopic Binaries in the Orion Nebula Cluster and NGC 2264
Marina Kounkel, Lee Hartmann, John J. Tobin +3
We examine the spectroscopic binary population for two massive nearby regions of clustered star formation, the Orion Nebula Cluster and NGC 2264, supplementing the data presented b…
