Double-lined spectroscopic binaries in the APOGEE DR16 and DR17 data
Marina Kounkel, Kevin R. Covey, Keivan G. Stassun +25
APOGEE spectra offer 1 km s precision in the measurement of stellar radial velocities (RVs). This holds even when multiple stars are captured in the same spectrum,…
Active red giants: close binaries versus single rapid rotators
Patrick Gaulme, Jason Jackiewicz, Federico Spada +7
The objective of this work is to determine what fraction of red-giant (RG) stars shows photometric rotational modulation, and understand its origin. One of the underlying questions…
Homogeneous Analysis of Globular Clusters from the APOGEE Survey with the BACCHUS Code. II. The Southern Clusters and Overview
Szabolcs Mészáros, Thomas Masseron, D. A. García-Hernández +33
We investigate the Fe, C, N, O, Mg, Al, Si, K, Ca, Ce and Nd abundances of 2283 red giant stars in 31 globular clusters from high-resolution spectra observed in both the northern a…
A homogeneous analysis of globular clusters from the APOGEE survey with the BACCHUS code. I. The Northern clusters
T. Masseron, D. A. García-Hernández, Sz. Mészáros +12
We analyze a large sample of 885 GCs giants from the APOGEE survey. We used the Cannon results to separate the red giant branch and the asymptotic giant branch stars, not only allo…
44 New & Known M Dwarf Multiples In The SDSS-III/APOGEE M Dwarf Ancillary Science Sample
Jacob Skinner, Kevin R. Covey, Chad F. Bender +28
Binary stars make up a significant portion of all stellar systems. Consequently, an understanding of the bulk properties of binary stars is necessary for a full picture of star for…
