The Second Data Release of the Survey of the MAgellanic Stellar History (SMASH)
David L. Nidever, Knut Olsen, Yumi Choi +32
The Large and Small Magellanic Clouds (LMC and SMC) are the largest satellite galaxies of the Milky Way and close enough to allow for a detailed exploration of their structure and…
HD 63021: Chromospheric Activity and Mass Transfer in a Close Binary
D. G. Whelan, S. D. Chojnowski, J. Labadie-Bartz +13
Prompted by X-ray detections from multiple surveys, we investigated the A-type star HD 63021 and found that it is a double-lined spectroscopic binary with highly variable emission…
Are the Milky Way and Andromeda unusual? A comparison with Milky Way and Andromeda Analogs
Nicholas Fraser Boardman, Gail Zasowski, Jeffrey Newman +10
Our Milky Way provides a unique test case for galaxy evolution models, thanks to our privileged position within the Milky Way's disc. This position also complicates comparisons bet…
Discovery of an Ultra-Faint Stellar System near the Magellanic Clouds with the DECam Local Volume Exploration (DELVE) Survey
W. Cerny, A. B. Pace, A. Drlica-Wagner +29
We report the discovery of a new ultra-faint stellar system found near the Magellanic Clouds in the DECam Local Volume Exploration (DELVE) Survey. This new system, DELVE J015568…
SMASHing the low surface brightness SMC
Pol Massana, Noelia E. D. Noël, David L. Nidever +22
The periphery of the Small Magellanic Cloud (SMC) can unlock important information regarding galaxy formation and evolution in interacting systems. Here, we present a detailed stud…
APOGEE Data and Spectral Analysis from SDSS Data Release 16: Seven Years of Observations Including First Results from APOGEE-South
Henrik Jönsson, Jon A. Holtzman, Carlos Allende Prieto +20
The spectral analysis and data products in Data Release 16 (DR16; December 2019) from the high-resolution near-infrared APOGEE-2/SDSS-IV survey are described. Compared to the previ…
Stellar parameters for the First Release of the MaStar Library: An Empirical Approach
Yan-Ping Chen, Renbin Yan, Claudia Maraston +10
We report the stellar atmospheric parameters for 7503 spectra contained in the first release of the MaNGA stellar library (MaStar) in SDSS DR15. The first release of MaStar contain…
The Large Magellanic Cloud stellar content with SMASH: I. Assessing the stability of the Magellanic spiral arms
T. Ruiz-Lara, C. Gallart, M. Monelli +23
The Large Magellanic Cloud (LMC) is the closest and most studied example of an irregular galaxy. Among its principal defining morphological features, its off-centred bar and single…
Spectral classification of B stars: The empirical sequence using SDSS-IV/APOGEE near-IR data
Valeria G. Ramírez-Preciado, Alexandre Román-Lópes, Carlos G. Román-Zuñiga +5
We present a semi-empirical spectral classification scheme for normal B-type stars using near-infrared spectra (1.5-1.7 m) from the SDSS APOGEE2-N DR14 database. The main motiva…
Close Binary Companions to APOGEE DR16 Stars: 20,000 Binary-star Systems Across the Color-Magnitude Diagram
Adrian M. Price-Whelan, David W. Hogg, Hans-Walter Rix +20
Many problems in contemporary astrophysics---from understanding the formation of black holes to untangling the chemical evolution of galaxies---rely on knowledge about binary stars…
