Origins of the Evil Eye: M64's Stellar Halo Reveals the Recent Accretion of an SMC-mass Satellite
Adam Smercina, Eric F. Bell, Paul A. Price +9
M64, often called the "Evil Eye" galaxy, is unique among local galaxies. Beyond its dramatic, dusty nucleus, it also hosts an outer gas disk that counter-rotates relative to its st…
Chemical tagging in the SDSS-III/APOGEE survey: new identifications of halo stars with globular cluster origins
Sarah Martell, Matthew Shetrone, Sara Lucatello +6
We present new identifications of five red giant stars in the Galactic halo with chemical abundance patterns that indicate they originally formed in globular clusters. Using data f…
Young alpha-enriched giant stars in the solar neighbourhood
Marie Martig, Hans-Walter Rix, Victor Silva Aguirre +31
We derive age constraints for 1639 red giants in the APOKASC sample for which seismic parameters from Kepler, as well as effective temperatures, metallicities and [alpha/Fe] values…
Asteroseismology of Metal-Poor Red Giants Observed by TESS
Corin Marasco, Jamie Tayar, David Nidever
Galactic archeology has long been limited by a lack of precise masses and ages for metal-poor stars in the Milky Way's thick disk. However, with TESS providing a growing number of…
High-resolution, H band Spectroscopy of Be Stars with SDSS-III/APOGEE: I. New Be Stars, Line Identifications, and Line Profiles
S. Drew Chojnowski, David G. Whelan, John P. Wisniewski +26
APOGEE has amassed the largest ever collection of multi-epoch, high-resolution (R~22,500), H-band spectra for B-type emission line (Be) stars. The 128/238 APOGEE Be stars for which…
The Nineteenth Data Release of the Sloan Digital Sky Survey
SDSS Collaboration, Gautham Adamane Pallathadka, Mojgan Aghakhanloo +209
Mapping the local and distant Universe is key to our understanding of it. For decades, the Sloan Digital Sky Survey (SDSS) has made a concerted effort to map millions of celestial…
