Star Formation Histories of Ultra-Faint Dwarf Galaxies: environmental differences between Magellanic and non-Magellanic satellites?
Elena Sacchi, Hannah Richstein, Nitya Kallivayalil +18
We present the color-magnitude diagrams and star formation histories (SFHs) of seven ultra-faint dwarf galaxies: Horologium 1, Hydra 2, Phoenix 2, Reticulum 2, Sagittarius 2, Trian…
APOGEE-2 Discovery of a Large Population of Relatively High-Metallicity Globular Cluster Debris
José G. Fernández-Trincado, Timothy C. Beers, Anna. B. A. Queiroz +13
We report the discovery of a new, chemically distinct population of relatively high-metallicity ([Fe/H] ) red giant stars with super-solar [N/Fe] () identifi…
APOGEE-2S Discovery of Light- and Heavy-Element Abundance Correlations in the Bulge Globular Cluster NGC 6380
José G. Fernández-Trincado, Timothy C. Beers, Beatriz Barbuy +11
We derive abundance ratios for nine stars in the relatively high-metallicity bulge globular cluster NGC 6380. We find a mean cluster metallicity between [Fe/H] and …
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,…
Symbiotic Stars in the APOGEE Survey: The Case of LIN 358 and SMC N73 (LIN 445a)
Jasmin E. Washington, Hannah M. Lewis, Borja Anguiano +9
LIN 358 and SMC N73 are two symbiotic binaries in the halo of the Small Magellanic Cloud, each composed of a hot white dwarf accreting from a cool giant companion. In this work, we…
A Spectroscopic Analysis of the California-Kepler Survey Sample: II. Correlations of Stellar Metallicities with Planetary Architectures
Luan Ghezzi, Cintia F. Martinez, Robert F. Wilson +3
We present independent and self-consistent metallicities for a sample of 807 planet-hosting stars from the California-Kepler Survey from an LTE spectroscopic analysis using a selec…
