Disentangling the Galactic Halo with APOGEE: I. Chemical and Kinematical Investigation of Distinct Metal-Poor Populations
Christian R. Hayes, Steven R. Majewski, Matthew Shetrone +21
We find two chemically distinct populations separated relatively cleanly in the [Fe/H] - [Mg/Fe] plane, but also distinguished in other chemical planes, among metal-poor stars (pri…
Metallicity effect on stellar granulation detected from oscillating red giants in open clusters
E. Corsaro, S. Mathur, R. A. García +9
The effect of metallicity on the granulation activity in stars is still poorly understood. Available spectroscopic parameters from the updated APOGEE-\textit{Kepler} catalog, coupl…
Atypical Mg-poor Milky Way field stars with globular cluster second-generation like chemical patterns
J. G. Fernández-Trincado, O. Zamora, D. A. Garcia-Hernandez +48
We report the peculiar chemical abundance patterns of eleven atypical Milky Way (MW) field red giant stars observed by the Apache Point Observatory Galactic Evolution Experiment (A…
A modern study of HD166734: a massive supergiant system
L. Mahy, Y. Damerdji, E. Gosset +4
Aims. HD166734 is an eccentric eclipsing binary system composed of two supergiant O-type stars, orbiting with a 34.5-day period. In this rare configuration for such stars, the two…
Baade's window with APOGEE: Metallicities, ages and chemical abundances
M. Schultheis, A. Rojas-Arriagada, A. E. García Pérez +23
Baade's window (BW) is one of the most observed Galactic bulge fields in terms of chemical abundances. Due to its low and homogeneous interstellar absorption it is considered as a…
SDSS-IV MaNGA: The Impact of Diffuse Ionized Gas on Emission-line Ratios, Interpretation of Diagnostic Diagrams, and Gas Metallicity Measurements
Kai Zhang, Renbin Yan, Kevin Bundy +24
Diffuse Ionized Gas (DIG) is prevalent in star-forming galaxies. Using a sample of 365 nearly face-on star-forming galaxies observed by MaNGA, we demonstrate how DIG in star-formin…
