Baade's window and APOGEE. Metallicities, ages, and chemical abundances
Context. Baade's window (BW) is one of the most observed Galactic bulge fields in terms of chemical abundances. Owing to its low and homogeneous interstellar...
BACCHUS Analysis of Weak Lines in APOGEE Spectra (BAWLAS)
Elements with weak and blended spectral features in stellar spectra are challenging to measure and require specialized analysis methods to precisely measure...
Basic parameters of three star clusters in the Small Magellanic Cloud: Kron 11, Kron 63 and NGC 121
We present observations for three star clusters, Kron 11, Kron 63 and NGC 121, in the Small Magellanic Cloud. We have studied their structure and derived their...
Binarity and the Abundance Discrepancy Problem in Planetary Nebulae
The discrepancy between abundances computed using optical recombination lines and collisionally excited lines is a major unresolved problem in nebular...
Binary central stars of planetary nebulae identified with Kepler/K2
We present the identification of 34 likely binary central stars (CSs) of planetary nebulae (PNe) from Kepler/K2 data, seven of which show eclipses. Of these, 29...
Binary Companions of Evolved Stars in APOGEE DR14: Search Method and Catalog of ∼5000 Companions
Multi-epoch radial velocity measurements of stars can be used to identify stellar, substellar, and planetary-mass companions. Even a small number of observation...
