The second phase of the APOGEE survey is providing near-infrared (near-IR), high-resolution, high signal-to-noise spectra of stars in the halo, disc, bar, and...
APOGEE: The Apache Point Observatory Galactic Evolution Experiment
APOGEE is a large-scale, NIR, high-resolution (R˜ 20 000) spectroscopic survey of Galactic stars. It is one of the four experiments in SDSS-III. Because APOGEE...
Apparently isolated massive stars within Galactic HII regions
The Alicante Survey of MAssive Stars in Hii Regions (A-SMASHeR) is aimed at finding the ratio of massive stars that are born in isolation. We present LIRIS/WHT...
Asteroid Lightcurves from the MOA-II Survey: a pilot study
The Microlensing Observations in Astrophysics (MOA-II) survey has performed high cadence, wide field observations of the Galactic Bulge from New Zealand since...
Astrometry with Carte du Ciel plates, San Fernando zone . II. CdC-SF: a precise proper motion catalogue
Context. The historic plates of the Carte du Ciel, an international cooperative project launched in 1887, offer valuable first-epoch material for the...
Astrometry with Carte du Ciel plates, San Fernando zone. I. Digitization and measurement using a flatbed scanner
Context: The historic plates of the Carte du Ciel, an international cooperative project launched in 1887, offers valuable first-epoch material for determining...
Context. We describe the atomic and molecular data that were used for the abundance analyses of FGK-type stars carried out within the Gaia-ESO Public...
BASS. XXV. DR2 Broad-line-based Black Hole Mass Estimates and Biases from Obscuration
We present measurements of broad emission lines and virial estimates of supermassive black hole masses (M BH) for a large sample of ultrahard X-ray-selected...
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...
