Accretion through circumstellar disks plays an important role in star formation and in
establishing the properties of the regions in which planets form and migrate. The …

We present an analysis of spectroscopic and astrometric data from APOGEE-2 and Gaia
DR2 to identify structures toward the Orion Complex. By applying a hierarchical clustering …

Abstract The Apache Point Observatory Galactic Evolution Experiment (APOGEE), one of the
programs in the Sloan Digital Sky Survey III (SDSS-III), has now completed its systematic …

ABSTRACT The Apache Point Observatory Galactic Evolution Experiment (APOGEE), part of
the Sloan Digital Sky Survey III, explores the stellar populations of the Milky Way using the …

APOGEE-2 is a high-resolution, near-infrared spectroscopic survey observing∼ 3× 10 5
stars across the entire sky. It is the successor to APOGEE and is part of the Sloan Digital Sky …

The Sloan Digital Sky Survey (SDSS; York et al. 2000) started observations in 1998 and has
completed three different phases. The data collected includes optical imaging of most of the …

APOGEE is a high-resolution (R∼ 22,000), near-infrared, multi-epoch, spectroscopic survey
of the Milky Way. The second generation of the APOGEE project, APOGEE-2, includes an …

Comprehensive wide-field imaging and spectroscopic surveys of the sky have played a key
role in astronomy, leading to fundamental new breakthroughs in our understanding of the …

ABSTRACT Young (125 Myr), populous (> 1000 members), and relatively nearby, the
Pleiades has provided an anchor for stellar angular momentum models for both younger …

We derive the distance and structure of the Perseus molecular cloud by combining
trigonometric parallaxes from Very Long Baseline Array (VLBA) observations, taken as part …
