Gaia-DR2 confirms VLBA parallaxes in Ophiuchus, Serpens and Aquila
Gisela N. Ortiz-León, Laurent Loinard, Sergio A. Dzib +9
We present Gaia-DR2 astrometry of a sample of YSO candidates in Ophiuchus, Serpens Main and Serpens South/W40 in the Aquila Rift, which had been mainly identified by their infrared…
The Gould's Belt Distances Survey (GOBELINS). V. Distances and Kinematics of the Perseus molecular cloud
Gisela N. Ortiz-León, Laurent Loinard, Sergio A. Dzib +10
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 of the GO…
44 New & Known M Dwarf Multiples In The SDSS-III/APOGEE M Dwarf Ancillary Science Sample
Jacob Skinner, Kevin R. Covey, Chad F. Bender +28
Binary stars make up a significant portion of all stellar systems. Consequently, an understanding of the bulk properties of binary stars is necessary for a full picture of star for…
The APOGEE-2 Survey of the Orion Star Forming Complex II: Six-dimensional structure
Marina Kounkel, Kevin Covey, Genaro Suárez +17
We present an analysis of spectrosopic and astrometric data from APOGEE-2 and Gaia DR2 to identify structures towards the Orion Complex. By applying a hierarchical clustering algor…
The Gould's Belt Distances Survey (GOBELINS). IV. Distance, Depth and Kinematics of the Taurus Star-Forming Region
Phillip A. B. Galli, Laurent Loinard, Gisela N. Ortiz-Leon +13
We present new trigonometric parallaxes and proper motions of young stellar objects in the Taurus molecular cloud complex from observations collected with the Very Long Baseline Ar…
The APOGEE-2 Survey of the Orion Star Forming Complex: I. Target Selection and Validation with early observations
J'Neil Cottle, Kevin R. Covey, Genaro Suárez +26
The Orion Star Forming Complex (OSFC) is a central target for the APOGEE-2 Young Cluster Survey. Existing membership catalogs span limited portions of the OSFC, reflecting the diff…
