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…
Distances and Kinematics of Gould Belt Star-Forming Regions with Gaia DR2 results
Sergio A. Dzib, Laurent Loinard, Gisela N. Ortiz-León +2
We present an analysis of the astrometric results from Gaia second data release (DR2) to Young Stellar Objects (YSOs) in star-forming regions related to the Gould Belt. These regio…
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…
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…
Three-dimensional structure of the Upper Scorpius association with the Gaia first data release
Phillip A. B. Galli, Isabelle Joncour, Estelle Moraux
Using new proper motion data from recently published catalogs, we revisit the membership of previously identified members of the Upper Scorpius association. We confirmed 750 of the…
