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 Enigmatic compact radio source coincident with the energetic X-ray pulsar PSR J18131749 and HESS J1813178
Sergio A. Dzib, Luis F. Rodríguez, Ramesh Karupussamy +2
New VLA detections of the variable radio continuum source VLA J181335.1174957, associated with the energetic X-ray pulsar PSR~J18131749 and the TeV source HESS J1813-178, are…
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…
A revised distance to IRAS 162932422 from VLBA astrometry of associated water masers
S. A. Dzib, G. N. Ortiz-León, A. Hernández-Gómez +6
IRAS 16293-2422 is a very well studied young stellar system seen in projection towards the L1689N cloud in the Ophiuchus complex. However, its distance is still uncertain with a ra…
