The Oph region revisited with Gaia EDR3
Natalie Grasser, Sebastian Ratzenböck, João Alves +10
Context. Young and embedded stellar populations are important probes of the star formation process. Paradoxically, we have a better census of nearby embedded young populations than…
Evidence for Radial Expansion at the Core of the Orion Complex with Gaia EDR3
Cameren Swiggum, Elena D'Onghia, João Alves +6
We present a phase-space study of two stellar groups located at the core of the Orion complex: Briceño-1 and Orion Belt Population-near (OBP-near). We identify the groups with the…
3D dynamics of the Orion cloud complex -- Discovery of coherent radial gas motions at the 100-pc scale
Josefa E. Großschedl, João Alves, Stefan Meingast +1
We present the first study of the 3D dynamics of the gas in the entire southern Orion cloud complex. We used the parallaxes and proper motions of YSOs from Gaia DR2 as a proxy for…
3D shape of Orion A with Gaia DR2. An informed view on Star Formation Rates and Efficiencies
Josefa E. Großschedl, João Alves, Stefan Meingast +1
The giant molecular cloud Orion A is the closest massive star-forming region to earth ( pc). It contains the rich Orion Nebula Cluster (ONC) in the North, and low-mass st…
VISION - Vienna survey in Orion. III. Young stellar objects in Orion A
Josefa E. Großschedl, João Alves, Paula S. Teixeira +14
We have extended and refined the existing young stellar object (YSO) catalogs for the Orion A molecular cloud, the closest massive star-forming region to Earth. This updated catalo…
3D shape of Orion A from Gaia DR2
Josefa E. Grossschedl, Joao Alves, Stefan Meingast +16
We use the DR2 distances of about 700 mid-infrared selected young stellar objects in the benchmark giant molecular cloud Orion A to infer its 3D shape and orientati…
