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 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…
