Orion revisited III. The Orion Belt population
K. Kubiak, J. Alves, H. Bouy +11
This paper continues our study of the foreground population to the Orion molecular clouds. The goal is to characterize the foreground population north of NGC 1981 and to investigat…
Kompaneets Model Fitting of the Orion-Eridanus Superbubble II: Thinking Outside of Barnard's Loop
Andy Pon, Bram B. Ochsendorf, João Alves +3
The Orion star-forming region is the nearest active high-mass star-forming region and has created a large superbubble, the Orion-Eridanus superbubble. Recent work by Ochsendorf et…
Gas absorption and dust extinction towards the Orion Nebula Cluster
Birgit Hasenberger, Jan Forbrich, Joao Alves +4
We characterise the relation between the gas and dust content of the interstellar medium towards young stellar objects in the Orion Nebula Cluster. X-ray observations provide estim…
Opacity broadening and interpretation of suprathermal CO linewidths: Macroscopic Turbulence and Tangled Molecular Clouds
A. Hacar, J. Alves, A. Burkert +1
(Abridged) Many of the observed CO line profiles exhibit broad linewidths that greatly exceed the thermal broadening expected within molecular clouds. These suprathermal CO linewid…
APOGEE strings: a fossil record of the gas kinematic structure
A. Hacar, J. Alves, J. Forbrich +3
We compare APOGEE radial velocities (RVs) of young stars in the Orion A cloud with CO line gas emission and find a correlation between the two at large-scales, in agreement with pr…
VISION - Vienna survey in Orion I. VISTA Orion A Survey
Stefan Meingast, João Alves, Diego Mardones +17
Orion A hosts the nearest massive star factory, thus offering a unique opportunity to resolve the processes connected with the formation of both low- and high-mass stars. Here we p…
