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…
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…
Non-linear dense core formation in the dark cloud L1517
Stefan Heigl, Andreas Burkert, Alvaro Hacar
We present a solution for the observed core fragmentation of filaments in the Taurus L1517 dark cloud which previously could not be explained (Hacar et. al 2011). Core fragmentatio…
