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…
Extended stellar systems in the solar neighborhood - I. The tidal tails of the Hyades
Stefan Meingast, João Alves
We report the discovery of two well-defined tidal tails emerging from the Hyades star cluster. The tails were detected in Gaia DR2 data by selecting cluster members in the three-di…
TYC 3637-1152-1 - a High Amplitude delta Scuti star with peculiar pulsational properties
Ernst Paunzen, Klaus Bernhard, Moriz Frauenberger +16
In some delta Scuti stars, only one or two radial modes are excited (usually the fundamental mode and/or first overtone mode) and the observed peak-to-peak amplitudes exceed 0.3 ma…
GD358: three decades of observations for the in-depth asteroseismology of a DBV star
Agnes Bischoff-Kim, J. L. Provencal, P. A. Bradley +38
We report on the analysis of 34 years of photometric observations of the pulsating helium atmosphere white dwarf GD358. The complete data set includes archival data from 1982-2006,…
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…
VISION - Vienna Survey in Orion II. Infrared extinction in Orion A
Stefan Meingast, João Alves, Marco Lombardi
We have investigated the shape of the extinction curve in the infrared up to ~25 μm for the Orion A star-forming complex. The basis of this work is near-infrared data acquired with…
An ALMA study of the Orion Integral Filament: I. Evidence for narrow fibers in a massive cloud
A. Hacar, M. Tafalla, J. Forbrich +4
Abridged. Are all filaments bundles of fibers? To address this question, we have investigated the gas organization within the paradigmatic Integral Shape Filament (ISF). We combine…
