Exploring the Full Stellar Population of the Upper Scorpius OB Association
- T. Preibisch, A. Brown, T. Bridges, E. Guenther, H. Zinnecker
- Physics
- 1 July 2002
We investigate the stellar population and star formation history of the Upper Scorpius OB association, the most nearby region of recent massive star formation, over the full stellar mass range from… Expand
Toward Understanding Massive Star Formation
- H. Zinnecker, H. Yorke
- Physics
- 9 July 2007
AbstractAlthough fundamental for astrophysics, the processes that produce massive stars are not well understood. Large distances, high extinction, and short timescales of critical evolutionary phases… Expand

Low-mass star formation in the upper Scorpius OB association.
- T. Preibisch, H. Zinnecker, E. Guenther, M. Sterzik, S. Frink, S. Roeser
- Physics
- 1 May 1999
We use a large sample of about 100 low-mass pre–main-sequence (PMS) stars in the Upper Scorpius OB association to explore the star formation history and the initial mass function of this association.… Expand
X-Ray Properties of the Young Stellar and Substellar Objects in the IC 348 Cluster: The Chandra View
- T. Preibisch, H. Zinnecker
- Physics
- 1 March 2002
We explore the X-ray properties of the young stellar and substellar objects in the open cluster IC 348 as seen in our deep Chandra X-Ray Observatory Advanced CCD Imaging Spectrometer image. First, we… Expand

Aims. This paper describes a systematic search for high-order multiplicity among wide visual Pre-Main Sequence (PMS) binaries. Methods. We conducted an Adaptive Optics survey of a sample of 58 PMS… Expand
SOUTHERN MASSIVE STARS AT HIGH ANGULAR RESOLUTION: OBSERVATIONAL CAMPAIGN AND COMPANION DETECTION
- H. Sana, J. Bouquin, +12 authors H. Zinnecker
- Physics
- 22 September 2014
Multiplicity is one of the most fundamental observable properties of massive O-type stars and offers a promising way to discriminate between massive star formation theories. Nevertheless, companions… Expand
