Trigonometric parallaxes of ten ultracool subdwarfs
E. Schilbach, S. Roeser, R. -D. Scholz
We measured absolute trigonometric parallaxes and proper motions with respect to many background galaxies for a sample of ten ultracool subdwarfs. The observations were taken in th…
PPM-Extended (PPMX) - a catalogue of positions and proper motions
S. Roeser, E. Schilbach, H. Schwan +3
Aims: We build a catalogue PPM-Extended (PPMX) on the ICRS system which is complete down to a well-defined limiting magnitude and contains the best presently available proper motio…
On the origin of field O-type stars
E. Schilbach, S. Roeser
Aims: We try to identify the origins of field O-stars in the nearest 2 to 3 kpc around the Sun using the best presently available kinematic data on O-stars and on young open cluste…
The Radial Velocity Experiment (RAVE): first data release
M. Steinmetz, T. Zwitter, A. Siebert +51
We present the first data release of the Radial Velocity Experiment (RAVE), an ambitious spectroscopic survey to measure radial velocities and stellar atmosphere parameters (temper…
