A new compact young moving group around V1062 Sco
Siegfried Röser, Elena Schilbach, Bertrand Goldman +3
Aims. We are searching for new open clusters or moving groups in the Solar neighbourhood. Methods. We used the Gaia-TGAS catalogue, cut it into narrow proper motion and parallax sl…
Pan-STARRS Photometric and Astrometric Calibration
Eugene. A. Magnier, Edward. F. Schlafly, Douglas P. Finkbeiner +18
We present the details of the photometric and astrometric calibration of the Pan-STARRS1 Survey. The photometric goals were to reduce the systematic effects introduced by the…
Calibration of stellar and atmospheric models using the Hyades
Taisiya G. Kopytova, Wolfgang Brandner, Siegfried Röser +2
Calibration and benchmarking of evolutionary and atmospheric models is essential for the study of low-mass stars and brown dwarfs, as for isolated objects these models are the only…
Spectroscopic and photometric studies of white dwarfs in the Hyades
P. -E. Tremblay, E. Schilbach, S. Röser +3
The Hyades cluster is known to harbour ten so-called classical white dwarf members. Numerous studies through the years have predicted that more than twice this amount of degenerate…
New white dwarfs in the Hyades --Results from kinematic and photometric studies
Elena Schilbach, Siegfried Roeser
On the basis of the PPMXL catalogue (Röser, Demleitner & Schilbach, 2010) we searched for white dwarfs that are also member candidates of the Hyades in a region up to 40 pc from th…
4U 1907+09: a HMXB running away from the Galactic plane
V. V. Gvaramadze, S. Roeser, R. -D. Scholz +1
We report the discovery of a bow shock around the high-mass X-ray binary (HMXB) 4U 1907+09 using the Spitzer Space Telescope 24 m data (after Vela X-1 the second example of bow…
Open clusters and the galactic disk
Siegfried Roeser, Nina V. Kharchenko, Anatoly E. Piskunov +3
It is textbook knowledge that open clusters are conspicuous members of the thin disk of our Galaxy, but their role as contributors to the stellar population of the disk was regarde…
Astrophysical supplements to the ASCC-2.5. Ia. Radial velocities of about 55000 stars and mean radial velocities of 516 Galactic open clusters and associations
N. V. Kharchenko, R. -D. Scholz, A. E. Piskunov +2
We present the 2nd version of the Catalogue of Radial Velocities with Astrometric Data (CRVAD-2). This is the result of the cross-identification of stars from the All-Sky Compiled…
A Strategy for Identifying the Grid Stars for the Space Interferometry Mission (SIM)
Sabine Frink, Andreas Quirrenbach, Debra Fischer +2
We present a strategy to identify several thousand stars that are astrometrically stable at the micro-arcsecond level for use in the SIM (Space Interferometry Mission) astrometric…
