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…
Revisiting the population of Galactic open clusters
A. E. Piskunov, N. V. Kharchenko, S. Röser +2
We present results of a study of the galactic open cluster population based on the all-sky catalogue ASCC-2.5 (I/280A) compiled from Tycho-2, Hipparcos and other catalogues. The sa…
Astrophysical parameters of Galactic open clusters
N. V. Kharchenko, A. E. Piskunov, S. Röser +2
We present a catalogue of astrophysical data of 520 Galactic open clusters. These are the clusters, for which at least three most probable members (18 on average) could be identifi…
SSSPM J1444-2019: an extremely high proper motion, ultracool subdwarf
R. -D. Scholz, N. Lodieu, M. J. McCaughrean
We present the discovery of a new extreme high proper motion object (3.5 arcsec/year) which we classify as an ultracool subdwarf with [M/H] = -0.5. It has a formal spectral type of…
SSSPMJ0829-1309: A new nearby L dwarf detected in SuperCOSMOS Sky Surveys
Ralf-Dieter Scholz, Helmut Meusinger
The SuperCOSMOS Sky Surveys provide a complete coverage of the Southern sky in three passbands (photographic B_J, R and I) and at different epochs (Hambly et al. 2001a,b,c). These…
Discovery of three nearby L dwarfs in the Southern Sky
N. Lodieu, R. -D. Scholz, M. J. McCaughrean
We report the discovery of three L dwarfs in the solar vicinity within 30 parsecs. These objects were originally found as proper motion objects from a combination of R and I photog…
