A large moving group within the Lower Centaurus Crux association
Bertrand Goldman, Siegfried Roeser, Elena Schilbach +2
Scorpius-Centaurus is the nearest OB association and its hundreds of members were divided into sub-groups, including Lower Centaurus Crux. Here we study the dynamics of the Lower C…
Hot Stuff for One Year (HSOY) - A 583 million star proper motion catalogue derived from Gaia DR1 and PPMXL
Martin Altmann, Siegfried Roeser, Markus Demleitner +2
Recently, the first installment of data from ESA's Gaia astrometric satellite mission (Gaia-DR1) was released, containing positions of more than 1 billion stars with unprecedented…
Nine new open clusters within 500 pc from the Sun
Siegfried Roeser, Elena Schilbach, Bertrand Goldman
One of the results of the Milky Way Star Clusters (MWSC) survey by Kharchenko et al. (2013) was the detection of a slight under-density of old (ca. 1 Gyr) clusters within the neare…
A Global Correction to PPMXL Proper Motions
John J. Vickers, Siegfried Roeser, Eva K. Grebel
In this paper we notice that extragalactic sources seem to have non-zero proper motions in the PPMXL proper motion catalog. We collect a large, all-sky sample of extragalactic obje…
The RAdial Velocity Experiment (RAVE): Fourth data release
G. Kordopatis, G. Gilmore, M. Steinmetz +48
We present the stellar atmospheric parameters (effective temperature, surface gravity, overall metallicity), radial velocities, individual abundances and distances determined for 4…
A deep all-sky census of the Hyades
S. Roeser, E. Schilbach, A. E. Piskunov +2
On the basis of the PPMXL catalogue we perform an all-sky census of the Hyades down to masses of about 0.2 m_sun in a region up to 30 pc from the cluster centre. We use the proper…
