Global survey of star clusters in the Milky Way II. The catalogue of basic parameters
Context. Although they are the main constituents of the Galactic disk population, for half of the open clusters in the Milky Way reported in the literature nothing is known except the raw position
The RAVE Survey: Constraining the Local Galactic Escape Speed
TLDR
New constraints on the local escape speed of the Galaxy are reported, finding that the escape velocity lies within the range 498 <v(esc) <608 km s (-1) (90 per cent confidence), with a median likelihood of 544 km s(-1).

Astrophysical supplements to the ASCC‐2.5: Ia. Radial velocities of ∼55000 stars and mean radial velocities of 516 Galactic open clusters and associations
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 Catalogue of 2.5
The radial velocity experiment (RAVE): First data release
TLDR
The first data release of the Radial Velocity Experiment (RAVE) is presented and it is demonstrated that the radial velocities derived for the first data set do not show any systematic trend with color or signal-to-noise ratio.
Towards absolute scales for the radii and masses of open clusters
Aims. In this paper we derive tidal radii and masses of open clusters in the nearest kiloparsecs around the Sun. Methods. For each cluster, the mass is estimated from tidal radii determined from a
A deep all-sky census of the Hyades
Aims. On the basis of the PPMXL catalogue we perform an all-sky census of the Hyades down to masses of about 0.2 m⊙ in a region up to 30 pc from the cluster centre. Methods. We use the proper motions
109 new Galactic open clusters
We present a list of 130 Galactic Open Clusters, found in the All-Sky Compiled Catalogue of 2.5 Million Stars (ASCC-2.5). For these clusters we determined a homogeneous set of astrophysical
ULAS J141623.94$ + $134836.3 - a faint common proper motion companion of a nearby L dwarf. Serendipitous discovery of a cool brown dwarf in UKIDSS DR6
Aims. New near-infrared large-area sky surveys (e.g. UKIDSS, CFBDS, WISE) go deeper than 2MASS and aim at detecting brown dwarfs lurking in the solar neighbourhood that are even fainter than the
The B-type giant HD 271791 in the Galactic halo : Linking run-away stars to hyper-velocity stars
Context. Young, massive stars have been found in the distant Galactic halo. Dynamical ejection from the Galactic disc has been suggested as the origin of these “run-away stars”. The so-called
