NIR proper motion catalogue from UKIDSS-LAS
The United Kingdom Infrared Deep Sky Survey (UKIDSS) Large Area Survey (LAS) began in 2005, with the start of the UKIDSS programme as a 7 year effort to survey roughly... -
Properties of field RR Lyrae variables
We use accurate absolute UCAC4 proper motions, V-band photoelectric and CCD photometry including our own and compiled data, WISE W1-band mid-IR photometry, as well as extensive... -
USco ZYJHK1K2 photometry and proper motions
We present the results of a deep ZYJ near-infrared survey of 13.5deg^2^ in the Upper Scorpius (USco) OB association. We photometrically selected ~100 cluster member candidates... -
Catalogue of bright (K<9) M dwarfs
Using the Position and Proper Motion Extended-L (PPMXL) catalogue, we have used optical and near-infrared colour cuts together with a reduced proper motion cut to find bright M... -
Masses of Praesepe members
We have determined possible cluster members of the nearby open cluster Praesepe (M44) based on J and K photometry and proper motions from the PPMXL catalogue and z photometry... -
Cepheids in open clusters
Cepheids in open clusters (cluster Cepheids: CCs) are of great importance as zero-point calibrators of the Galactic Cepheid period-luminosity relationship (PLR). We perform an... -
UKIDSS GCS Upper Sco members
We present the results of a proper motion wide-field near-infrared survey of the entire Upper Sco (USco) association (about 160 square degrees) released as part of the UKIRT... -
Proper motions and membership in NGC 3766
Relative proper motions (PMs) and cluster membership probabilities (P_mu_) were derived for ~2500 stars in the field of the open star cluster NGC 3766. The cluster was observed... -
UKIDSS GCS Praesepe members
Over the past decades open clusters have been the subject of many studies. Such studies are crucial considering that the universality of the initial mass function is still a... -
UKIDSS-GCS {alpha} Per members
We present the results of a deep (J=19.1mag) infrared (ZY JHK) survey over the full {alpha} Per open cluster extracted from the Data Release 9 of the United Kingdom Infrared... -
High proper-motion white dwarfs
We conducted a spectropolarimetric survey of 58 high proper-motion white dwarfs which achieved uncertainties of >~2kG in the H{alpha} line and >~5kG in the upper Balmer... -
UKIDSS Galactic Clusters Survey Pleiades members
We present the results of a deep wide-field near-infrared survey of the entire Pleiades cluster recently released as part of the UKIRT Infrared Deep Sky Survey (UKIDSS) Galactic... -
Stellar rotation in Hyades and Praesepe
We present the results of photometric surveys for stellar rotation in the Hyades and in Praesepe, using data obtained as part of the SuperWASP exoplanetary transit-search... -
Candidate subdwarfs and white dwarfs
Photometry from the Two-Micron All-Sky Survey (2MASS), United States Naval Observatory CCD Astrograph Catalog (UCAC3) and SuperCosmos catalogues, together with proper motions... -
Low-mass stars and brown dwarfs in Praesepe
Presented are the results of a large and deep optical-near-infrared multi-epoch survey of the Praesepe open star cluster using data from the UKIRT Infrared Deep Sky Survey... -
Southern ultracool dwarfs in young moving groups
We associate 132 low-mass ultracool dwarfs in the southern hemisphere as candidate members of five moving groups (MGs) using photometric and astrometric selection techniques. Of... -
Velocity and proper motion of OB associations
The proper motions of OB-associations computed using the old (1997, Cat. ) and new (2008, Cat. ) reductions of the Hipparcos data are in a good agreement with each other. The... -
Orbits of open clusters in the Galaxy
We present and analyse the kinematics and orbits for a sample of 488 open clusters (OCs) in the Galaxy. The velocity ellipsoid for our present sample is derived as... -
Galactic plane IPHAS-POSSI proper motion survey
The IPHAS-POSS-I proper motion survey combines data from the INT Photometric H{alpha} survey (Drew et al., 2005MNRAS.362..753D) with SuperCOSMOS scans of POSS-I plates (Hambly... -
Galactic RR Lyrae data
We use accurate absolute proper motions and Two-Micron All-Sky Survey Ks -band apparent magnitudes for 364 Galactic RR Lyrae variables to determine the kinematical parameters of...
