NLTE/LTE abundances of MW's thin disk CCs
Classical Cepheids (CCs) have long been considered excellent tracers of the chemical evolution of the Milky Way's young disk. We present a homogeneous, Non-Local Thermodynamical... -
Identifying open clusters members using Gaia DR3
In this study, we develop a membership identification method and apply it for 30 open clusters (OCs) within 200pc of the Sun using astrometric data of Gaia DR3. By accounting... -
Rotation-based census of blue lurkers
We have compiled a list of blue lurker (BL) candidates in open clusters using the available rotation catalogs. Blue lurkers are rejuvenated main-sequence stars hidden among... -
Galactic novae distances and properties
I derive the overall best distances for all 402 known Galactic novae, and I collect their many properties. The centrepiece is the 74 novae with accurate parallaxes from the new... -
A classifier for spurious astrometric solutions in Gaia EDR3
This table contains estimates of the "fidelity" of Gaia eDR3 astrometric solutions, a measure of the likelihood the eDR3 solution is physical rather than spurious obtained using... -
DESI DR1 redshift catalog
In 2021 May the Dark Energy Spectroscopic Instrument (DESI) collaboration began a 5-year spectroscopic redshift survey to produce a detailed map of the evolving... -
Extended Hipparcos Compilation (XHIP)
The Extended Hipparcos Compilation (XHIP) cross-references the New Hipparcos Reduction (HIP2, Cat. I/311) with relatable data from a broad survey of presently available sources.... -
Wide binaries in Tycho-Gaia: search method
We mine the Tycho-Gaia astrometric solution (TGAS) catalogue for wide stellar binaries by matching positions, proper motions and astrometric parallaxes. We separate genuine... -
Stellar twins in RAVE with Gaia
We apply the twin method to determine parallaxes to 232 545 stars of the RAVE survey using the parallaxes of Gaia DR1 as a reference. To search for twins in this large data set,... -
Gaia DR1 mass-radius relation of white dwarfs
The Gaia Data Release 1 (DR1) sample of white dwarf parallaxes is presented, including six directly observed degenerates and 46 white dwarfs in wide binaries. This data set is... -
2MASS J18212815+1414010 field stars
We used the OSIRIS camera at the 10.4m Gran Telescopio Canarias (GTC) to monitor the astrometric motion of the L4.5 dwarf 2M1821+14 over 17 months. The astrometric residuals of... -
Early-type Sco-Cen members with literature RVs
We report the serendipitous discovery of several young mid-M stars found during a search for new members of the 30-40Myr-old Octans Association. Only one of the stars may be... -
Ultracool white dwarfs
We present parallax observations and a detailed model atmosphere analysis of 54 cool and ultracool (Teff<4000K) white dwarfs (WDs) in the solar neighbourhood. For the first... -
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... -
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... -
Proper motions of pulsars
We present and analyse a catalogue of 233 pulsars with proper motion measurements. The sample contains a wide variety of pulsars including recycled objects and those associated... -
Classification of periodic variable stars from TESS
The number of known periodic variable stars has increased rapidly in recent years. As an all-sky transit survey, the Transiting Exoplanet Survey Satellite (TESS) plays an... -
Kinematics of YSOs from Gaia DR3 and APOGEE
Based on the Gaia Data Release 3 and APOGEE data sets, we investigate the kinematic differences between young stellar objects (YSOs) and their parent clouds in five nearby... -
HIP visual binaries kinematics. II.
This paper continues kinematical investigation of the Hipparcos visual binaries with known orbits. A sample, consisting of 804 binary systems with orbital elements determined... -
HIP visual binaries kinematics. I.
A sample consisting of 570 binary systems is compiled from several sources of visual binary stars with well-known orbital elements. High-precision trigonometric parallaxes (mean...
