Nearest stars until 10pc
The given catalogue is a revised version of the catalogue (Zakhozhaj, 1987). The previous numeration is preserved, and the stars, with trigonometric, photometric and spectral... -
New spectral types for Tycho2 stars
We compare the spectroscopic and trigonometric parallaxes of common stars from the Tycho-2 Spectral Type and Hipparcos Catalogues. This comparison has revealed that the distance... -
Radio astrometry of MAXI J1820+070
Using the Very Long Baseline Array and the European Very Long Baseline Interferometry Network, we have made a precise measurement of the radio parallax of the black hole X-ray... -
DA and DB white dwarfs properties in Gaia DR2
We report on a comparison of spectroscopic analyses for hydrogen (DA) and helium atmosphere (DB) white dwarfs with Gaia Data Release 2 (DR2) parallaxes and photometry. We assume... -
Structure of the Upper Scorpius association
Using new proper motion data from recently published catalogs, we revisit the membership of previously identified members of the Upper Scorpius association. We confirmed 750 of... -
Kinematic analysis of M7-L8 dwarfs
We present a kinematic analysis of 152 low surface gravity M7-L8 dwarfs by adding 18 new parallaxes (including 10 for comparative field objects), 38 new radial velocities, and... -
StarCAT: STIS UV echelle spectra of stars
StarCAT is a catalog of high resolution ultraviolet spectra of objects classified as "stars," recorded by Space Telescope Imaging Spectrograph (STIS) during its initial seven... -
3D kinematic observations of stars in Galactic Centre
We present three-dimensional (3D) kinematic observations of stars within the central 0.5pc of the Milky Way (MW) nuclear star cluster (NSC) using adaptive optics imaging and... -
Improved kinematic parallaxes for Sco-Cen members
We present an analysis of the ages and star formation history of the F-type stars in the Upper Scorpius (US), Upper Centaurus-Lupus (UCL), and Lower Centaurus-Crux (LCC)... -
The California-Kepler Survey. X.
In 2017, the California-Kepler Survey (CKS) published its first data release (DR1) of high-resolution optical spectra of 1305 planet hosts. Refined CKS planet radii revealed... -
Spectrophotometric parallaxes with linear models
With contemporary infrared spectroscopic surveys like APO Galactic Evolution Experiment (APOGEE), red-giant stars can be observed to distances and extinctions at which Gaia... -
2007.5 to 2010.4 HST astrometry of HD 202206
Using Hubble Space Telescope Fine Guidance Sensor astrometry and previously published radial velocity measures, we explore the exoplanetary system HD202206. Our modeling results... -
Spectroscopy of 447 nearby M dwarfs
We present metallicities, radial velocities, and near-infrared (NIR) spectral types for 447 M dwarfs determined from moderate resolution (R{approx}2000) NIR spectra obtained... -
Spectroscopy of bright M dwarfs in the northern sky
We present a spectroscopic catalog of the 1564 brightest (J<9) M dwarf candidates in the northern sky, as selected from the SUPERBLINK proper motion catalog. Observations... -
Delta Scuti stars
An extensive and up-dated list of {delta} Sct stars is presented here. More than 500 papers, published during the last few years, have been revised and 341 new variables have... -
10 double-lined spectroscopic binaries data
We aim to measure very precise and accurate model-independent masses and distances of detached binary stars. Precise masses at the <1% level are necessary to test and... -
Astrometric Radial Velocities. III.
Astrometrically determined kinematic data are given for nearby clusters and associations, including astrometric radial velocities and kinematically improved parallaxes for... -
Spectral classification of close binaries
A sample of 135 stars with composite spectra has been observed in the near-UV spectral region with the Aurelie spectrograph at the Observatoire de Haute-Provence. Using the...
