Estimating distances from parallaxes. III. Distances of two million stars in the Gaia DR1 catalogue We infer distances and their asymmetric uncertainties for two million stars using the parallaxes published in the Gaia DR1 (GDR1) catalogue. We do this wit... TL Astraatmadja,Bailer-Jones, ...

HIP 4809/ A9780D Visual binaries and optical doubles A9510J Astrometry and spherical astronomy A9710R Stellar radiation and spectra A9710E Stellar atmospheres, radiative transfer, opacity, and line formation/ HIP 4809We presented a method useful for estimating parallaxes of visually close binary ...
The method is applied to preliminary parallaxes from the ESA Hipparcos mission. The formal standard errors assigned to the preliminary Hipparcos data are found to be in very good agreement with the external estimates obtained with the present method, thus confirming that most of the space parallax...
Stars: distancesParallaxesStars: statisticsA critical analysis of three methods of estimating distances to cataclysmic variables (CVs) is performed. These methods, by Ak et al., Beuermann, and Knigge, all use near-infrared ( JHK or K s) magnitudes and the Barnes鈥揈vans relation. We compare...
The SEGYE plan by SDSS involved sampling stars from different distances to capture spatial substructures in the Galactic stellar halo [1]. The Anglo-Australian Observatory utilized the Schmidt telescope to determine the radial velocity and parameters of stars [2]. LAMOST launched its low-resolution ...
