Meet the family - the catalog of known hot subdwarf stars

Gänsicke, Boris T.; Telting, John H.; Østensen, Roy H. +6 more

In preparation for the upcoming all-sky data releases of the Gaia mission, we compiled a catalog of known hot subdwarf stars and candidates drawn from the literature and yet unpublished databases. The catalog contains 5613 unique sources and provides multi-band photometry from the ultraviolet to the far infrared, ground based proper motions, class…

OB Stars and Cepheids From the Gaia TGAS Catalogue: Test of their Distances and Proper Motions

Bobylev, Vadim V.; Bajkova, Anisa T.

We consider young distant stars from the Gaia TGAS catalog. These are 250 classical Cepheids and 244 OB stars located at distances up to 4 kpc from the Sun. These stars are used to determine the Galactic rotation parameters using both trigonometric parallaxes and proper motions of the TGAS stars. In this case the considered stars have relative par…

A preliminary comparison of photometric (MWSC) and trigonometric (TGAS) distances of open cluster stars

Scholz, Ralf-Dieter; Kovaleva, Dana; Piskunov, Anatoly +1 more

The goal of this researchwas to compare the open cluster photometric distance scale of the global survey of star clusters in the MilkyWay (MWSC) with the distances derived fromtrigonometric parallaxes fromthe Gaia DR1/TGAS catalogue and to investigate towhich degree and extent both scales agree.We compared the parallax-based and photometrybased di…
