New nearby white dwarfs from Gaia DR1 TGAS and UCAC5/URAT
Ralf-Dieter Scholz, Helmut Meusinger, Hartmut Jahreiß
Using an accurate Gaia TGAS 25pc sample, nearly complete for GK stars, and selecting common proper motion (CPM) candidates from UCAC5, we search for new white dwarf (WD) companions…
A preliminary comparison of photometric (MWSC) and trigonometric (TGAS) distances of open cluster stars
Dana Kovaleva, Anatoly Piskunov, Nina Kharchenko +1
Our goal was to compare the open cluster photometric distance scale of the global survey of star clusters in the Milky Way (MWSC) with the distances derived from trigonometric para…
Open star clusters in the Milky Way - Comparison of photometric and trigonometric distance scales based on Gaia TGAS data
Dana A. Kovaleva, Anatoly E. Piskunov, Nina V. Kharchenko +5
The global survey of star clusters in the Milky Way (MWSC) is a comprehensive list of 3061 objects that provides, among other parameters, distances to clusters based on isochrone f…
Magnetic field geometry and chemical abundance distribution of the He-strong star CPD -57 3509
S. Hubrig, N. Przybilla, H. Korhonen +9
The magnetic field of CPD -57 3509 was recently detected in the framework of the BOB (B fields in OB stars) collaboration. We acquired low-resolution spectropolarimetric observatio…
An astrometric and spectroscopic study of the Scuti variable HD21190 and its wide companion CPD -83 64B
E. Niemczura, R. -D. Scholz, S. Hubrig +4
Although pulsations of Scuti type are not expected among Ap stars from a theoretical point of view, previous observations of the known Scuti star HD21190 indicated a spectr…
Rotationally modulated variability and pulsations of the He-rich star CPD -62 2124 with an extraordinarily strong magnetic field
S. Hubrig, Z. Mikulasek, A. F. Kholtygin +5
A longitudinal magnetic field with a strength of 5.2kG was recently detected in CPD -62 2124, which has a fractional main-sequence lifetime of about 60%. Strongly magnetic early-B…
