Finding the elusive RR Lyrae companions via speckle imaging
R. Salinas, V. Kalari, G. Hajdu +25
Despite their key role in astrophysics, the binary properties of RR Lyrae stars (RRL) remain almost completely unknown since only a single RRL is confirmed as belonging to a binary…
Period-Luminosity Relations, projection factor and radii of Anomalous Cepheids
Piotr Wielgórski, Grzegorz Pietrzyński, Wolfgang Gieren +24
Anomalous Cepheids are radially pulsating stars observed in dwarf galaxies, the Galactic bulge and halo, and globular clusters. Similarly to other radially pulsating stars, they ca…
The Bochum Survey of the Southern Galactic Disk: III. Complete Data Release
Julia Blex, Moritz Hackstein, Christian Westhues +6
The Southern Galactic Disk Survey (GDS) monitored a mosaic of 268 fields along a -wide stripe in the southern Galactic disk with simultaneous observations in and …
The Infrared Surface Brightness technique applied to RR Lyrae stars from the solar neighborhood
Bartłomiej Zgirski, Wolfgang Gieren, Grzegorz Pietrzyński +9
The Baade-Wesselink method allows us to estimate distances to individual pulsating stars. Accurate geometric parallaxes obtained by the Gaia mission serve us in the calibration of…
Projection factor and radii of Type II Cepheids
Piotr Wielgórski, Grzegorz Pietrzyński, Wolfgang Gieren +14
Type II Cepheids are old pulsating stars that can be used to trace the distribution of an old stellar population and to measure distances to globular clusters and galaxies within s…
Surface brightness-colour relations of dwarf stars from detached eclipsing binaries -- I. Calibrating sample
D. Graczyk, G. Pietrzyński, C. Galan +19
Surface brightness -- colour relations (SBCRs) are very useful tools for predicting the angular diameters of stars. They offer the possibility to calculate very precise spectrophot…
