Toward early-type eclipsing binaries as extragalactic milestones: IV. Physical properties of three detached O/B-type systems in the LMC
Mónica Taormina, G. PietrzyÅski, R. -P. Kudritzki +10
We present a complete set of physical parameters for three early-type eclipsing binary systems in the Large Magellanic Cloud (LMC): OGLE LMC-ECL-17660, OGLE LMC-ECL-18794, and HV 2…
Precise physical parameters of three late-type eclipsing binary giant stars in the Large Magellanic Cloud
G. Rojas GarcÃa, D. Graczyk, G. PietrzyÅski +17
Detached eclipsing binaries (DEBs) allow for the possibility of precise characterization of its stellar components. They offer a unique opportunity to derive their physical paramet…
The Infrared Surface Brightness technique applied to RR Lyrae stars from the solar neighborhood
BartÅomiej Zgirski, Wolfgang Gieren, Grzegorz PietrzyÅski +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 PietrzyÅski, 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…
