Toward Early-type Eclipsing Binaries as Extragalactic Milestones: First Calibration of the SBCR from O- and B-type Stars in Detached Eclipsing Binaries

Mónica Taormina, G. Pietrzyński, B. Pilecki +4

To measure precise distances beyond the Magellanic Clouds and determine an accurate value of the Hubble constant, eclipsing binary systems composed of early-type stars can play a c…

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…

Toward early-type eclipsing binaries as extragalactic milestones: IV. Physical properties of three detached O/B-type systems in the LMC

Mónica Taormina, G. Pietrzyński, 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 García, D. Graczyk, G. Pietrzyński +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…
