Period-Luminosity Relations for Galactic Type II Cepheids in the Sloan bands
W. Narloch, G. Hajdu, G. Pietrzynski +7
Type II Cepheids (T2Ceps), alongside RR Lyrae stars, serve as important distance indicators for old population II stars due to their period-luminosity (PL) relations. However, stud…

Non-evolutionary effects on period change in Magellanic Cepheids
R. S. Rathour, R. Smolec, G. Hajdu +5
Classical Cepheids are a cornerstone class of pulsators, fundamental to testing stellar evolution and pulsation theories. Their secular period changes, characterized through …

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…
