Discovery of a binary-origin classical Cepheid in a binary system with a 59-day orbital period
Bogumił Pilecki, Ian B. Thompson, Felipe Espinoza-Arancibia +8
We report the discovery of a surprising binary configuration of the double-mode Cepheid OGLE-LMC-CEP-1347 pulsating in the first (P_1=0.690d) and second overtone (P_2=0.556d) modes…
Evolved eclipsing binary systems in the Galactic bulge: Precise physical and orbital parameters of OGLE-BLG-ECL-305487 and OGLE-BLG-ECL-116218
K. Suchomska, D. Graczyk, C. Gałan +17
Our goal is to determine, with high accuracy, the physical and orbital parameters of two double-lined eclipsing binary systems, where the components are two giant stars. We also ai…
The binary system of the spinning-top Be star Achernar
P. Kervella, S. Borgniet, A. Domiciano de Souza +16
Achernar, the closest and brightest classical Be star, presents rotational flattening, gravity darkening, occasional emission lines due to a gaseous disk, and an extended polar win…
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…
Metallicities and ages for star clusters and their surrounding fields in the Large Magellanic Cloud
W. Narloch, G. Pietrzyński, W. Gieren +15
We study 147 star clusters in the Large Magellanic Cloud (LMC) in order to determine their mean metallicities and ages, as well as the mean metallicities of 80 surrounding fields.…
