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…
Period Change Rates of Large Magellanic Cloud Cepheids using MESA
F. Espinoza-Arancibia, M. Catelan, G. Hajdu +8
Pulsating stars, such as Cepheids and RR Lyrae, offer us a window to measure and study changes due to stellar evolution. In this work, we study the former by calculating a set of e…
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.…
Synthetic population of binary Cepheids. I. The effect of metallicity and initial parameter distribution on characteristics of Cepheids' companions
Paulina Karczmarek, Radosław Smolec, Gergely Hajdu +5
The majority of classical Cepheids are binary stars, yet the contribution of companions' light to the total brightness of the system has been assumed negligible and lacked a thorou…
