Cepheids with giant companions III. Evolutionary modeling of nine binary double Cepheids from the Milky Way and Magellanic Clouds
F. Espinoza-Arancibia, B. Pilecki, M. Catelan +3
Binary double (BIND) Cepheids are systems comprising two Cepheid components. This feature provides important constraints that allow us to reveal the origin of Cepheids, trace their…
Reconstruction of Cepheid Radial Velocity Curves from the shape of the V-band Light Curves
V. Hocdé, P. Moskalik, N. Nardetto +17
This paper aims to develop the first method to reconstruct the shape of the RV curves of short-period fundamental-mode Cepheids, based exclusively on their pulsation period and the…
Empirical instability strip for classical Cepheids II. The Small Magellanic Cloud galaxy
Felipe Espinoza-Arancibia, Bogumił Pilecki, Matylda Łukaszewicz
Aims. This study aims to determine empirical intrinsic edges of the classical Cepheids instability strip (IS) in the Small Magellanic Cloud (SMC) galaxy, considering various effect…
A novel q-PED method: precise physical properties of a merger-origin binary Cepheid OGLE-LMC-CEP-1347
Felipe Espinoza-Arancibia, Bogumił Pilecki
Recently, a double-lined binary (SB2) classical Cepheid, OGLE-LMC-CEP-1347, was discovered, with the orbital period (P days) five times shorter than of any binary…
Cepheids with giant companions. II. Spectroscopic confirmation of nine new double-lined binary systems composed of two Cepheids
Bogumił Pilecki, Ian B. Thompson, Felipe Espinoza-Arancibia +13
Binary Cepheids with giant companions are crucial for studying the physical properties of Cepheid variables, providing the best means to measure their masses. Systems composed of t…
Empirical instability strip for classical Cepheids: I. The LMC galaxy
F. Espinoza-Arancibia, B. Pilecki, G. Pietrzyński +2
The instability strip (IS) of classical Cepheids has been extensively studied theoretically. Comparison of the theoretical IS edges with those obtained empirically, using the most…
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…
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…
Period Change Rates in Large Magellanic Cloud Cepheids Revisited
N. Rodríguez-Segovia, G. Hajdu, M. Catelan +10
The period-change rate (PCR) of pulsating variable stars is a useful probe of changes in their interior structure, and thus of their evolutionary stages. So far, the PCRs of Classi…
