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, BogumiÅ Pilecki, Matylda Åukaszewicz
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, BogumiÅ 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…
