Pulsation periods reveal tension between theoretical and empirical radii for classical Cepheids in eclipsing binary systems
O. Ziółkowska, R. Smolec, R. Singh Rathour +1
Context. With their precisely determined physical parameters, classical Cepheids in eclipsing binary systems are often used to constrain stellar evolution and pulsation theories. T…
Toward a Comprehensive Grid of Cepheid Models with MESA. IV. Modest Effects of Rotation on Blue Loops
R. Smolec, R. Singh Rathour, V. Hocdé
Evolutionary tracks for stars, with metallicities of , , and , including rotation, are computed with Modules for Experiments in Stellar Astrophy…
V446 Cephei: a Cep pulsator in a multiple system
A. Moharana, J. Southworth, K. Pavlovski +7
Cep stars in eclipsing binary (EB) systems give us an opportunity to put observational constraints on their structure and stellar parameters. We present a comprehensive analys…
Toward a Comprehensive Grid of Cepheid Models with MESA. III. Evolutionary and Pulsation Relations for Models with Core and Envelope Overshooting
R. Smolec, O. ZióÅkowska, R. Singh Rathour +2
Evolutionary tracks for 2-8M models, covering a [Fe/H]=1.0 () to [Fe/H]=+0.2 () metallicity range are computed with Modules for Experiments in Stellar…
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…
Toward a Comprehensive Grid of Cepheid Models with MESA II. Impact of Physical and Numerical Assumptions on Elemental Abundances
O. ZióÅkowska, R. Smolec, A. Thoul +2
Modern tools for modeling stellar evolution, such as MESA (Modules for Experiments in Stellar Astrophysics), offer state-of-the-art implementations of stellar theories. However, th…
