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…
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…
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…
High-contrast imaging of Galactic Cepheids with VLT/SPHERE
A. Gallenne, P. Kervella, N. R. Evans +10
Cepheids are key distance indicators and benchmarks for stellar evolution, yet most of them are members of binary or multiple systems. While spectroscopic surveys and Gaia proper-m…
Period-Luminosity Relations, projection factor and radii of Anomalous Cepheids
Piotr Wielgórski, Grzegorz PietrzyÅski, Wolfgang Gieren +24
Anomalous Cepheids are radially pulsating stars observed in dwarf galaxies, the Galactic bulge and halo, and globular clusters. Similarly to other radially pulsating stars, they ca…
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…
