Multiplicity of Galactic Cepheids from long-baseline interferometry V. High-accuracy orbital parallax and mass of SU Cygni
A. Gallenne, N. R. Evans, P. Kervella +23
Cepheid masses are particularly necessary to help solving the mass discrepancy, while independent distance determinations provide crucial test of the period-luminosity relation and…
Precise physical parameters of three late-type eclipsing binary giant stars in the Large Magellanic Cloud
G. Rojas García, D. Graczyk, G. Pietrzyński +17
Detached eclipsing binaries (DEBs) allow for the possibility of precise characterization of its stellar components. They offer a unique opportunity to derive their physical paramet…
Fundamentalization of periods for first and second-overtone classical Cepheids
Bogumił Pilecki
Almost half of all classical Cepheids do not pulsate in fundamental mode, and nowadays, the fundamentalization of their higher-mode periods is frequently applied to increase the sa…
Projection factor and radii of Type II Cepheids
Piotr Wielgórski, Grzegorz Pietrzyński, Wolfgang Gieren +14
Type II Cepheids are old pulsating stars that can be used to trace the distribution of an old stellar population and to measure distances to globular clusters and galaxies within s…
Towards early-type eclipsing binaries as extragalactic milestones: III. Physical properties of the O-type eclipsing binary OGLE LMC-ECL-21568 in a quadruple system
Mónica Taormina, R. -P. Kudritzki, B. Pilecki +8
We present the results from a complex study of an eclipsing O-type binary (Aa+Ab) with the orbital period days, that forms part of a higher-order multiple system…
The orbital parameters of the del Cep inner binary system determined using 2019 HARPS-N spectroscopic data
N. Nardetto, V. Hocdé, P. Kervella +11
An inner companion has recently been discovered orbiting the prototype of classical Cepheids, delta Cep, whose orbital parameters are still not fully constrained. We collected new…
