Period-luminosity and period-luminosity-metallicity relations for Galactic RR Lyrae stars in the Sloan bands
W. Narloch, G. Hajdu, G. Pietrzynski +6
RR Lyrae stars are excellent tracers of the old population II due to their period-luminosity (PL) and period-luminosity-metallicity (PLZ) relations. While these relations have been…
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…
The Araucaria project: High-precision orbital parallaxes and masses of binary stars. I. VLTI/GRAVITY observations of ten double-lined spectroscopic binaries
A. Gallenne, A. Mérand, P. Kervella +4
We aim to measure very precise and accurate model-independent masses and distances of detached binary stars. Precise masses at the % level are necessary to test and calibrate…
HARPS-N high spectral resolution observations of Cepheids II. The impact of the surface-brightness color relation on the Baade-Wesselink projection factor of eta Aql
N. Nardetto, W. Gieren, J. Storm +16
The Baade-Wesselink (BW) method of distance determination of Cepheids is used to calibrate the distance scale. Various versions of this method are mainly based on interferometry an…
Surface brightness-colour relations of dwarf stars from detached eclipsing binaries -- I. Calibrating sample
D. Graczyk, G. Pietrzyński, C. Galan +19
Surface brightness -- colour relations (SBCRs) are very useful tools for predicting the angular diameters of stars. They offer the possibility to calculate very precise spectrophot…
