New Near-Infrared Period-Luminosity-Metallicity Relations for Galactic RR Lyrae Stars Based on Gaia EDR3 Parallaxes
Bartłomiej Zgirski, Grzegorz Pietrzyński, Marek Górski +13
We present new period-luminosity and period-luminosity-metallicity relations for Galactic RR Lyrae stars based on a sample of 28 pulsators located at distances up to kpc from…
Synthetic Population of Binary Cepheids. II. The effect of companion light on the extragalactic distance scale
Paulina Karczmarek, Gergely Hajdu, Grzegorz Pietrzyński +5
Because of their period-luminosity relation (PLR), classical Cepheids play a key role in the calibration of the extragalactic distance scale and the determination of the Hubble-Lem…
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…
