Multiplicity of Galactic Cepheids from long-baseline interferometry. IV. New detected companions from MIRC and PIONIER observations

A. Gallenne, P. Kervella, S. Borgniet +10

We aim at detecting and characterizing the main-sequence companions of a sample of known and suspected Galactic binary Cepheids. We used the multi-telescope interferometric combine…

Metallicity estimates of young clusters in the Magellanic Clouds from Stromgren photometry of supergiant stars

A. E. Piatti, G. Pietrzyński, W. Narloch +2

We present results obtained from Stromgren photometry of 13 young (~30-220 Myr) Magellanic Cloud (MC) clusters, most of them lacking in the literature from direct metallicity measu…

The Araucaria Project. Multi-band calibrations of the TRGB absolute magnitude

Marek Górski, Grzegorz Pietrzyński, Wolfgang Gieren +10

We present new empirical calibrations of the absolute magnitude of the tip of the red giant branch (TRGB) in the optical I and near-infrared J, H, and K bands in terms of the (V-K)…

The dynamical mass and evolutionary status of the type-II Cepheid in the eclipsing binary system OGLE-LMC-T2CEP-211 with a double-ring disk

Bogumił Pilecki, Ahmet Dervişoğlu, Wolfgang Gieren +5

We present the analysis of a peculiar W~Virginis (pWVir) type-II Cepheid, OGLE-LMC-T2CEP-211 (), in a double-lined binary system (), which shed l…

A geometrical 1% distance to the short-period binary Cepheid V1334 Cygni

A. Gallenne, P. Kervella, N. R. Evans +18

Cepheid stars play a considerable role as extragalactic distances indicators, thanks to the simple empirical relation between their pulsation period and their luminosity. They over…

The effect of metallicity on Cepheid Period-Luminosity relations from a Baade-Wesselink analysis of Cepheids in the Milky Way and Magellanic Clouds

W. Gieren, J. Storm, P. Konorski +14

The extragalactic distance scale builds on the Cepheid period-luminosity (PL) relation. In this paper, we want to carry out a strictly differential comparison of the absolute PL re…
