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 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…
The Araucaria Project: High-precision Cepheid astrophysics from the analysis of variables in double-lined eclipsing binaries
Bogumił Pilecki, Wolfgang Gieren, Grzegorz Pietrzyński +15
Based on new observations and improved modeling techniques, we have reanalyzed seven Cepheids in the Large Magellanic Cloud. Improved physical parameters have been determined for t…
