The Araucaria Project. The Distance to the Sculptor Group Galaxy NGC 7793 from Near-Infrared Photometry of Cepheid Variables
Bartlomiej Zgirski, Wolfgang Gieren, Grzegorz Pietrzynski +7
Following the earlier discovery of classical Cepheid variables in the Sculptor Group spiral galaxy NGC 7793 from an optical wide-field imaging survey, we have performed deep near-i…
A precision determination of the Effect of Metallicity on Cepheid absolute magnitudes in VIJHK bands from Magellanic Cloud Cepheids
Piotr Wielgorski, Grzegorz Pietrzynski, Wolfgang Gieren +8
Using high-quality observed period-luminosity relations in both Magellanic Clouds in VIJHKs bands and optical and near-infrared Wesenheit indices we determine the effect of metalli…
Mass and p-factor of the type II Cepheid OGLE-LMC-T2CEP-098 in a binary system
Bogumił Pilecki, Wolfgang Gieren, Radosław Smolec +10
We present the results of a study of the type II Cepheid () in the eclipsing binary system OGLE-LMC-T2CEP-098 (). The Cepheid belongs to the…
