The Infrared Surface Brightness technique applied to RR Lyrae stars from the solar neighborhood
Bartłomiej Zgirski, Wolfgang Gieren, Grzegorz Pietrzyński +9
The Baade-Wesselink method allows us to estimate distances to individual pulsating stars. Accurate geometric parallaxes obtained by the Gaia mission serve us in the calibration of…
Projection factor and radii of Type II Cepheids
Piotr Wielgórski, Grzegorz Pietrzyński, Wolfgang Gieren +14
Type II Cepheids are old pulsating stars that can be used to trace the distribution of an old stellar population and to measure distances to globular clusters and galaxies within s…
Non-evolutionary effects on period change in Magellanic Cepheids I. New binary systems revealed from Light Travel Time Effect
Rajeev Singh Rathour, Gergely Hajdu, Radosław Smolec +5
Period change studies give a window to probe into the evolution and dynamics of Cepheids. While evolutionary period changes have been well studied both observationally and theoreti…
Cepheids with giant companions. II. Spectroscopic confirmation of nine new double-lined binary systems composed of two Cepheids
Bogumił Pilecki, Ian B. Thompson, Felipe Espinoza-Arancibia +13
Binary Cepheids with giant companions are crucial for studying the physical properties of Cepheid variables, providing the best means to measure their masses. Systems composed of t…
