A bold hypothesis that outliers above the period-luminosity relation of Classical Cepheids are binaries brings a discovery of 16 new binary Cepheids with giant companions in the LMC.
Today we are celebrating with our colleague Darek Graczyk, who obtained the title of doctor habilitated!
An international team of astronomers within the Araucaria Project measured the distance to the Large Magellanic Cloud (LMC) with an exceptional accuracy of 1%.
We present analysis of eclipsing binary star LL Aqr which contains a solar twin component.
We present the results of a study of the type II Cepheid in the eclipsing binary system OGLE-LMC-T2CEP-098.
Synthetic simulation of low-mass binary stars shows that 5% of them can cross the instability strip as Binary Evolution Pulsators (BEPs).
Precise mass determination for a classical Cepheid in the double-lined, highly eccentric eclipsing binary system OGLE-LMC562.05.9009.
First determination of the mass and the projection factor for the first-overtone Cepheid OGLE-LMC-CEP-2532 in a binary system.
Binary system OGLE-LMC-CEP-1718 composed of two classical FO Cepheids confirmed spectroscopically and analized.
LMC distance determined with the accuracy of 2% using binary systems composed of giants.
