Even more accurate benchmark for cosmic distances
An international team of astronomers within the Araucaria Project measured the distance to the Large Magellanic Cloud (LMC) with an exceptional accuracy of 1%.
Astrophysics of Cepheids in eclipsing binary systems
Based on new observations and improved modeling techniques, we have re-analyzed seven Cepheids in the Large Magellanic Cloud.
LL Aqr – an eclipsing binary with a solar twin companion
We present analysis of eclipsing binary star LL Aqr which contains a solar twin component.
Peculiar W Vir type Cepheid mass determination
We present the results of a study of the type II Cepheid in the eclipsing binary system OGLE-LMC-T2CEP-098.
First-overtone Cepheid mass determination
First determination of the mass and the projection factor for the first-overtone Cepheid OGLE-LMC-CEP-2532 in a binary system.
Binary system of two Cepheids
Binary system OGLE-LMC-CEP-1718 composed of two classical FO Cepheids confirmed spectroscopically and analized.
Distance to the LMC
LMC distance determined with the accuracy of 2% using binary systems composed of giants.
Distance to the SMC
SMC distance determined with the accuracy of 3% using binary systems composed of giants.
First dynamical p-factor determination
First determination of the projection factor from the analysis of a eclipsing binary system OGLE-LMC-CEP-0227.
