LL Aqr
We present analysis of eclipsing binary star LL Aqr which contains a solar twin component.
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.
Distance to the LMC
LMC distance determined with the accuracy of 2% using binary systems composed of giants.
