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.

Occurrence of BEPs
Synthetic simulation of low-mass binary stars shows that 5% of them can cross the instability strip as Binary Evolution Pulsators (BEPs).
Mass determination for classical FU Cepheid
Precise mass determination for a classical Cepheid in the double-lined, highly eccentric eclipsing binary system OGLE-LMC562.05.9009.
Distance to Carina dwarf galaxy
Carina distance from near-infrared photometry of RR Lyrae stars.
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.
Binary Evolution Pulsator (BEP)
New type of RR Lyrae-like variable identified in a binary system.
