An international team of astronomers within the Araucaria Project measured the distance to the Large Magellanic Cloud (LMC) with an exceptional accuracy of 1%.

Measurements of parallaxes of 81 detached eclipsing binary stars in the Milky Way allowed for the determination of the global zero-point shift in the Gaia Data Release 2 (DR2) parallaxes.
Metallicity is a vital parameter that impacts classical Cepheids’ luminosities. In all observed bands, metal-poor Cepheids in the SMC are intrinsically fainter than their more metal-rich counterparts in the LMC and MW.
Based on new observations and improved modeling techniques, we have re-analyzed seven Cepheids in the Large Magellanic Cloud.
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
Carina distance from near-infrared photometry of RR Lyrae stars.
First determination of the mass and the projection factor for the first-overtone Cepheid OGLE-LMC-CEP-2532 in a binary system.
