Surprising discovery of non-pulsating stars residing inside the instability of LMC Cepheids is further examined with the help of Strömgren photometry.

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).
