Reddening maps of the Magellanic Clouds
We present reddening maps of the Large and Small Magellanic Clouds, based on color measurements of the red clump stars.

Candidates for non-pulsating stars in the Cepheid instability strip
Surprising discovery of non-pulsating stars residing inside the instability of LMC Cepheids is further examined with the help of Strömgren photometry.
Habilitation title for Darek Graczyk
Today we are celebrating with our colleague Darek Graczyk, who obtained the title of doctor habilitated! Habilitation is a recognition of the contribution that Darek brought to astronomy – over the years he published...
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%.
The effect of metallicity on Cepheid period-luminosity relations
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.
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.
Distance to the LMC
LMC distance determined with the accuracy of 2% 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.
Dynamical mass of a Cepheid again
Very precise mass determination of the Cepheid OGLE-LMC-CEP-1812 in an eclipsing binary system.
Dynamical mass of a Cepheid
Very precise mass determination of the Cepheid OGLE-LMC-CEP-0227 in an eclipsing binary system.
