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...
An international team of astronomers within the Araucaria Project measured the distance to the Large Magellanic Cloud (LMC) with an exceptional accuracy of 1%.
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.
LMC distance determined with the accuracy of 2% using binary systems composed of giants.
First determination of the projection factor from the analysis of a eclipsing binary system OGLE-LMC-CEP-0227.
Very precise mass determination of the Cepheid OGLE-LMC-CEP-1812 in an eclipsing binary system.
