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