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%.
The Araucaria Meeting is a biennial event that brings together 24 astronomers from Poland, France, Italy, Germany, the USA, and Chile, who work on the calibration of the cosmic distance scale and related topics....
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.
Applications are invited for one postdoctoral position at the Nicolaus Copernicus Astronomical Center (NCAC), in Warsaw, Poland, in the field of extragalactic distance scale. The successful applicant will work with Prof. Grzegorz Pietrzyński on...
With great sadness we inform that the Araucaria’s member, Zbigniew Kołaczkowski, passed away on September 22, 2018. Zbigniew joined the Araucaria Project in 2017, bringing to the team his knowledge of variable stars and...
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.
Before we start an observing night, twice a year we get to see this gem: a marvelous sunset captured from Cerro Armazones of the setting Sun, that illuminates four Unit Telescopes of Very Large...
We present analysis of eclipsing binary star LL Aqr which contains a solar twin component.
