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.
Cerro Armazones sunset
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...
LL Aqr
We present analysis of eclipsing binary star LL Aqr which contains a solar twin component.
Peculiar W Vir type Cepheid mass determination
We present the results of a study of the type II Cepheid in the eclipsing binary system OGLE-LMC-T2CEP-098.
Araucaria Meeting 2017, Kraków, Poland
We proudly present the scientific teams assembling the Araucaria Project. The Araucaria Meeting took place at the end of September 2017 in Crocow, Poland, and was attended by 23 people from 11 scientific institutions...
