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...
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.
We present the results of a study of the type II Cepheid in the eclipsing binary system OGLE-LMC-T2CEP-098.
We are delighted to present to you our new member Zbigniew Kołaczkowski.
Araucaria is on YouTube! And we start with this amazing timelapse from Cerro Tololo Observatory. Available in English and in Polish. Enjoy!
Professor Grzegorz Pietrzyński has received European Research Council Advanced grant of 2.4 million Euro for “A sub-percent distance scale from binaries and Cepheids” project.
Synthetic simulation of low-mass binary stars shows that 5% of them can cross the instability strip as Binary Evolution Pulsators (BEPs).
