Araucaria is on YouTube! And we start with this amazing timelapse from Cerro Tololo Observatory. Available in English and in Polish. Enjoy!
ERC grant
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.
Occurrence of BEPs
Synthetic simulation of low-mass binary stars shows that 5% of them can cross the instability strip as Binary Evolution Pulsators (BEPs).
Mass determination for classical FU Cepheid
Precise mass determination for a classical Cepheid in the double-lined, highly eccentric eclipsing binary system OGLE-LMC562.05.9009
Distance to Carina dwarf galaxy
Carina distance from near-infrared photometry of RR Lyrae stars.
First-overtone Cepheid mass determination
First determination of the mass and the projection factor for the first-overtone Cepheid OGLE-LMC-CEP-2532 in a binary system.
