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).
Speaking about measuring distances
If you understand Polish language, we have a treat for you. Araucaria starred in an episode of Astronarium series, the one about measuring distances in our Universe.
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.
Konkurs “Science is Freedom”
Prof. Grzegorz Pietrzyński, together with the Araucaria Project, was honored with 2nd price in the contest “Science is Freedom” organized by Polish Ministry of Science.
Binary system of two Cepheids
Binary system OGLE-LMC-CEP-1718 composed of two classical FO Cepheids confirmed spectroscopically and analized.
Distance to the LMC
LMC distance determined with the accuracy of 2% using binary systems composed of giants.
Distance to the SMC
SMC distance determined with the accuracy of 3% using binary systems composed of giants.
