Congratulations to Jan Kříž for winning the Best student talk award at 57th Conference on Variable Star Research at Ondřejov, Czechia, with his talk titled “Coordinate Systems for the Roche Potential”!

We invite applications for postdoctoral position in the area of computational binary star astrophysics. The successful candidate will pursue original research using multi-dimensional simulations of binary stars, contribute to code development, and engage in the group’s scientific activities with optional opportunities to mentor students. Application deadline is 25 January 2026.

Congratulations to Jakub Cehula for defending his PhD thesis titled Theory of stellar mass loss: from binary stars to magnetars. Good luck in future positions at Tartu Observatory and Slovak Academy of Sciences!

I presented a poster at a meeting of German Astronomical society held at the emerging German Center for Astrophysics (DZA). It was great to see how a new astrophysics institute is established so close to Czechia and Prague.



Part of our group participated in the EAS meeting in Cork, Ireland. Jakub Cehula gave a talk and Ondřej Pejcha presented a poster. It was also great so see former students and postdocs as well as greeting old friends and meeting new ones.

It was great to visit Warsaw University Observatory after 8.5 years to give a seminar, reconnect with old friends and meet new ones.


A short but intense trip full of interesting discussions to the US Northeast to visit Center for Computational Astrophysics, Princeton University (gave a presentation at Bahcall lunch), and Brown University (discussed mathematical aspects of ERC ROGALLO).



Two-day visit at MPA Garching, where I gave SESTAS seminar on common envelope evolution. Lots of great discussions!
A short trip to Heidelberg to visit Prof. Roepke’s group working on common envelope evolution. Gave a short talk on our recent results on transients. Then on to Sofia, Bulgaria, for a business meeting of European Astronomical Society with representatives of affiliated societies.
