Passing of Professor Janusz Ziółkowski (1942–2026)

 

It is with deep regret that we announce the passing of Professor Janusz Ziółkowski, an eminent Polish astrophysicist and a long-standing member of the scientific community of the Nicolaus Copernicus Astronomical Center of the Polish Academy of Sciences (CAMK PAN).

 

Professor Ziółkowski was affiliated with the Center for the majority of his academic career (1971–2016) and continued his association as Professor Emeritus from 2015. His research made significant contributions to theoretical astrophysics, particularly in the study of massive stars, binary systems, and compact objects, including neutron stars and black holes. He was highly respected both for his scientific achievements and as a mentor to generations of researchers.

 

Professor Ziółkowski will be greatly missed by our community.

 

 

The funeral will take place on April 1, 2026. A Holy Mass will be celebrated at 12:00 at the Church of Blessed Władysław of Gielniów (Przy Bażantarni Street), followed by burial at the Southern Cemetery (Cmentarz Południowy).
