Petr Zasche

Assoc. Prof. Petr Zasche, Ph.D., is an academic at the Astronomical Institute, Faculty of Mathematics and Physics, Charles University in Prague. His research focuses on eclipsing binary stars, multiple stellar systems, and computational astrophysics, with emphasis on light-time effects, apsidal motion, and orbital dynamics. He develops specialized software for analyzing stellar systems and maintains catalogues of eclipsing-visual binaries.

Zasche's research spans observational and computational astronomy, particularly the study of complex stellar systems. Key interests include the detection and characterization of doubly eclipsing quadruple systems, orbital period variations, and the dynamics of hierarchical stellar configurations. His work often utilizes photometric data from surveys like TESS to investigate stellar parameters and orbital evolution.

Recent publications demonstrate a strong focus on multiple star systems, including discoveries of compact quadruple systems, triply eclipsing sextuples, and analyses of eccentric binaries with third-body perturbations. His articles frequently combine photometric analysis with orbital dynamics to explore stellar evolution in complex gravitational environments.

Zasche actively contributes to academic training through supervision of bachelor's theses in astronomy, pedagogical activities including specialized courses in galactic astronomy and practical astronomy, and development of observational methodologies.
