Welcome!

My name is Zdenek Prudil and I am a postdoctoral researcher at the Astronomisches Rechen-Institut in Heidelberg, Germany. I am a member of Dr. Andreas Koch's group. My research is focused on the Galactic archeology using the stellar tracers to map the spatial, dynamical, and chemical structure of the Milky Way and its neighborhood. I am also interested in studies of stellar evolution and pulsations.

Below you can find my latest research projects:

Milky Way archaeology using RR Lyrae and type II Cepheids. I. The Orphan stream in 7D using RR Lyrae stars

The first paper of the series focused on stellar structures in the Milky Way halo focuses on one of the largest Milky Way stellar streams the "Orphan" stream. In this study, we employed a probabilistic approach to identify members of the Orphan stream based on their kinematical and spatial properties. We discuss possible progenitors for the Orphan stream and we ruled out Grus II as a potential source of the Orphan stream.

Humps and bumps: The effects of shocks on the optical light curves of fundamental-mode RR Lyrae stars

The shocks in the stellar atmospheres of RR Lyrae variables have been extensively studied through spectroscopy, where they affect the line profiles in various ways. In our pilot project, we, for the first time, provide an extensive study of shock appearance in photometric light curves. Using a self-developed method, we estimated their size and compared the prominence of shocks with the physical properties of studied stars.
