Time-domain astronomy group at Charles University, Prague
Is there a contact binary sitting at the center of common envelope? Do we actually need magnetic fields to explain the “jets” seen in planetary nebulae? These are very exciting questions resulting from the Damien Gagnier’s third paper written during his postdoc stint in Prague.
Congratulations to Milan Pešta for winning the postdoctoral outgoing fellowship from Czech Science Foundation. Milan will spend two years at the Department of Astronomy of The Ohio State University working with Yuan-Sen Ting on machine learning and then will return for one year to our the Institute of Theoretical Physics in Prague.
I am very happy and honoured to be awarded one of ERC Consolidator grants. In the project ROGALLO we will construct new simulations of all sorts of binary stars. Thanks to all who have helped, especially students and postdocs, as well as my family for patience and support. Looking forward to what’s coming!
I am already looking for PhD students to start in Fall 2025: https://mff.cuni.cz/en/physicsphd/f1/phd-projects-funding…
The ad for two postdoc-level positions is coming as soon as the hiring is officially approved.
Congratulations to Milan Pešta on defending his PhD thesis on Illuminating binary star evolution with observed populations and theoretical modeling!
In the second week of September we participated in a conference Binary and Multiple Stars in the Era of Big Sky Surveys, which was held in Czech city of Litomyšl. Our group gave three talks (Cehula, Pejcha, Pešta) and engaged in a number of discussions.
Congratulations to Camille Landri to defending with flying colors her PhD thesis on Theory and observations of two stars undergoing strong interaction! Dr. Landri is very soon starting postdoctoral position at the Institute of Astronomy at KU Leuven. Good luck!
Damien Gagnier is leaving us after a bit more than three years in Prague. Damien is moving to start his second postdoc at Heidelberg Institute of Theoretical Studies in the group of Prof. Roepke and will continue working on simulations of common envelope evolution. Good luck in future work!
PhD student Milan Pešta submitted a paper on Distinguishing between light curves of ellipsoidal variables with massive dark companions, contact binaries, and semidetached binaries using principal component analysis. The paper is now under review in A&A.
PhD student Camille Landri submitted a paper on The Effect of Donor Star Rejuvenation on Common Envelope Evolution written together Paul Ricker, Mathieu Renzo and others. The paper is a result of Camille’s stay at Kavli summer school last year.
The recent EAS meeting in Padova, Italy, was a good opportunity to discuss new scientific collaborations with people who would be otherwise difficult to meet at one place.
