New paper by our (former) postdoc Diego Calderón in collaboration with colleagues from the USA. Radiation hydrodynamics simulations of complicated structures in tidal disruption events. Paper available on astro-ph.
Our group had a strong presence at the EAS meeting in Krakow, where Jakub Cehula, Damien Gagnier, Milan Pešta, and Ondřej Pejcha presented talks. It was great meeting old friends, making new, and learning about exciting science.
Camille Landri is spending 6 weeks this summer attending the Kavli Summer Program on Astrophysics: The lives, deaths and afterlives of interacting stars. After the first week of lectures, she is busy working on numerical project on common envelope evolution.
Anthony Kirilov spent entire May visiting the group of Prof. Rosswog at Hamburg Observatory, where he continued working on radiation hydrodynamics with our former postdoc Diego Calderón.
Damien Gagnier flew across the pond to present talk at the Athena++ workshop at the Center for Computational Astrophysics in New York.
In late March, I toured couple institutions in the MidWest and East Coast USA. I started for a couple days at the Ohio State University, where Jakub Cehula is temporarily working on a side project. Then, I gave a seminar at Purdue, colloquium at Penn State, and presentation at Center for Computational Astrophysics. I finished the trip with a TDE workshop at Columbia.
In his first astronomy paper, PhD student Jakub Cehula looks at how is mass transfer in binary stars calculated in 1D stellar evolution codes. These codes work and produce binary evolutionary tracks so why look at this?Continue reading “A theory of mass transfer in binary stars”
