15th Würzburg workshop on Astrophysics 2020 at HITS

Due to the COVID-19 pandemic, the annual winter workshop organized by the Physics of Stellar Objects (PSO) group at HITS had to take place as an online event. Despite its disadvantages for discussions, this format allowed for more participants in the “15th Würzburg Workshop” than in previous years and for a program that extended over the full week from 14-18 December 2020. The international group of about 50 participants involving scientists from Australia, China, Sweden, the United Kingdom, Ireland, the United States, and several institutions in Germany discussed topics in supernova research, binary stellar evolution, asteroseismology, and processes in stellar interiors. The plenary session featured invited talks by Sherry Suyu (MPA Garching, Germany) on gravitationally lensed supernovae, Zhengwei Liu (Yunnan Observatories of the Chinese Academy of Sciences, Yunnan, China) on the impact of supernova explosions on companion stars, Saskia Hekker (HITS, Heidelberg, Germany) on asteroseismology, Johann Higl (HITS Heidelberg, Germany) on compressible simulations of stellar oscillations, Mark Magee (Trinity College Dublin, Ireland) on light curves of Type Ia supernovae, and Patrick Ondratschek (MPS Göttingen, Germany) on magnetohydrodynamic simulations of common envelope phases in stellar binary systems. It was followed by topical sessions in which the participants presented their latest results and projects for collaborations were discussed.
