Speaker: Dr. Ingrid Pelisoli

Fantastic binaries and how to find them A large fraction of stars are in binary systems, and yet our understanding of how binarity affects stellar evolution is still fragmentary and only qualitative in many aspects. From gravitational waves to supernova Ia explosions, binary interaction plays a crucial role in our comprehension of the Universe. In order to improve our modelling of the many pathways of binary evolution, observational input is required. In this talk, I will discuss the observational signatures of binarity and its effects in stellar evolution. I will talk about current challenges in modelling binary systems and how the detailed characterisation of nearby populations can provide valuable input for theoretical models.
