Dying stars seeding the universe

Astrochemistry is a vibrant and interdisciplinary field that brings together astronomy, physics, and chemistry. While there is an enormous effort in understanding the chemistry of stellar birth and youth, the chemistry of stellar death is as important: the death throes of sun-like stars enrich the galaxy with fresh material to form the next generation of stars and planets by losing their outer layers by means of a gentle outflow. The presence of a companion star or planet is thought to produce intricate structures within the outflow, giving rise to the beautiful shapes of planetary nebulae, the later stage in the star’s life and an important part of Caroline Herschel’s surveys. This opens up the question of the fate of our own Solar System. To understand exactly how stars like our Sun die and how they are recycled into the next generation of stars and planets, a multidisciplinary approach is necessary, with astrochemistry playing a leading role.

About our speaker

Dr Marie Van de Sande is an Oort Fellow at Leiden Observatory at Leiden University, the Netherlands. She studies the chemistry around dying sun-like stars by developing novel chemical models and comparing their results to observations. Marie obtained her PhD in 2018 from KU Leuven (Belgium), where she stayed on as a fellow of the Research Foundation - Flanders (FWO). She moved to the University of Leeds as a Marie Skłodowska-Curie Individual Fellow in 2021 and relocated to Leiden in September 2023.
