Kuiper Belts around other stars
Guest Speaker
Thursday, 22nd October 2026 (19:45 - 22:00)
Venue: Hybrid
Dive into the mysteries of distant solar systems and discover what those icy Kuiper Belts are hiding beyond our own backyard.
Our Solar System contains not only planets, but also many smaller bodies like asteroids and comets. These bodies are collectively called 'debris', and they tend to be concentrated in 'debris discs' like the Asteroid Belt and Kuiper Belt. We can image debris discs like the Kuiper Belt around other stars too, and these discs show a broad range of shapes and features. These features are often thought to be caused by unseen exoplanets. In this talk we look at a broad overview of Kuiper Belts around other stars, including what they look like, how they evolve, and what they teach us about exoplanets and planetary systems. For this talk I assume no prior knowledge, and try to make it accessible to a wide range of seniorities and experience levels.

Speaker: Tim Pearce
Tim Pearce is a Stephen Hawking Fellow at the University of Warwick. He mainly research 'debris discs', around other stars, which are populations of asteroids and comets like the Asteroid Belt and Kuiper Belt in our Solar System. He is particularly interested in how exoplanets interact with debris. His work is mainly theory, but he is also very involved in observations using the James Webb Space Telescope, ALMA and the VLTI.
He completed a Master's degree at Durham and a PhD at Cambridge, then left academia and was selected to be an officer in the Royal Navy, where he specialised in engineering aboard nuclear submarines. He then became Lead Mathematical Developer at leading traffic-modelling company, before returning to academia in December 2019 as a postdoctoral researcher in Jena, Germany. He joined Warwick in Nov 2023 as a Warwick Prize Fellow, and became a Stephen Hawking Fellow in May 2024. At the time of this talk Tim may have moved to Trinity College Dublin as an Assistant Professor.
