Debris Disks: Planet Formation from Millions to Billions of Years
Speaker: Prof. Meredith Hughes, Wesleyan University
Abstract: Debris disks are scaled-up analogs of our own Solar System's Kuiper Belt. While protoplanetary disks probe planet-forming conditions around pre-main sequence stars, and exoplanet surveys largely probe mature planetary systems, debris disks give us insight into the liminal, adolescent stage of planetary system evolution. I will present an overview of first results from the ALMA large program ARKS: the ALMA survey to Resolve exoKuiper belt Substructures, which provides the highest-resolution mm views to date of a substantial sample of 24 debris disks around nearby young stars.
Host: Prof. Andrew Harris
