SUMMARY:How massive are exo-Kuiper Belts? - Dr Tim Pearce (Warwick)
DTSTART:20251113T133000Z

UID:TALK240205@talks.cam.ac.uk
CONTACT:James Rogers
DESCRIPTION:Our Solar System contains many small objects\, such as asteroi
 ds and comets\, which are mainly concentrated in the Asteroid and Kuiper B
 elts. Other stars have similar belts\, which appear to be fundamental comp
 onents of planetary systems. Many extrasolar belts are much brighter than 
 those in the Solar System\, and they have a diverse range of shapes and st
 ructures\, which may be indicative of planetary interactions. However\, th
 ere is a key gap in our knowledge: we do not know how massive extrasolar b
 elts are. This is important\, because belt masses have significant implica
 tions for the formation\, evolution and architectures of planetary systems
 . In this talk\, I describe our current efforts to dynamically weigh exo-K
 uiper Belts\, using new techniques and observations. These methods have no
 t been implemented before\, but show promise for finally constraining belt
  masses. I will also discuss the science that would open up if we could we
 igh these belts\, and what this could mean for future theory and observati
 ons. For this talk I assume no prior knowledge\, and the talk should be ac
 cessible to a wide range of seniorities and experience levels.
