SUMMARY:Constraining planet populations through debris disc morphology wit
 h JWST and astrometric accelerations - Raphael Bendahan-West (Exeter)

DESCRIPTION:Despite the discovery of thousands of exoplanets in the innerm
 ost regions of planetary systems\, planets at 10s of au remain poorly cons
 trained\, with their existence often inferred from the presence of planeta
 ry material in the form of debris discs. JWST's sensitivity\, combined wit
 h detailed analysis of debris disc morphology\, presents an exciting oppor
 tunity to study these outer populations and test our understanding of plan
 etary system architecture. In this talk\, I will present the results from 
 three JWST programs targeting giant planets in systems with well-resolved 
 debris disc substructures and astrometric accelerations\, both evidence of
  planetary influence. By investigating planet-disc interactions and using 
 observational upper limits\, I will demonstrate how stringent constraints 
 can be set on the population of planets in these systems\, allowing for th
 e testing of planet formation theories.\n\n
