(Re)Introducing MIT’s Disruptive Planets Group

I will use this first opportunity to present to the Department Lecture Series to formally introduce our research group, the Disruptive Planets Group. The Disruptive Planets Group aims at “discovering and studying new worlds to consolidate our understanding of planets and habitats”. To fulfill this mission, we focus our efforts on three general quests: (1) discovering new worlds, (2) studying atmospheres reliably, and (3) examining planet-star interactions. During this DLS, I will introduce a selected series of projects from our portfolio that showcase the progress we have made over the last two years and highlight/invite collaborations (including in the form of second generals).

The talk will include presentations of:

  • the network of SPECULOOS telescopes and the new MIT pipelines developed to discover new exoplanets and new solar-system bodies;
  • a new atmospheric retrieval framework developed to enable robust inferences despite biases and uncertainties stemming from opacity line lists;
  • updates on the characterization of the TRAPPIST-1, HD 80606, and HAT-P-2 systems;
  • the steps taken towards 3D mapping of exoplanetary atmospheres.
