Hunting for Exomoons with Kepler, Hubble and JWST

The seminar provides a comprehensive overview of the search for exomoons, delivered by a leading researcher in the field. Kipping’s presentation is well-structured, starting with a classification of detection methods and then focusing on transit photometry, which he convincingly argues is the most effective approach. He explains the underlying physics clearly, including the concepts of TTVs and TDVs, and illustrates them with simulations from his own code, Luna. The discussion of the Kepler-1625b candidate is balanced, presenting both supporting and opposing evidence, which demonstrates scientific rigor. The mention of JWST observations of Kepler-167e adds a timely and exciting element, showing the application of new facilities to the search. However, the talk is a seminar, not a peer-reviewed publication, and some claims are presented without detailed statistical justification. The speaker’s enthusiasm for the subject is evident, but he also acknowledges the high-risk nature of the search and the need for careful analysis. Overall, the content is scientifically sound and provides valuable insights into the current state of exomoon research, though it may be more accessible to an audience with some background in astronomy.

The title accurately reflects the content, which focuses on the search for exomoons using Kepler, Hubble, and JWST data.
