JWST | How do planetary systems form and evolve?

Olivier Absil JWST

Interview with Olivier Absil, astrophysicist, FNRS Senior Research associate,  Head of the PSILab (Planetary and Stellar systems Imaging Laboratory) at the STAR Institute of the University of Liege.

What are the great mysteries of the universe that astrophysicists hope to unravel with JWST? What science project(s) based on JWST data are you involved in? What do they consist of? One of your projects will focus on the study of giant exoplanets located far from their star, objects that are generally less known. What is the interest of these new targets? What can they teach us? What imaging methods will you use, and with which JWST instrument? What is a circumstellar disk? What does this object bring as information on the formation of planets and our universe? You already work with data from many ground-based telescopes (VLT in particular). What data will JWST be able to detect that ground-based observatories (and other space-based telescopes) cannot? How will the JWST targets be defined? Is it the ground-based telescopes that will guide the choice of what will be observed by JWST? Does the JWST have the capacity to image potentially habitable planets?
