"How to form scaled down Solar Systems?"

NASA’s Transiting Exoplanet Survey Satellite (TESS) is the first all-sky space-based transiting planet survey mission. Using its full-sky observations, we have been able to discover and characterise some rare planet populations. These include the "scaled down" Solar Systems – multiplanetary systems with Jovian planets and Super Earths orbiting closely to their host stars. Understanding the formation of these planetary systems will be the first step towards placing the Solar System amongst the exoplanets. I have been using a new generation of ground and space based telescopes to examine their atmospheres, interiors, and population statistics. I will describe our JWST program aimed at examining the formation routes of one such exemplary system in exquisite detail. In the next five years, we look towards the full data release from the Gaia mission that will enable us to extend our knowledge to planets with orbital periods more comparable to the Solar System planets.
