From atmospheric to exoplanet formation retrievals
With new and upcoming observing facilities (JWST and the ELTs), the exoplanet community is poised to precisely measure the chemical inventory of exoplanet atmospheres. This will allow, for the first time, to start investigating whether one of the greatest promises of atmospheric characterization studies holds up: inverting the atmospheric composition ...Paul Mollière +12 more

Precision formation flying at megameter separations for exoplanet characterization
Acta Astronautica, 2016Abstract Starshade missions offer a near-term capability to measure the spectra of Earth-sized exoplanets, searching for possible bio-indicators. To function, a starshade and telescope separated by approximately 50 Mm must align to the meter-level on the line to the target star.

Close-Orbiting Exoplanets: Formation, Migration Mechanisms and Properties
2008The discovery of a signal from a putative extra-solar planet around the nearby Sun-like star 51 Peg by Mayor & Queloz and the rapid confirmation by Marcy & Butler was the main starting point for the field of extrasolar planets. More than a decade later, ‘51 Peg - type planets’ or ‘hot Jupiters’ are frequently discovered and characterised by a variety ...

Connecting the Observed Properties of Exoplanet Populations to Their Formation
2020The wealth of exoplanetary data as displayed on the mass-semimajor axis and mass-radius distributions reveal a tremendous amount of information constraining our understanding of their formation. We link the variety of outcomes shown in exoplanet populations to the observed ranges of protoplanetary disk properties using the core accretion model of ...
