Exoplanet Characterisation and Demographics in 2022 and Beyond
Exoplanets2
In the last few decades, the field of exoplanet research has blossomed into a tour de force within the wider field of Astronomy. With the advent of missions such as Kepler, K2, WASP and TESS, we have discovered thousands of extra-solar worlds. But just discovering them is not enough - we want to learn more about them: their sizes, masses, densities and internal compositions; their resonances, obliquities, transit timing variations and orbital configurations. So far, we have seen a breathtaking diversity of systems beyond our wildest predictions, including hot Jupiters with orbital periods of mere days, stripped cores in the Neptunian desert, multi-planet systems that rival our own Solar System in planet count, and young planets that have been directly imaged. We have been able to begin to make statistical studies on the exoplanet population too, discovering the radius valley and the Neptunian desert, finding correlation between planet occurrence and the properties of stars - and considering the implications on planet formation and evolutions pathways that these might have. This session aims to highlight the breadth of exoplanet follow-up research, current and future, stemming from a variety of facilities (both space and ground-based), data analysis techniques and modelling, as well as showcasing the exoplanet demographics we can begin to deduce from this and dedicated follow-up programs.
