Planet formation enters the observational era – an EAS 2020 SYMPOSIUM

Aims and scope Traditionally, planet formation was mostly a theoretical field, with rather loose observational constraints coming from proto-planetary disc observations and the Solar System. The field is now rapidly transforming thanks to ALMA and extreme adaptive optic systems, which recently made it possible to detect for the first time forming planets in proto-planetary discs and study in detail the structure and chemical composition of the planet building-blocks. Some of these ingredients, such as planetesimals, persist across the main sequence as debris discs, allowing us to study the architectures of (proto)planetary systems across both space and time as they evolve. ...
