Cloud formation in brown dwarfs and extrasolar planets
30 November 2017, FMF Symposium 2017, Groningen
Cloud formation is a long-standing challenge that recently received new attention with the discovery of brown dwarfs and extrasolar planets. Clouds are part of our everyday-life on Earth, most of the solar system planets are covered with clouds, and clouds do determine (and limit) our knowledge about exoplanet’s habitability. Clouds are linked to lightning which is discussed as trigger for life on Earth and maybe elsewhere. Modelling the formation of clouds is seen as one of the biggest challenges in modern astronomy, and clouds introduce the largest uncertainty into terrestrial climate predictions. So, have we reached our limits?
