Our research has shown what sunsets look like on extrasolar planets.
Research into exoplanets is teaching us more about our own planet, its history, and its future.
Modelling climates on extrasolar planets
Our first tests demonstrate the superiority of the Unified Model and significant improvement that can be expected using this tool for the study of exoplanets.
The underlying physics determining the behaviour of an exoplanet atmosphere is similar to that which determines the behaviour of the Earth's atmosphere, so the Unified Model can be applied to planets other that Earth. However some exoplanets are very different to anything in our own Solar system and present some distinct challenges to the model.
High temperature planets
We have gained new insight into the formation and physical properties of extrasolar planets through our collaborative work on high temperature planets, carried out using the NASA Hubble Space Telescope.
We achieved greater understanding of heat redistribution work on modelling climates on extrasolar planets, in partnership with the Met Office. This work, led by Extrasolar Planets theme leader Prof Isabelle Baraffe, saw the Met Office's climate model adapted to study the atmospheric properties of planets orbiting other stars.
Planets orbiting other stars
The first ever image of multiple planets orbiting a star other than our own was captured by an award winning team including Exeter's Dr Jenny Patience. The team scooped the 2009 Newcomb Cleveland Prize of the American Association for the Advancement of Science (AAAS) which recognises an outstanding paper published in the leading academic journal, Science.
Sunsets on other planets
The ExoClimes website, which is maintained by astrophysicists at the University of Exeter and the University of Oxford, has been used to share results with professional and amateur astronomers. This has included work showing how sunsets look on other planets. Writing on the website Prof Frédéric Pont said the sunset on the planet HD 209 (Osiris) 'looks truly alien' because the star is white outside the atmosphere then acquires a bluish tinge as it sets.
