Characterization of extrasolar planets using high-precision polarimetry. Close to a thousand exoplanets have been found since the discovery of a planet around a Sun-like star, 51 Peg in 1995. With the Kepler space telescope, we are now capable of finding Earth-size worlds around other stars. But how do we know if these Earth-like planets have all the right ingredients for life like ours to flourish?

Close to a thousand exoplanets have been found since the discovery of a planet around a Sun-like star, 51 Peg in 1995. With the Kepler space telescope, we are now capable of finding Earth-size worlds around other stars. But how do we know if these Earth-like planets have all the right ingredients for life like ours to flourish? Polarimetry is a powerful method of exoplanet characterisation that could one day answer such questions and can be applied, right now, to the giant planets. An innovative, portable polarimeter will be developed, that will be used to understand the atmospheric composition of exoplanets. Polarimetry is a promising method, which in the future may be the first method that can detect liquid water on extrasolar planets.Read moreRead less
Extrasolar terrestrial planets - How Earth-like can they be? This research will answer the key question for current exoplanetary studies and searches - 'Are there other Earths in the Universe?' - by studying not only the processes via which terrestrial planets form, but also by modelling the elemental composition of extrasolar terrestrial planets so that we can understand just how 'Earth-like' they can be.
