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

Veloce Verde+Azzuro - Tripling the Power of Australia's Planet Foundry. This project aims to better understand humanity’s place in the Universe, including questions such as whether we are alone or if our home in the Solar System is unique or common. This project will enable new observations using a revolutionary Australian facility, Veloce Verde+Azzuro. Moving beyond discovering habitable planets around dim red stars, it will enable science on the properties and system architectures of planets o ....Veloce Verde+Azzuro - Tripling the Power of Australia's Planet Foundry. This project aims to better understand humanity’s place in the Universe, including questions such as whether we are alone or if our home in the Solar System is unique or common. This project will enable new observations using a revolutionary Australian facility, Veloce Verde+Azzuro. Moving beyond discovering habitable planets around dim red stars, it will enable science on the properties and system architectures of planets orbiting stars like the Sun. It will deliver a ten-fold increase in collecting power for Sun-like stars, providing understanding of how exoplanetary systems, and our Solar System, were formed.Read moreRead less

VeloceCal: hyper-calibrating Australia's planet foundry:
VeloceCal aims to deliver a hyper-calibration capability to Australia's premier high-resolution optical spectrograph, such that instrumental drifts will make an insignificant contribution to the system's Doppler velocity measurement capabilities. This would transform Australian capabilities for the measurement of masses (and so densities) for the lowest mass planets which will be emerging from NASA's next-generation Transiting Exoplanet Survey Satellite (TESS) from 2017 onwards. VeloceCal would play a pivotal role in determining whether the smallest planets found by TESS are terrestrial (like the Earth) or icy (like Neptune), and in unambiguously discovering terrestrial planets orbiting low-mass stars in habitable orbits.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.
A New Era for Australian Exoplanetary Science. There are few areas of learning that engage the public in cutting-edge science and technology more than astronomy – and few areas of astronomy that engage and fascinate as thoroughly as the study of planets and astrobiology. This research program will not only discover new rocky and gas giant planets orbiting other stars, but tell us about how those planets formed – allowing us to answer the key question for current exoplanetary research – “Are ther ....A New Era for Australian Exoplanetary Science.
