The pathway to planets: formation of protoplanetary discs. This project aims to expand our knowledge of how planetary systems are born. Observations are bringing new insight into the structure of discs of dusty gas orbiting young stars, but not in sufficient detail to understand how planets form within them. This project aims to link the structure of discs to the well-characterised interstellar cloud cores that collapse to form star-disc systems. The project aspires to use innovative techniques ....The pathway to planets: formation of protoplanetary discs. This project aims to expand our knowledge of how planetary systems are born. Observations are bringing new insight into the structure of discs of dusty gas orbiting young stars, but not in sufficient detail to understand how planets form within them. This project aims to link the structure of discs to the well-characterised interstellar cloud cores that collapse to form star-disc systems. The project aspires to use innovative techniques to enable the rapid collapse calculations needed to map core properties to disc structure. Expected outcomes include knowledge of the disc structures critical to interpreting observations of forming planetary systems. The benefit will be guidance to the theory needed to explain the incredible variety of planetary systems we see today.Read moreRead less

DREAMS is a revolutionary wide-field infrared surveyor designed to allow astronomers to unlock new science and foster international collaborations focused on important but elusive, infrared transient cosmic phenomena. Continually scanning the southern sky, DREAMS will provide “real time” data that will transform the depth and quality of astronomical observation. Combining off-the-shelf parts with scientific expertise from around the world, this telescope will help answer questions that are both practical and profound. DREAMS is an important component of a longer-term international strategy that will reinforce Australia’s global leadership in the realm of Infrared Transient Astronomy.Read moreRead less
Supernovae as the origin of antimatter in our galaxy. This project aims to uncover the origin of the bulk of the antimatter in our Milky Way Galaxy. Astrophysicists have known for forty years that our Galaxy glows with gamma-rays emitted by the annihilation of huge numbers of positrons, the antimatter partners to electrons. Certain supernovae are the likely source of these positrons. To fully investigate this idea and its ramifications, this project will perform three-dimensional supercomputer s ....Supernovae as the origin of antimatter in our galaxy. This project aims to uncover the origin of the bulk of the antimatter in our Milky Way Galaxy. Astrophysicists have known for forty years that our Galaxy glows with gamma-rays emitted by the annihilation of huge numbers of positrons, the antimatter partners to electrons. Certain supernovae are the likely source of these positrons. To fully investigate this idea and its ramifications, this project will perform three-dimensional supercomputer simulations of thermonuclear supernova explosions. This project aspires to resolve a long-standing mystery in astrophysics and provide an exemplar for best usage of Australian investment in astronomy and supercomputing infrastructure.Read moreRead less
Precision pair spectroscopy of the Hoyle state. This project aims to develop a novel new spectrometer to observe and characterise electron-positron pairs of high energy nuclear transitions with unprecedented precision. Building on unique Australian expertise and equipment, the outcomes will include new applications of electron spectroscopy to nuclear structure studies, and a better understanding of element synthesis in the universe, including the formation of 12C in the universe.
Understanding other worlds: the composition, structure and evolution of exoplanet atmospheres. This project will advance our understanding of the rapidly growing number of planets being found around other stars. The project will develop new techniques to determine what their atmospheres are made of, how the planets form and evolve, and whether they have the potential to host life.
Wobbling stars reveal their hidden companions. This project aims to measure the wobble in the position of distant stars that is caused by massive objects, using telescopes in space. This project expects to generate new knowledge on how binary stars, exoplanets, and stellar mass black holes are formed. Expected outcomes of this project include tight constraints on binary star models, new discoveries of neutron stars and black holes that are a few times more massive than the Sun, and samples of st ....Wobbling stars reveal their hidden companions.

This project expects to generate new knowledge on how binary stars, exoplanets, and stellar mass black holes are formed. Expected outcomes of this project include tight constraints on binary star models, new discoveries of neutron stars and black holes that are a few times more massive than the Sun, and samples of stars that do, and do not, host exoplanets. This should provide significant benefits including a catalogue of companion properties for billions of sources, new understanding of how stars die, as well as the first control sample of stars without planets to help understand how and why planets form.Read moreRead less

This project aims to develop thermal infrared technologies for the Very large telescope interferometer Infrared Kernel-NullinG instrument (VIKiNG), making it the most capable direct exoplanet detection instrument on any existing, or under construction, facility. Australia is currently world leading in innovative photonics technologies, and these are currently the limiting factor in producing a manufacturable design for VIKiNG. This project provides a clear pathway for laboratory development of high-efficiency, active mid-infrared photonic circuits in the thermal infrared. Beyond benefits to astronomy, these circuits are the first step in developing remote molecule detectors for environmental monitoring and security.Read moreRead less
Adolescent stars and planets in our neighbourhood from Gaia and FunnelWeb. This project aims to understand how infant stars in their stellar nurseries reach adulthood in the Galactic disk, and link stellar birth to the presence and evolution of adolescent planetary systems. The billion dollar Gaia satellite will change the study of stellar adolescence, with data beginning to flow with an initial public release this year.

This project aims to understand how infant stars in their stellar nurseries reach adulthood in the Galactic disk, and link stellar birth to the presence and evolution of adolescent planetary systems. The billion dollar Gaia satellite will change the study of stellar adolescence, with data beginning to flow with an initial public release this year. FunnelWeb – the largest star survey of its kind, covering the entire Southern sky – will augment this data. This project will combine these datasets, identifying the birthplace of the majority of nearby adolescent stars in the Southern sky and helping to discover and characterise their planetary systems. The results relating to the origin and Galactic context of our solar system are of broad public interest.Read moreRead less
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
