Stellar chemical signatures of planet formation. Through demanding observations with the largest telescopes and extremely accurate analyses, the project will search for the characteristic fingerprints of planet formation imprinted in the chemical compositions of the sun and stars that we have discovered. The work will shed light on the origin of the solar system and identify stars harbouring planets.
Understanding the sources of the slow solar wind. This project aims to reveal the origins of the slow solar wind, a continuous stream of plasma emanating from the Sun that fills the solar system and impacts the Earth. This project expects to enhance our understanding of how this solar wind is accelerated and structured using a suite of state-of-the-art computational simulations. In doing this, the project expects to provide critical physical understanding to allow interpretation of data from NA ....Understanding the sources of the slow solar wind. This project aims to reveal the origins of the slow solar wind, a continuous stream of plasma emanating from the Sun that fills the solar system and impacts the Earth. This project expects to enhance our understanding of how this solar wind is accelerated and structured using a suite of state-of-the-art computational simulations. In doing this, the project expects to provide critical physical understanding to allow interpretation of data from NASA and ESA's flagship space missions Parker Solar Probe and Solar Orbiter. Benefits should include enhanced physical understanding that will contribute to the international effort to develop reliable space-weather forecasting systems, critical for space exploration and space-based technology.Read moreRead less
Next generation space weather forecasts. Next generation space weather forecasts. This project aims to improve Australia's space weather prediction capabilities by developing space weather forecasts that use ground- and space-based GPS data. The Earth's ionosphere is temporally and spatially variable and the small number of observations limits understanding of its dynamics and effects on radio waves. Using ground- and space-based GPS to remotely sound the ionosphere increases this coverage and c ....Next generation space weather forecasts. Next generation space weather forecasts. This project aims to improve Australia's space weather prediction capabilities by developing space weather forecasts that use ground- and space-based GPS data. The Earth's ionosphere is temporally and spatially variable and the small number of observations limits understanding of its dynamics and effects on radio waves. Using ground- and space-based GPS to remotely sound the ionosphere increases this coverage and can be used to develop space weather forecasts tailored to industries that heavily rely on GPS and satellite communications. An expected direct outcome of this research is modernised space weather forecasts, with economic benefits for several industries.Read moreRead less
Prediction of coronal mass ejections and their radio emissions.

Integrated Observation, Theory, and Simulation of Type II Solar Radio Bursts. Type II solar radio bursts are associated with solar flares, coronal mass ejections (CMEs), and space weather events at Earth.

Integrated data-tested theory and modelling of type three solar radio emissions. Type three solar radio emissions, the Sun's most powerful and common, are the archetypal collective radio phenomenon in space physics and astrophysics. The project will integrate new theoretical work and simulations into a first integrated data-tested theory that can explain type three bursts, resolve long standing issues, and constrain solar physics.
Prediction of solar activity and space weather by automated analyses of solar radio and magnetic field observations and simulations. This project will build world-recognised capabilities to forecast space weather events at Earth in time to take protective measures. It involves around the clock automated identification and analysis of specific solar radio bursts, forecasting solar activity that results in transients moving Earth-ward, and simulations to predict when these will reach Earth.

Geomagnetic induced currents in the Australian electricity supply network. This project will develop measures to protect the Australian electricity supply network from adverse effects of enhanced solar activity.

Electrodynamics of magnetic explosions in astrophysics. The project aims to develop a new model for solar flares and pulsars that more realistically describes these phenomena. Solar flares and pulsars involve strong magnetic fields changing rapidly as a function of time, implying enormous inductive potentials. The project aims to show how the inductive field and the plasma response to it can be included in an electrodynamic theory. It plans to apply this theory to solar flares, and show how it c ....Electrodynamics of magnetic explosions in astrophysics. The project aims to develop a new model for solar flares and pulsars that more realistically describes these phenomena. Solar flares and pulsars involve strong magnetic fields changing rapidly as a function of time, implying enormous inductive potentials. The project aims to show how the inductive field and the plasma response to it can be included in an electrodynamic theory. It plans to apply this theory to solar flares, and show how it can resolve the long-standing ‘number problem’. It also plans to apply the model to pulsars, and show how the long-standing dichotomy between the vacuum-dipole and rotating-magnetosphere models can be resolved by synthesising them. The project intends to combine these ideas into a new model for the most extreme examples of magnetic explosions: superflares and giant bursts on magnetars.Read moreRead less
