Advanced simulation methods for the coupled solar interior and atmosphere. This project aims to develop numerical methods for complex magnetohydrodynamic simulations able to handle sharp and dynamically evolving inhomogeneities, spherical geometries, and dramatic variations in density and wave speed across the simulation domain. The project plans to develop these methods within the context of solar wave processes, which are fundamental to the transfer of energy from the sun’s interior to its out ....Advanced simulation methods for the coupled solar interior and atmosphere. This project aims to develop numerical methods for complex magnetohydrodynamic simulations able to handle sharp and dynamically evolving inhomogeneities, spherical geometries, and dramatic variations in density and wave speed across the simulation domain. The project plans to develop these methods within the context of solar wave processes, which are fundamental to the transfer of energy from the sun’s interior to its outer atmosphere, to the acceleration of the solar wind that rushes past the Earth continually, and to solar activity in general. This would provide the best available modelling of how the sun's atmosphere works, with direct implications for how the Earth's space environment is determined by solar storms and eruptions.Read moreRead less
Seismology of solar and stellar magnetic activity. Seismic techniques for looking inside stars using observations of surface oscillations can be confused by the very surface magnetic fields that produce flares and other activity and that we wish to probe. This project will develop a new ray-based code, SunRay, which will be able to explore active regions taking full account of magnetic effects.
A Stress-relax Model for Stellar Flares. This project aims to improve our ability to predict solar and stellar flares by developing a theoretical model for the build-up and release of magnetic stress in stellar atmospheres. Solar flares are the most energetic events in the solar system, and together with associated coronal mass ejections can create hazardous conditions in our local space environment. Stellar flares are thousands of times more energetic and produce dangerous space weather for exo ....A Stress-relax Model for Stellar Flares. This project aims to improve our ability to predict solar and stellar flares by developing a theoretical model for the build-up and release of magnetic stress in stellar atmospheres. Solar flares are the most energetic events in the solar system, and together with associated coronal mass ejections can create hazardous conditions in our local space environment. Stellar flares are thousands of times more energetic and produce dangerous space weather for exoplanets orbiting flare stars. Expected outcomes include insight into the flare mechanism, and new approaches to flare prediction. The major potential benefit is improved solar and stellar space weather forecasting to protect human safety and infrastructure.Read moreRead less
