The aim of this research is to better understand our Sun and its influences on Earth. USQ research in astrophysics comprises several related projects undertaken by staff and students in USQ's Centre for Astronomy and Atmospheric Research. The Sun has an internal dynamo process that generates a magnetic field. When this field emerges at the surface, it produces solar activity such as spots and flares.
Solar activity affects the Earth's magnetic field and upper atmosphere.
It can also pose hazards for orbiting spacecraft. Furthemore, variations in the Sun's activity are also linked to slight but definite changes in solar brightness, with most of the variability occurring at short wavelengths from the ultraviolet to x-rays. There are also suggestions that this variability contributes to terrestrial climate change. Stellar studies can provide a much broader empirical basis for testing theories about the Sun and its magnetism, activity, variability and evolution. Our research at USQ involves participation in an international study of the surface activity and magnetic fields of solar-type stars.
