Recent stellar and asteroseismic observations from missions such as NASA's Kepler satellite have revealed the presence of powerful flares on many distant stars. Our local equivalent, solar flares - the largest explosions in the solar system, take place in the outer layers of the solar atmosphere. They release enormous amounts of energy equivalent to millions of hydrogen bombs going off in a matter of minutes. While most of the energy is released into outer space, a portion of it travels down to the surface, sometimes violently shaking the Sun and generating acoustic waves that propagate into the interior before coming back to the surface. Such events are called sunquakes and can sometimes be seen on the solar surface as tsunami-like wavefronts accelerating outward from the point of surface impact. The enhanced acoustic emission in response to solar flares was predicted in the 70s but first observational evidence was obtained only recently with many fundamental questions about the phenomena remaining unanswered to this day
Many stars, like the Sun, oscillate and pulsate revealing their internal properties via their frequency spectra. During its lifetime the Kepler mission has accumulated data of unprecedented quality and quantity for the study of stars, in particular through its use of asteroseismology, the study of stellar pulsations to infer internal structure and properties of the stars.
In this project we will use our growing knowledge of the solar sunquake phenomena to develop new methods and models for detecting and analysing such events on the Sun that will then be extended to stellar observations. We will develop and test new helioseismic techniques of sunquake detection and analysis from âSun as a starâ measurements. We will then compare the results with the current state of the art methods leading to new insights into sunquake generation questions. We will then apply the new methods to analyse the data from stellar observations such as those from Kepler mission. The project will also provide insight into one of the outstanding questions of flare seismology research: why sunquakes are relatively rare, with many of the solar flares showing no detectable acoustic emission?
