Deducing Solar Electron Acceleration Parameters with Radio Bursts
If you have a question about this talk, please contact Dr. Jaroslav Dudik.
The Sun is the most efficient particle accelerator in the solar system. Solar flares are the most extreme example of such events, with accelerated particles emitting light across the entire electromagnetic spectrum. Whilst solar flares are impulsive, the magnetic active regions in the solar atmosphere can also cause continuous acceleration over days. Solar accelerated particles affect the Earth through a process known as Space Weather. It is desirable to understand our best local example of astronomical acceleration, however, the inhospitable conditions of the Sun mean we must discern physical parameters by analysis of emitted light. I will show a number of different acceleration parameters that can be estimated through the radio emission from accelerated electrons by using observations and numerical simulations. I will show how linked the radio emission is to X-rays and how this helps us in determining acceleration parameters. I will also show new observations from LOFAR , the next generation European radio interferometer, and highlight how these will improve our understanding of accelerated solar electrons.
