Our Dynamical Sun:
a 21st Century View

Although the Sun might appear quite serene to you, our star is in fact, literally, bursting with activity. Frequent violent eruptions of hot matter send seismic waves across the entire Sun’s surface like huge solar tsunamis. Highly-energetic particles stream continuously out from the Sun punctuated by massive blasts of hot plasma that are hurled out from the Sun. So what do these have to do with us? To discover how all this solar activity affects our daily lives, in this talk, we will journey from deep inside the Sun’s nuclear core, through the solar surface, into its atmosphere, on towards Earth and finally out into space. A range of satellites is now observing the Sun in unprecedented detail, giving scientists an ever greater understanding of our local star. I will show some of these amazing current satellite images and movies and explain how scientists use these to create mathematical models of this solar activity.
Prof. Ineke De Moortel FRAS FRSE is a Belgian applied mathematician in Scotland, where she is a professor of applied mathematics at the University of St Andrews, Director of Research in the School of Mathematics and Statistics at St Andrews, and President of the Edinburgh Mathematical Society. Her research concerns the computational and mathematical modelling of solar physics, and particularly of the sun’s corona.
This public lecture series is named after Charlotte Scott, the famous mathematician born in Lincoln, who was also influential in developing mathematical education of women and their participation in mathematical research.
