Our Dynamical Sun: A 21st Century View
13.15-14.00, Florence Nightingale Day, January 2017
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.
Ineke De Moortel completed a Masters in Mathematics at the KULeuven (Belgium) in 1997. Following a brief stay in St Andrews in the autumn of 1996, as an undergraduate Erasmus exchange student, she returned as a PhD student in September 1997 and received a PhD from the University of St Andrews in 2001. She is currently a professor in Applied Mathematics in St Andrews and an affiliate scientist at the High Altitude Observatory (Boulder, US). She was Co-Chair of the Young Academy of Scotland from 2012-2014.
Her research mostly focuses on the dynamical processes occurring in the Sun's atmosphere, in particular coronal heating and coronal seismology. She was awarded a Philip Leverhulme Prize in 2009 and the Royal Astronomical Society Fowler award in 2010.
