Presentation
Solar prominences are large clouds of cool, dense plasma that hover in the corona, the outer part of the solar atmosphere. They can remain stable for days or even weeks, but sometimes they suddenly erupt, launching massive clouds of plasma into space. Such eruptions are one of the main drivers of space weather, which can disturb satellites, power grids, and communication systems on Earth. Understanding the formation, dynamics, and eruptions of prominences is therefore essential both for fundamental solar physics and for predicting their impact on the near-Earth environment.
In this talk, Valeriia will present recent advances in numerical modeling of prominences using state-of-the-art magnetohydrodynamic (MHD) simulations. She will show how such models help us investigate the physical mechanisms behind their formation, oscillations, and eruptions. By synthesizing observables from the simulations, we can also make direct comparisons with space-based and ground-based observations, providing the basis for the interpretation of the observations.
Speaker
Valeriia Liakh is a Postdoctoral Fellow at the Rosseland Centre for Solar Physics, where she uses different methods to study prominence "tornadoes"—highly dynamic structures whose role as potential CME precursors remains an open question in solar physics. She received her PhD in Astrophysics from the Instituto de Astrofísica de Canarias (IAC) in 2021.
Program
11:30 – Doors open and lunch is served
12:00 – "Modeling Solar Prominences: A Space Weather Perspective" by Valeriia Liakh (Postdoctoral Fellow, Rosseland Centre for Solar Physics)
This event is open for all students, PhD candidates, postdocs, and everyone else who is interested in the topic. No registration needed.
About the seminar series
Once a month, dScience will invite you to join us for lunch and professional talks at the Science Library. In addition to these, we will serve lunch in our lounge in Kristine Bonnevies house every Thursday. Due to limited space (40 people), this will be first come, first served. See how to find us here.
Our lounge can also be booked by PhDs and Postdocs on a regular basis, whether it is for a meeting or just to hang out – we have fresh coffee all day long!
