[Astronomy seminar] Reminder: Astronomy departmental seminar Friday February 9 at 10:30am - Andrius Popovas (RoCS - UiO)

[Astronomy seminar announcements]

Dear all,

This is a reminder of the weekly SU astronomy departmental seminar that 
will take place in about 50 minutes, at 10:30am in room FC61 (AlbaNova 
building, 6th floor) and on zoom 
(https://stockholmuniversity.zoom.us/j/62211269644?pwd=K0J2eVVMa3pTa1JVN2lyRUJPR3Rjdz09). 
As usual, we encourage you to attend in person if possible.

Title: Realistic Simulations of Solar Dynamics
Event: https://indico.fysik.su.se/e/andrius_popovas

Abstract:
Due largely to computational resource limitations, solar research 
evolved as distinct “internal-” and “surface-” related research fields, 
preventing an integrated global view of the Sun's complex plasma 
dynamics. However, the Sun encompasses large-scale hierarchical 
structures, extending from its deep core to its outer atmosphere. 
Magnetic flux, pivotal for many phenomena, such as sunspots and solar 
flares, may be generated through both local and large-scale dynamo 
actions within the solar interior, interacting with motions in the 
convection zone that are ultimately driven by cooling at the very surface.
The current advancements in high performance computing (HPC) 
infrastructure finally allows us to address the burgeoning need for an 
integrated understanding of the solar dynamics from the core to the 
photosphere and beyond.
In this talk I will overview what insights we already got from the large 
scale simulations and present the current state of our work in progress 
– the global compressible MHD simulations covering the entire convection 
zone of the Sun.
