<div>Dear all,<br>
<br>
The next SU astronomy departmental seminar will take place on Friday September 22nd at 10:30am in room FC61 (AlbaNova building, 6th floor) and on zoom (https://stockholmuniversity.zoom.us/s/61002076352).<br>

Speaker: Prof. Hendrik C. Spruit (Max Planck Institute for Astrophysics)<br>
Title: Historical overview (and misconceptions) of convection in solar/stellar atmospheres<br>
Event: https://indico.fysik.su.se/e/hendrik-spruit<br>
<br>
Abstract:<br>
Controversial discussions about the nature of the Sun's granulation date back almost a century. How can a flow with a Reynolds number of 10^12 look more like a bowl of soup than ferocious turbulence? After a historical overview I discuss how the answer is closely
related to a misconception about the forces that drive the granulation as they are observed in ever improving observations and realistic numerical simulations. A closer look at this problem also explains the so-called 'convection conundrum': the discrepancy
between results from helioseismic measurements of subsurface flows' on the one hand and 'whole convection zone' simulations on the other.<br>

We look forward to seeing many of you there. Thanks!<br>
