[Astronomy seminar] Reminder: Astronomy departmental seminar Friday September 22nd at 10:30am - Hendrik C. Spruit (Max Planck Institute for Astrophysics)

[Astronomy seminar announcements]

Dear all,

This is a reminder of the weekly SU astronomy departmental seminar that 
will take place in about 45 minutes, *at 10:30am in room FC61* (AlbaNova 
building, 6th floor) *and on zoom* 
(https://stockholmuniversity.zoom.us/s/61002076352). As usual, we 
encourage you to attend in person if possible.

Speaker: Prof. Hendrik C. Spruit (Max Planck Institute for Astrophysics)
Title: Historical overview (and misconceptions) of convection in 
solar/stellar atmospheres
Event: https://indico.fysik.su.se/e/hendrik-spruit

Abstract:
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.

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