[Astronomy seminar] Reminder: Astronomy departmental seminar Friday April 05 at 10:30am - Simon Ringqvist (Stockholm University)

[Astronomy seminar announcements]

Dear all,

This is a reminder of the weekly SU astronomy departmental seminar that 
will take place in about 86 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.

Speaker: Simon Ringqvist (Stockholm University)
Title: Unveiling the Accretion Process at Planetary Masses
Event: https://indico.fysik.su.se/e/simon_ringqvist

Abstract:
Our understanding of the magnetospheric accretion process in young stars 
has advanced significantly in the last few decades. It is only very 
recently however, that we have been able to also study accreting 
planetary mass companions. I will defend my PhD thesis on this topic, on 
2024-05-27, and today’s talk will therefore provide a scientific 
overview of how we can study these fascinating objects with spectroscopy 
and atmospheric variability studies. Do giant planets accrete matter as 
stars do, by funneling it along magnetic field lines, or are their 
magnetic fields too weak? How long can the accretion phase actually last 
in these objects? Evidence shows that it does not always cease after a 
few Myr, especially not in Delorme 1 (AB)b where it seemingly continued 
for 40 Myr. Concluding the talk will be a brief overview of how upcoming 
ESO pathfinder instruments will drastically improve our ability to 
detect planetary mass accretors.
