[Astronomy seminar] Astronomy Seminar 3/6

[Astronomy seminar announcements]

On Friday 3/6  at 10:30 we will have our next Astronomy seminar. The speaker is Jayant Joshi (Indian Institute of Astrophysics).
The seminar will be on zoom only.
Please join in time.



Signatures of ubiquitous magnetic reconnection in the lower
solar atmosphere

Magnetic reconnection is a fundamental mechanism for many
dynamic and transient events in the solar atmosphere, such as flares,
coronal mass ejections (CMEs), jets, Ellerman bombs, ultra-violet (UV)
bursts, and x-ray bright points. Ellerman Bomb is a magnetic
reconnection phenomenon in the solar lower atmosphere, manifesting as
intense brightenings in the wings of the hydrogen Balmer lines.
Recently, it has been found that Ellerman-like brightenings also exist
in the quiet sun and are known as quiet Sun Ellerman bombs. These are a
signature of the fundamental process of magnetic reconnection at the
smallest observable scale in the lower solar atmosphere. The speaker
will present high spatio-temporal observations in the hydrogen Blamer-β
line which reveal the ubiquitous presence of magnetic reconnection in
the lower solar atmosphere. The ubiquitous small-scale reconnection
events would be the key to understanding the dissipation of quiet-Sun
magnetic energy and the reconfiguration of magnetic fields.
