Invitation to the Next SP2RC – Sheffield Research Group Seminar

Dear Colleague,

Based on the recent UKSP survey feedback, the majority of our community has expressed an interest in joining and is keen to share their online seminars.

With this in mind, we wish to draw your attention to the upcoming seminar talk titled “Why do spicules spin in the images taken at the solar limb” by Piyali Chatterjee, Associate Professor at the Indian Institute of Astrophysics.

This seminar is on Friday, 13th October at 13:00 (UK time) and is hosted by the SP2RC – Sheffield research group. For more details, see below. The SP2RC group welcomes everyone who wants to join.

If you are interested in sharing your forthcoming seminar with the broader community, we kindly ask that you contact Karen Meyer (KMeyer001@dundee.ac.uk) and Rahul Sharma (rahul4.sharma@northumbria.ac.uk) directly for more specifics.

Warm regards,

The UKSP Council

Abstract:
Bunches of swaying spicules in the solar chromosphere exhibit a variety of complex dynamics that are clearly observed in the images of coronal hole regions. By calculating the line-of-sight integrated emission from three-dimensional radiative magnetohydrodynamic simulations, we obtain multiple episodes of rotation amongst clusters of spicules also reported in the sequence of high cadence observations on the solar limb. This perception of rotation, according to our findings, is associated with hot swirling plasma columns that we label as coronal swirling conduits (CoSCo). Some tall CoSCos seen in our simulations can potentially form by feeding on spicules and channeling this energy to the upper reaches of the solar atmosphere, even while the corresponding spicules fall back sun-ward.
