Dear all,
please find below the second announcement of the 11th Coronal Loops
Workshop.
Kind regards,

11th Coronal Loops Workshop - Second announcement
The 11th Coronal Loops Workshop will be held from 25-28 June 2024 in the
city of San Cristobal de La Laguna (Tenerife, Spain). The Coronal Loops
Workshops are a series of highly focused biennial meetings, organized
since 2002. They deal with the observation and modeling of magnetically
confined solar plasma.
In addition to discussions of recent progress in community driven topics
that will be based on the abstracts submitted, this meeting will include
sessions on three specific themes: coronal cooling, reconciling 1D vs 3D
models, and high resolution observations.
The confirmed invited speakers are: Lakshmi Pradeep Chitta (Max Planck
Institute for Solar System Research), Petra Kohutova (Rosseland Center
for Solar Physics), Paolo Pagano (Università di Palermo), Elena Petrova
(KU Leuven), Jeffrey Reep (University of Hawaii), and Seray Sahin
(University of Northumbria).
The abstract submission (for talks and posters) and pre-registration
will open on the 1st of March. We encourage graduate students and
early-career postdocs to participate and present their research work.
While abstracts are not required for participation, preference will be
given to those who submit abstracts, in order to limit the number of
participants to 75.
The registration fee (350 EUR, TBC) includes the workshop, a welcome
reception, coffee breaks, lunches from Tuesday to Thursday, and the
conference dinner on Thursday.
We are pleased to announce that a National Science Foundation (NSF)
Conference Proposal was funded to support the travel costs of students
and early career post-docs from different institutions across the US.
Those with financial need and from under-represented groups in solar
physics will be prioritized. Additional information on these NSF travel
grants together with the eligibility criteria and requirements for
applicants can be found on the workshop website.
The LOC aims to offer a limited number of registration fee waivers, with
preference for early career researchers.
To apply for support or request further information, please send your
request in an e-mail to the contact address below, with Subject
including “[Fee waiver request]” or "[NSF support]", before 15 April 2024.
Important dates
1 March 2024: pre-registration and abstract submission open
15 April 2024: abstract submission closes
1 May 2024: notification of acceptance of contributions and support
1 June 2024: deadline for payment of the registration fee

Hi all,
Just wanted to tell people about the following paper that has been accepted by ApJ and is on arXiv
Modeling of Condensations in Coronal Loops Produced by Impulsive Heating
T.A. Kucera , J. Klimchuk (671), M. Luna (U. Illes Balears)
https://arxiv.org/abs/2402.06799
We presents 1D hydrodynamic model results looking into how coronal loops produce cool condensations (i.e., coronal rain) in response to localized impulsive heating events that are randomized in time, intensity and location. We find that in order to produce cool condensations with randomized heating it is even more important than with non-randomized heating that the heating be near the loop foot points and at high average frequencies, and that the condensations tend to fall out of the loop more quickly. That said, condensations can sometimes occur in cases where the average values of frequency or height in the loop are beyond the critical limits above which condensations do not occur for corresponding steady, non-randomized values of those parameters.
Cheers,
Terry

Dear friends,
You might be interested in the attached paper by Vadim Uritsky and me concerning the shapes of loop cross sections. Vadim compared intensity traces across loops in real images from Hi-C and synthetic images generated with a variety of assumed cross-sectional shapes. By applying several statistical measures, we concluded that the Hi-C loops tend to be more "tube like" (roughly circular cross sections) than ribbon like or veil like. This is consistent with the findings of two other Hi-C observational papers (Klimchuk & DeForest, 2020, ApJ, 900, 167; Williams, Walsh, & Morgan, 2021, ApJ, 919, 47) and a recent paper by Sudip Mandal and colleagues using EUI/SolO data, also attached.
Cheers,
Jim
