COSPAR Session E23: New perspectives on the solar-stellar connection
Event description:
The corona of our Sun is, to date, the only stellar corona that can be
spatially
resolved and studied at a high level of detail. The solar corona is
therefore
often used as paradigm for the interpretation of the X-ray activity of other
solar-like stars of which we can only observe disk-integrated emission.
Stars, on the other hand, present an enormous range of ages, and other
physical
properties, and thus they provide tools for understanding the long-term
evolution of solar X-ray activity, as well as offering laboratories for
testing
detailed models of solar activity in conditions unavailable to the Sun.
The proposed session aims at providing the solar and stellar communities
with an opportunity for meeting and discussing recent advances in our
understanding
of the physical processes at work in the X-ray emitting outer atmosphere
of the Sun and of stars. The discussion will be particularly focused on
recent results of the Hinode and SDO missions on the solar side, and XMM
and Chandra on the stellar one.
Confirmed Invited Speakers:
Costanza Argiroffi (University of Palermo, Italy)
James Klimchuk (NASA-GSFC, USA)
Isabella Pagano (INAF-Osservatorio Astrofisico di Catania, Italy)
Jurgen Schmitt (Universitaet Hamburg, Germany)

Dear Loops Friends,
If you are interested, the attached paper shows that coronal loops cannot be explained by thermal nonequilibrium. The results appear to rule out the widespread existence of coronal heating that is both highly concentrated low in the corona and steady or quasi-steady (slowly varying or impulsive with a rapid cadence). Comments are welcomed.
Best wishes,
Jim
