[Loops] Two new papers

[Stephen Bradshaw]

Hello everyone,

 

Here are two new papers by Peter Cargill and me that may be of interest to
you.

 

The first "The influence of numerical resolution on coronal density in
hydrodynamic models of impulsive heating" takes what we believe to be a
long-overdue look at the issues surrounding the question of grid resolution
in numerical models and some of the physical implications of under-resolving
particular regions of the solar atmosphere. The paper has already been
published by ApJ and can be obtained here:
http://iopscience.iop.org/0004-637X/770/1/12/pdf/0004-637X_770_1_12.pdf

 

The second "The Cooling of Coronal Plasmas. iv: Catastrophic Cooling of
Loops" is a continuation of our series on the relevant cooling processes in
the solar atmosphere. Here we provide a physical explanation of the onset of
catastrophic cooling, which may provide an explanation for the relatively
weak active region emission detected in wavelength channels sensitive to
lower temperature lines. The manuscript has been accepted for publication by
ApJ and is available on astro-ph:
http://arxiv.org/ftp/arxiv/papers/1305/1305.5484.pdf

 

Hope to see many of you in Montana!

 

Best,

 

Steve
