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
