Heating and cooling at a coronal magnetic null
P. J. Cargill, A. W. Hood, D. Johnson
Conductive cooling of the solar corona at a magnetic null is examined. An initial equilibrium is set up, balancing thermal conduction and a constant, spatially uniform coronal heat…
Static and dynamic solar coronal loops with cross-sectional area variations
P. J. Cargill, S. J. Bradshaw, J. A. Klimchuk +1
The Enthalpy Based Thermal Evolution of Loops (EBTEL) approximate model for static and dynamic coronal loops is developed to include the effect of a loop cross-sectional area which…
High resolution soft X-ray spectroscopy and the quest for the hot (5-10 MK) plasma in solar active regions
G. Del Zanna, V. Andretta, P. J. Cargill +5
We discuss the diagnostics available to study the 5-10 MK plasma in the solar corona, which is key to understanding the heating in the cores of solar active regions. We present sev…
Modelling the solar transition region using an adaptive conduction method
C. D. Johnston, P. J. Cargill, A. W. Hood +3
Modelling the solar Transition Region with the use of an Adaptive Conduction (TRAC) method permits fast and accurate numerical solutions of the field-aligned hydrodynamic equations…
The effects of numerical resolution, heating timescales and background heating on thermal non-equilibrium in coronal loops
C. D. Johnston, P. J. Cargill, P. Antolin +3
Thermal non-equilibrium (TNE) is believed to be a potentially important process in understanding some properties of the magnetically closed solar corona. Through one-dimensional hy…
Comparison of Methods for modelling Coronal Magnetic Fields
E. E. Goldstraw, A. W. Hood, P. K. Browning +1
Four different approximate approaches used to model the stressing of coronal magnetic fields due to an imposed photospheric motion are compared with each other and the results from…
