Solar Wind Dependence on Source Distance from the Open-Closed Boundary
Chloe P. Wilkins, David I. Pontin, Anthony R. Yeates +2
The origin and variability of the slow solar wind remains an open question in solar physics, but is thought to be closely linked to dynamics at the Sun's open-closed magnetic flux…
A Non-Spherical Model for the Solar Coronal Magnetic Field
Ziqi Wu, Jiansen He, Chuanpeng Hou +7
The coronal magnetic field plays a fundamental role in governing coronal activities, driving space-weather events, and shaping the heliosphere. Due to a lack of direct observations…
A magnetic avalanche as the central engine powering a solar flare
L. P. Chitta, D. I. Pontin, E. R. Priest +17
Solar flares are the most powerful, magnetically driven, explosions in the heliosphere. The nature of magnetic energy release in the solar corona that heats the plasma and accelera…
Generation of Surface Sausage Oscillations of a Current Sheet and Propagating Magnetoacoustic Waves by Impulsive Reconnection
Sripan Mondal, A. K. Srivastava, David I. Pontin +1
Magnetic reconnection and Magnetohydrodynamic (MHD) waves may well be both playing a role in coronal heating. In this paper, we simulate reconnection in the corona as a response to…
The Sun's open-closed flux boundary and the origin of the slow solar wind
Chloe P. Wilkins, David I. Pontin, Anthony R. Yeates +3
The Sun's open-closed flux boundary (OCB) separates closed and open magnetic field lines, and is the site for interchange magnetic reconnection processes thought to be linked to th…
Localized Heating and Dynamics of the Solar Corona due to a Symbiosis of Waves and Reconnection
A. K. Srivastava, Sripan Mondal, Eric R. Priest +6
The Sun's outer atmosphere, the corona, is maintained at mega-Kelvin temperatures and fills the heliosphere with a supersonic outflowing wind. The dissipation of magnetic waves and…
