Derivation and Application of a Scaling Between Hinode/SP and SDO/HMI Vector Magnetic Fields to Improve Magnetic Field Extrapolations
C. Beck, A. Prasad, Q. Hu +3
Full-disk measurements of the solar magnetic field by the Helioseismic and Magnetic Imager (HMI) are often used for magnetic field extrapolations, but its limited spatial and spect…
Heating of the solar chromosphere in a sunspot light bridge by electric currents
Rohan E. Louis, Avijeet Prasad, Christian Beck +2
Context: Resistive Ohmic dissipation has been suggested as a mechanism for heating the solar chromosphere, but few studies have established this association. Aim: We aim to determi…
Effects of Cowling Resistivity in the Weakly-Ionized Chromosphere
Mehmet Sarp Yalim, Avijeet Prasad, Nikolai Pogorelov +2
The physics of the solar chromosphere is complex from both theoretical and modeling perspectives. The plasma temperature from the photosphere to corona increases from ~5,000 K to ~…
A Modified Spheromak Model Suitable for Coronal Mass Ejection Simulations
Talwinder Singh, Mehmet S. Yalim, Nikolai V. Pogorelov +1
Coronal Mass Ejections (CMEs) are one of the primary drivers of extreme space weather. They are large eruptions of mass and magnetic field from the solar corona and can travel the…
Simulating Solar Coronal Mass Ejections constrained by Observations of their Speed and Poloidal flux
Talwinder Singh, Mehmet Sarp Yalim, Nikolai Pogorelov +1
We demonstrate how the parameters of a Gibson-Low flux-rope-based coronal mass ejection (CME) can be constrained using remote observations. Our Multi Scale Fluid-Kinetic Simulation…
A Data-Driven MHD Model of the Global Solar Corona within Multi-Scale Fluid-Kinetic Simulation Suite (MS-FLUKSS)
Mehmet Sarp Yalim, Nikolai Pogorelov, Yang Liu
We have developed a data-driven magnetohydrodynamic (MHD) model of the global solar corona which uses characteristically-consistent boundary conditions (BCs) at the inner boundary.…
