Modeling the Thermal Low-Frequency Radio Sun with Ray Tracing
Peijin Zhang, Bin Chen, Gregory Fleishman +4
Incoherent radio emission at meter--decimeter wavelengths provides a key diagnostic of the coronal thermal plasma, but at frequencies below \,1\,GHz coronal refraction can su…
Tracking Magnetic Topological Change in a Time-Dependent Coronal Model
Emily I. Mason, Cooper Downs, Roberto Lionello +2
We apply the slip-back mapping method of Titov et al. 2009 and Lionello et al. 2020 to a thermodynamic MHD simulation to track topological changes in the magnetic field at a range…
Understanding the complex morphology of a CME II: how pre-eruptive conditions shape CME evolution
Abril Sahade, Cecilia Mac Cormack, Angelos Vourlidas +4
The morphology and heliospheric impact of coronal mass ejections (CMEs) are strongly shaped by their preeruptive magnetic configuration and surrounding coronal environment, yet the…
Magnetic Connectivity in the Time-Dependent Corona and Heliosphere
Roberto Lionello, Cooper Downs, Emily I. Mason +3
Magnetic flux fills the heliosphere, expands outward from the solar corona, and is fundamentally related to the structure and dynamics of the solar corona and solar wind. Open magn…
Quantitative Image-Based Validation Framework for Assessing Global Coronal Magnetic Field Models
Christopher E. Rura, Vadim M. Uritsky, Shaela I. Jones +3
Coronagraph observations provide key information about the orientation of the Sun's magnetic field. Previous studies used various algorithms to segment quasi-radial features in cor…
Quantifying how Surface Complexity Influences Properties of the Solar Corona and Solar Wind
Caroline L. Evans, Cooper Downs, Donald Schmit
The Sun's magnetic field is a key driver in coronal heating and consequently solar wind acceleration. Remote measurement of the photosphere provides the magnetic surface boundary c…
