The Quasi-Radial Field-line Tracing (QRaFT): an Adaptive Segmentation of the Open-Flux Solar Corona
Vadim M. Uritsky, Christopher E. Rura, Cooper Downs +3
Optical observations of solar corona provide key information on its magnetic geometry. The large-scale open field of the corona plays an important role in shaping the ambient solar…
Improved Tomographic Reconstruction of 3D Global Coronal Density from STEREO/COR1 Observations
Tongjiang Wang, C. Nick Arge, Shaela I. Jones
Tomography is a powerful technique for recovering the three-dimensional (3D) density structure of the global solar corona. In this work, we present an improved tomography method by…
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…
Prediction and Verification of Parker Solar Probe Solar Wind Sources at 13.3 R
Samuel T. Badman, Pete Riley, Shaela I. Jones +11
Drawing connections between heliospheric spacecraft and solar wind sources is a vital step in understanding the evolution of the solar corona into the solar wind and contextualizin…
Implications of Different Solar Photospheric Flux-Transport Models for Global Coronal and Heliospheric Modeling
Graham Barnes, Marc L. DeRosa, Shaela I. Jones +3
The concept of surface-flux transport (SFT) is commonly used in evolving models of the large-scale solar surface magnetic field. These photospheric models are used to determine the…
New insights into the first two PSP solar encounters enabled by modeling analysis with ADAPT-WSA
Samantha Wallace, Shaela I. Jones, C. Nick Arge +2
Parker Solar Probes's (PSP)'s unique orbital path allows us to observe the solar wind closer to the Sun than ever before. Essential to advancing our knowledge of solar wind and ene…
Solar Polar Flux Redistribution based on Observed Coronal Holes
Samuel J. Schonfeld, Carl J. Henney, Shaela I. Jones +1
We explore the use of observed polar coronal holes (CHs) to constrain the flux distribution within the polar regions of global solar magnetic field maps in the absence of reliable…
Constraining Global Coronal Models with Multiple Independent Observables
Samuel T. Badman, David H. Brooks, Nicolas Poirier +13
Global coronal models seek to produce an accurate physical representation of the Sun's atmosphere which can be used, for example, to drive space weather models. Assessing their acc…
Image-Optimized Coronal Magnetic Field Models
Shaela I. Jones, Joseph M. Davila, Vadim M. Uritsky
We have reported previously on a new method we are developing for using image-based information to improve global coronal magnetic field models. In that work we presented early tes…
Optimizing Global Coronal Magnetic Field Models Using Image-Based Constraints
Shaela I. Jones, Joseph M. Davila, Vadim M. Uritsky
The coronal magnetic field directly or indirectly affects a majority of the phenomena studied in space physics. It provides energy for coronal heating, controls the release of coro…
Coexistence of Self-Organized Criticality and Intermittent Turbulence in the Solar Corona
Vadim M. Uritsky, Maya Paczuski, Joseph M. Davila +1
An extended data set of extreme ultraviolet images of the solar corona provided by the SOHO spacecraft are analyzed using statistical methods common to studies of self-organized cr…
Definitive spectroscopic determination of the transverse interactions responsible for the magnetic quantum tunneling in Mn12-acetate
S. Hill, R. S. Edwards, S. I. Jones +2
We present detailed angle-dependent single crystal electron paramagnetic resonance (EPR) data for field rotations in the hard plane of the S=10 single molecule magnet Mn12-acetate.…
