Proposed Resolution to the Solar Open Magnetic Flux Problem

C. Nick Arge, Andrew Leisner, Samantha Wallace +1

The solar magnetic fields emerging from the photosphere into the chromosphere and corona are comprised of a combination of "closed" and "open" fields. The closed magnetic field lin…

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…

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…

On the Relationship between Magnetic Expansion Factor and Observed Speed of the Solar Wind from Coronal Pseudostreamers

Samantha Wallace, Charles N. Arge, Nicholeen M. Viall +1

For the past 30+ years, the magnetic expansion factor () has been used in empirical relationships to predict solar wind speed () at 1 AU, based on an inverse relation…

Estimating Total Open Heliospheric Magnetic Flux

S. Wallace, C. N. Arge, M. Pattichis +2

Over the solar-activity cycle, there are extended periods where significant discrepancies occur between the spacecraft-observed total (unsigned) open magnetic flux and that determi…
