Propagation of untwisting solar jets from the low-beta corona into the super-Alfvénic wind: Testing a solar origin scenario for switchbacks (2024)
Journal Article
Touresse, J., Pariat, E., Froment, C., Aslanyan, V., Wyper, P. F., & Seyfritz, L. (2024). Propagation of untwisting solar jets from the low-beta corona into the super-Alfvénic wind: Testing a solar origin scenario for switchbacks. Astronomy & Astrophysics, 692, Article A71. https://doi.org/10.1051/0004-6361/202452019

Context. Parker Solar Probe’s (PSP) discovery of the prevalence of switchbacks (SBs), localised magnetic deflections in the nascent solar wind, has sparked interest in uncovering their origins. A prominent theory suggests these SBs originate in the l...

A Model for Flux Rope Formation and Disconnection in Pseudostreamer Coronal Mass Ejections (2024)
Journal Article
Wyper, P. F., Lynch, B. J., DeVore, C. R., Kumar, P., Antiochos, S. K., & Daldorff, L. K. S. (2024). A Model for Flux Rope Formation and Disconnection in Pseudostreamer Coronal Mass Ejections. The Astrophysical Journal, 975(2), Article 168. https://doi.org/10.3847/1538-4357/ad7941

Coronal mass ejections (CMEs) from pseudostreamers represent a significant fraction of large-scale eruptions from the Sun. In some cases, these CMEs take a narrow jet-like form reminiscent of coronal jets; in others, they have a much broader fan-shap...

Solar Eruptions in Nested Magnetic Flux Systems (2024)
Journal Article
Karpen, J. T., Kumar, P., Wyper, P. F., DeVore, C. R., & Antiochos, S. K. (2024). Solar Eruptions in Nested Magnetic Flux Systems. Astrophysical Journal, 966(1), Article 27. https://doi.org/10.3847/1538-4357/ad2eaa

The magnetic topology of erupting regions on the Sun is a key factor in the energy buildup and release, and the subsequent evolution of flares and coronal mass ejections (CMEs). The presence/absence of null points and separatrices dictates whether an... Read More about Solar Eruptions in Nested Magnetic Flux Systems.
