Constraints on the variable nature of the slow solar wind with the Wide-Field Imager on board the Parker Solar Probe
Spiros Patsourakos, Angelos Vourlidas, Alexander Nindos
In a previous work we analysed the white-light coronal brightness as a function of elongation and time from Wide-Field Imager (WISPR) observations on board the Parker Solar Probe (…
Understanding the deflection of the `Cartwheel CME': data analysis and modeling
Abril Sahade, Angelos Vourildas, Laura Balmaceda +1
We study the low corona evolution of the `Cartwheel' coronal mass ejection (CME; 2008-04-09) by reconstructing its 3D path and modeling it with magneto-hydrodynamic simulations. Th…
Parker Solar Probe: Four Years of Discoveries at Solar Cycle Minimum
N. E. Raouafi, L. Matteini, J. Squire +54
Launched on 12 Aug. 2018, NASA's Parker Solar Probe had completed 13 of its scheduled 24 orbits around the Sun by Nov. 2022. The mission's primary science goal is to determine the…
SuNeRF: Validation of a 3D Global Reconstruction of the Solar Corona Using Simulated EUV Images
Kyriaki-Margarita Bintsi, Robert Jarolim, Benoit Tremblay +8
Extreme Ultraviolet (EUV) light emitted by the Sun impacts satellite operations and communications and affects the habitability of planets. Currently, EUV-observing instruments are…
