Alfvenic Perturbations in a Sunspot Chromosphere Linked to Fractionated Plasma in the Corona
D. Baker, M. Stangalini, G. Valori +7
In this study, we investigate the spatial distribution of highly varying plasma composition around one of the largest sunspots of solar cycle 24. Observations of the photosphere, c…
The Magnetic Environment of a Stealth Coronal Mass Ejection
Jennifer O'Kane, Cecilia Mac Cormack, Cristina H. Mandrini +4
Interest in stealth coronal mass ejections (CMEs) is increasing due to their relatively high occurrence rate and space weather impact. However, typical CME signatures such as extre…
20 Years of ACE Data: How Superposed Epoch Analyses Reveal Generic Features in Interplanetary CME Profiles
F. Regnault, M. Janvier, P. Démoulin +4
Interplanetary coronal mass ejections (ICMEs) are magnetic structures propagating from the Sun's corona to the interplanetary medium. With over 20 years of observations at the L1 l…
Active-Region Tilt Angles from White-Light Images and Magnetograms: The Role of Magnetic Tongues
M. Poisson, P. Démoulin, C. H. Mandrini +1
The presence of elongations in active region (AR) polarities, called magnetic tongues, are mostly visible during their emergence phase. AR tilts have been measured thoroughly using…
Can Sub-photospheric Magnetic Reconnection Change the Elemental Composition in the Solar Corona?
Deborah Baker, Lidia van Driel-Gesztelyi, David H. Brooks +6
Within the coronae of stars, abundances of those elements with low first ionization potential (FIP) often differ from their photospheric values. The coronae of the Sun and solar-ty…
