A magnetic avalanche as the central engine powering a solar flare
L. P. Chitta, D. I. Pontin, E. R. Priest +17
Solar flares are the most powerful, magnetically driven, explosions in the heliosphere. The nature of magnetic energy release in the solar corona that heats the plasma and accelera…
Picoflares in the Quiet Solar Corona: Solar Orbiter Observations Halfway to the Sun
O. Podladchikova, A. Warmuth, L. Harra +33
X-ray observations of the Sun led Eugene Parker to propose nanoflares as the basic energy-release units that heat the solar corona. Decades later, Solar Orbiter's Extreme Ultraviol…
Coronal hole picoflare jets are progenitors of both fast and Alfvénic slow solar wind
L. P. Chitta, Z. Huang, R. D'Amicis +19
Solar wind, classified by its bulk speed and the Alfvénic nature of its fluctuations, generates the heliosphere. The elusive physical processes responsible for the generation of t…
Probing Solar Polar Regions
Yuanyong Deng, Hui Tian, Jie Jiang +45
The magnetic fields and dynamical processes in the solar polar regions play a crucial role in the solar magnetic cycle and in supplying mass and energy to the fast solar wind, ulti…
Active region upflows in various coronal structures and their coupling to the lower atmosphere
Yingjie Zhu, Louise Harra, Krzysztof Barczynski +13
Plasma upflows with a Doppler shift exceeding -10 km/s at active region (AR) boundaries are considered potential sources of the nascent slow solar wind. We investigate the driving…
First coordinated observations between Solar Orbiter and the Daniel K. Inouye Solar Telescope
Krzysztof Barczynski, Miho Janvier, Chris J. Nelson +8
Solar Orbiter and the Daniel K. Inouye Solar Telescope (DKIST) are two of the newest facilities available to the solar physics community. The first coordinated observations of the…
