Imaging evidence for solar wind outflows originating from a CME footpoint
Juraj Lörinčík, Jaroslav Dudík, Guillaume Aulanier +2
We report on the Atmospheric Imaging Assembly (AIA) observations of plasma outflows originating in a coronal dimming during the 2015 April 28th filament eruption. After the filamen…
Multi thermal atmosphere of a mini solar flare during magnetic reconnection observed with IRIS
Reetika Joshi, Brigitte Schmieder, Akiko Tei +4
The Interface Region Imaging Spectrograph(IRIS) with its high spatial and temporal resolution brings exceptional plasma diagnostics of solar chromospheric and coronal activity duri…
The role of small-scale surface motions in the transfer of twist to a solar jet from a remote stable flux rope
Reetika Joshi, Brigitte Schmieder, Guillaume Aulanier +2
Jets often have a helical structure containing ejected plasma that is both hot and also cooler and denser than the corona. Various mechanisms have been proposed to explain how jets…
A case-study of multi-temperature coronal jets for emerging flux MHD models
Reetika Joshi, Ramesh Chandra, Brigitte Schmieder +4
Context: Hot coronal jets are a basic observed feature of the solar atmosphere whose physical origin is still being actively debated. Aims: We study six recurrent jets occurring in…
Electric current evolution at the footpoints of solar eruptions
Krzysztof Barczynski, Guillaume Aulanier, Miho Janvier +2
Electric currents play a critical role in the triggering of solar flares and their evolution. The aim of the present paper is to test whether the surface electric current has a sur…
