A spectroscopic measurement of high velocity spray plasma from an M-class flare and coronal mass ejection
Young, Peter R.
The M1.5-class flare and associated coronal mass ejection (CME) of 16 February 2011 was observed with the Extreme ultraviolet Imaging Spectrometer on board the Hinode spacecraft. Spray plasma associated with the CME is found to exhibit a Doppler blue-shift of 850 km s-1 - one of the largest values reported from spectroscopy of the solar…
Coronal spectroscopy: Probing sources of slow solar wind in active regions, and the early phases of solar flares
Harra, Louise K.
Coronal spectroscopy has pushed forward the understanding of physical processes in all phenomena on the Sun. In this review we concentrate specifically on plasma parameters measured in sources of the slow solar wind in active regions and the early phases of solar flares. These topics are a key part of the science goals of the Solar Orbiter mission…
