Where is the base of the Transition Region? Evidence from TRACE, SDO, IRIS and ALMA observations
Alissandrakis, Costas E.
Classic solar atmospheric models put the Chromosphere-Corona Transition Region (CCTR) at ∼ 2 Mm above the τ5000 = 1 level, whereas radiative MHD (rMHD) models place the CCTR in a wider range of heights. However, observational verification is scarce. In this work we review and discuss recent results from various instruments and spectral …
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…
