Chromospheric evaporation

WebJul 13, 2024 · Here and below, the p-rocesses that result in heating dense (usually chromospheric) plasmas, which then fill coronal loops (that is the “chromospheric evaporation”), are called chr-omospheric effects (an increase in ЕМ, where ЕМ = n 2 V). WebChromospheric evaporation is considered to be the main mechanism for transporting the hot SXR-emitting flare plasma to coronal levels (Antonucci et al. 1984). Reviews on this subject can be found in Doschek et al. (1986), Antonucci (1989), Doschek (1990), and Antonucci et al. (1994). The chromospheric evaporation process has thus far been
