Chromospheric Heating: conduction fronts (I)

Forbes & Malherbe (1986)
Forbes, Malherbe & Priest (1989)

Electrons are heated as they diffuse through

the conduction front.

Fronts stand in front of slow-mode shocks

For efficient heating the thermal thickness

of the slow shock must exceed the height of the flare loop (~ 5 x 104 km):

T = 10 MK, n ? 2x1010 cm-3, v|| ? 50km/s,
cp = 2.07x108 cm2s-2K-1 ?

w = 9 x 104 km
