Cosmic-Ray induced desorption¶
from revision ad4d5779 (20 June 2017)
the switch
.true. ! computed_CR_DESORB_ratesallows the CR-induced rates to be computed depending on the actual grain size and temperature instead of assuming a radius of 0.1 micron and a dust grain temperature of 10K. The default values for the CR-induced desorption also assumes that the grain reaches a temperature of 70K upon a hit by a Fe-CR of 100 MeV. Ref. Hasegawa et al. 1993 MNRAS 261, 83, Shen et al. 2003 (A&A 415, 203S), Leger et al. 1985 (A&A 144, 147). The routines will compute the actual grain temperature attained after the CR hit and the evaporation rate using the Eads chosen by the user. The grains are cooled by water and CO ice evaporation and radiative cooling, which is efficient for large grains (>1 micron).
