Conclusions

SLIDE 40

Conclusions 1) Dissipative corona purely cooled by Compton scattering heats up to ~ 1 keV on the base of radiative transfer. 2) Maximum optical depth of such corona:

  • ptical depth in hydr. eq. ~ 5

3) The optical depth of soft corona is increasing when gas pressure is reduced for instance when magnetic pressure is increasing. 4) For optical depth ~ 20 , but maybe there is another mechanism to low down the gas pressure ????
