| 内容記述 | We investigate the two-temperature model of the Advection Dominated Accretion Flow (ADAF) around a supermassive black hole. Electron temperature is determined from the local balance between energy transfer from ions through Coulomb collisions and radiative cooling via bremsstrahlung, synchrotron radiation and inverse Compton scattering. Appling our model to Sgr A*, we evaluate the corresponding spectrum emitted from the whole disk. It is found that the resulting spectrum is well fitted to the observed one when the mass accretion rate is in the range (3.6-7.2) x10^-8 M_sun yr^-1, which is in agreement with the value derived from polarized emission at radio wavelength. | |||||
