Session 5 - Accretion and Outflows in YSOs.
Display session, Wednesday, January 07
We investigate the temperature structure and emergent spectral energy distribution of flared disks around Classical T Tauri stars. The radiation transfer is performed using a Monte Carlo radiation transfer code that we have developed to calculate the radiative equilibrium temperature distribution in dusty circumstellar environments of arbitrary geometry. Further modifications to our code will enable us to determine the degree of flaring in passive and active accretion disks. For the present, we investigate disks with a fixed density structure and degree of flaring. The temperature structure (radially and vertically) is calculated for different disk masses with the source of photons being from the star and accretion luminosity liberated in the disk. We are thus able to determine the relative contributions of stellar and accretion heating and calculate the emergent flux spectrum as a function of viewing angle and compare them with previous approximate solutions for flat and flared disks.
