Comparison of gas temperature distributions in models with different thermal evolution schemes. First and second rows: gas temperatures in (ThES2)-model 2v and (ThES1)-model 2v, respectively. Third, fourth, and last rows: gas temperatures in (beta=3)-model 2v, (beta=10)-model 2v, and (beta=30)-model 2v, respectively. In the β-models the gas and dust temperatures are the same. The time is counted from the instance of disk formation. The scale bar is in log Kelvin.
