Results for the self-regulated disk models with an initially molecular gas (Table 4), plus species abundances and heating/cooling rates for the reference case S1 (self-regulated disk with central source of 1 M_⊙ and an accretion rate of 10^-1 M_⊙ yr^-1). The top panel shows gas surface density as a function of radius. We refer to the caption of Fig. 2 for the description of the other panels.
