Comparison between models Linlow (yellow line) and Loutlow (red line). The reference model (ref, blue line) corresponds to a Z = 1 Z⊙ star with Ṁstart = 1 × 10−8 M⊙ yr−1. The stellar luminosity is artificially reduced by 25% in the inner 1 AU (Linlow) and outside 1 AU (Loutlow). Panel a shows the evolution of the accretion rate. The dotted black line shows the termination criterion used in our simulations of Ṁ = 10−11 M⊙ yr−1. Panel b shows the temperature structure of the initial disk model. For model Linlow the inner disk region is cooler compared to the reference model, and for model Loutlow the outer disk region is cooler. The dotted black line shows the ambient temperature of 20 K.
