Radial variation of some disc properties at three different ages of 1 Ma, 2 Ma, and 3 Ma (from top to bottom). Panel a: temperature at the mid-plane. The dotted horizontal lines correspond to the vaporisation of ice (152 K), pyrolysis of kerogen (450 K), and oxidation of soot (~ 1200 K). Panel b: pressure at the mid-plane. Panel c: radial accretion velocity.
