The survivorship bias of protoplanetary disc populations - Internal photoevaporation causes an apparent increase in the median total disc mass with time

Fig. 2

Evolution of the accretion rate (blue) and mass (black) of a disc over time. The vertical yellow line indicates the instant when the gap opens, which triggers a steep decrease in $\dot{M}$ $\dot M$ . The red line marks the transition between accreting and non-accreting phases. The grey region corresponds to values of disc mass and accretion rate below the respective observational threshold.
