Figure 9: This figure shows the apparent horizons (actually MOTSs) for a spherically symmetric
numerical evolution of a black hole accreting a narrow shell of scalar field, the 800.pqw1 evolution of
Thornburg [155]. Part (a) of this figure shows (here labelled ) for a set of equally-spaced
times between and , while Part (b) shows the corresponding MOTS radius and
the Misner–Sharp [111], [112, Box 23.1] mass internal to each MOTS. Notice how two new
MOTSs appear when the local minimum in touches the line, and two existing MOTS
disappear when the local maximum in touches the line.
