Figure 31: Meridional plane density contours from the SMS collapse simulation of Saijo, Baumgarte, Shapiro, and Shibata [259]. The contour lines denote densities ρ = ρc × d(1−i∕16), where ρc is the central density. The frames are plotted at (t∕tD, ρc, d) = (a) (5.0628 × 10–4, 8.254 × 10–9, 10–7), (b) (2.50259, 1.225 × 10–4, 10–5), (c) (2.05360, 8.328 × 10–3, 5.585 × 10–7), (d) (2.50405, 3.425 × 10–2, 1.357 × 10–7). Here t, tD, and M0 are the time, dynamical time (∘ --3---- = R e∕M, where Re is the initial equatorial radius and M is the mass), and rest mass. (Figure 15 of [259]; used with permission.)
