Figure 19: Meridional plane density contours from the SMS collapse simulation of Saijo, Baumgarte, Shapiro, and Shibata [208]. The contour lines denote densities r = rc × d(1-i/16), where rc is the central density. The frames are plotted at (t/t D, r c, d)=(a)(5.0628 × 10- 4, 8.254 × 10 -9, - 7 10), (b)(2.50259, -4 1.225 × 10, -5 10), (c)(2.05360, - 3 8.328 × 10, -7 5.585 × 10), (d)(2.50405, 3.425 × 10- 2, 1.357 × 10-7), respectively. Here t, tD, and M0 are the time, dynamical time (V~ ------- = R3e/M, where Re is the initial equatorial radius and M is the mass), and rest mass. (Figure 15 of [208]; used with permission.)
