Figure 5: Optimal hydrodynamic model. Panel a): the calculated B light curve ( solid line) compared with the observations of SN 2005cs obtained by Pastorello et al. (2006) ( open triangles) and Tsvetkov et al. (2006) ( open circles). Panels b) and c): the same as panel a) but for the V and R light curves. Panel d): calculated photospheric velocity ( solid line) is compared with photospheric velocities estimated from absorption minima of the He I 5876 Å line ( crosses) and the Fe II 5169 Å line ( open circles) measured by Pastorello et al. (2006). |

Figure 7: Bolometric light curve a), b), and c) and photospheric velocity d) of the hydrodynamic models in Table 1 compared with the empirical data of SN 2005cs (see legends of Figs. 4 and 5 for details). Dotted line is model EM1, dashed line is model EM2, thick solid line is model EM3, and thin solid line is model EM4. Mixed models EM3 and EM4 are shown by the corresponding dotted-dashed lines in panels b) and c). |
