The simulation of SN2009ip bolometric light curves

The direct method of measuring cosmological distances relies on observations of the growth period of superluminous supernovae light curves. These supernovae can be explained by a strong shock wave propagation through the dense circumstellar matter. The direct method assumes that the thin dense shell formed under such conditions is spherically symmetric. However, multidimensional instabilities can break this symmetry. This article presents the simulation of SN2009ip, which has been successfully applied for the direct method, using the radiation hydrodynamics code, FRONT. It was shown that a simple model for SN2009ip correctly reproduces both the bolometric light curve as well as the dynamics of the dense shell. Furthermore, this dense shell remains spherically symmetric at least during the growth period of the light curve.
