New developments in theoretical modelling of SN 1987A.

Recent developments in modeling SN 1987A are summarized, including the progenitor's evolution, explosive nucleosynthesis, optical, X- and gamma-ray light curves, and dust formation. The distribution of heavy elements in the ejecta is inferred from the light curves. The plateau-like peak of the optical light curve is well reproduced if hydrogen is mixed into the deep core. The progenitor's blue-red-blue evolution and N abundance suggest that the progenitor's hydrogen-rich envelope had mass of 7-11 solar masses and was almost completely mixed.
