definition A supernova type whose spectrum contains hydrogen lines. Compared with Type I supernovae, its light curve has a broader peak at maximum and dies away more rapidly. The magnitudes are smaller, ranging from M_V = -12 to -13.5, and the ejecta have lower velocities (about 5,000 km/sec). These supernovae, which result from the final evolution of massive stars, have three main divisions: Type II-P, Type II-L, and Type II-n.
