Abstract | SN 1994I in M 51 has provided light curves in various wavelength bands allowing a distinction between models of Type Ic supernovae. We present bolometric and monochromatic light curves of exploding C+O stars that form from ~13-15 M_sun_ stars through the losses of the H-rich and He envelopes in close binary systems. The slopes of the calculated light curves are sensitive to the models and found to be in excellent agreement with the observed light curves for the 0.9 M_sun_ ejecta model. A high interstellar reddening (A_V_ ~ 1.4 mag) is required. From the light curve fits, a distance modulus of 29.2+/-0.3 mag is derived for M 51. The ejected ^56^Ni mass is found to be 0.07_-0.025_^+0.035^ M_sun_. Possibilities to observe γ-rays from SN 1994I with CGRO are discussed. |
