Physical models for type I supernovae and the distance scale,nt of .Ni which can be ejected in models which match the observations. The luminosity at maximum light in these models is proportional to the amount of nickel ejected, and hence limits can be set on the distance scale and H.. If the carbon deflagration model is correct, then 0.4 < H./(100 km/s/Mpc) <0.7.

Supernova observations at McDonald observatory,NGC 3227, NGC 3625, and NGC 4419 are compared with those of SN 1981b in NGC 4536 to quantitatively illustrate both the homogeneity of Type I spectra at similar epochs and the differences in detail which will serve as a probe of the physical processes in the explosions. Spectra of the recent supernov

Spectropolarimetry of supernovae,ovae.Lines with P Cygni profiles produced by resonance scattering in an expanding atmosphere with non-circular isophotes should show a linear polarization in excess of that in the continuum. Thus, spectropolarimetry offers a means of measuring the roundness of a supernova envelope and assessing the
