Scientific paper

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 testing the spherical symmetry of supernovae and assessing the reliability of Baade method distances without invoking assumptions about the polarization introduced by intervening dust.
