抄録

Spectropolarimetry is one of the most powerful methods to study the multi-dimensional geometry of extragalactic supernovae (SNe). We have performed spectropolarimetric observations of Type Ib/c SNe with the Subaru telescope. The data clearly show the "loop" in the Stokes Q - U plane. By performing 3D radiative transfer simulations, we show that the loop is clear evidence for 3D, non-axisymmetric geometry of SNe. We also summarize the properties of the line polarization of Type Ib/c SNe. We find that a stronger line tends to show a higher line polarization. This effect must be corrected to compare the polarization of different lines or different objects.
