Spectropolarimetry of SN 2023ixf Reveals Both Circumstellar Material and an Aspherical Helium Core

Spectropolarimetry of SN 2023ixf Reveals Both Circumstellar Material and an Aspherical Helium Core

We present multi-epoch optical spectropolarimetric and imaging polarimetric observations of the nearby Type II supernova (SN) 2023ixf discovered in M101 at a distance of 6.85 Mpc. The first imaging polarimetric observations were taken +2.33 days (60085.08 MJD) after the explosion, while the last ima...
