A truly distorted star?

• “observed true photospheric distortion with negligible envelope contribution”

  • Hα spectrum from same time + model: emission estimated ≤ 3% across whole line ═> envelope emits ≤ 12% of photospheric continuum
  • Yudin (2001) reported zero intrinsic polarization
  • distance 44.1 ± 1.1 pc
  • equatorial radius 12.0 ± 0.4 R
  • max polar radius 7.7 ± 0.2 R
