Constraints on pre-SN outbursts from the progenitor of SN 2023ixf using the Large Binocular Telescope

The progenitor of SN 2023ixf was a \sim10^{4.8} to 10^{5.0}\rm ~L_\odot star (\sim9 to 14 \rm~M_\odot at birth) obscured by a dusty \dot{M} \simeq 10^{-5} \rm~M_\odot~yr^{-1} wind with a visual optical depth of \tau_V \simeq 13. This is required by the progenitor SED, the post-SN X-ray and H\alpha luminosities, and... Show more
