JWST spectroscopy of SN 2010da/NGC 300 ULX-1: a surviving star hidden by dust

Ben Davies, Dominic J. Walton, Emma R. Beasor, Marianne Heida, Nathan Smith, Ryan Lau

The donor star in SN 2010da has survived its outburst and returned to a heavily dust-obscured state.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

We conclude that the donor star is likely an AGB star that has survived and is now heavily enshrouded - having returned to a dust-obscured state following a transient post-outburst phase in which the system appeared as a red supergiant.

C2weakest assumption

That the radiative transfer modeling of the mid-IR SED uniquely identifies silicon carbide dust and that the measured bolometric luminosity of log(L/Lsun)=4.11 definitively indicates a surviving star rather than residual emission from other components or a failed supernova remnant.

C3one line summary

The donor star survived the 2010 outburst, returned to a dust-obscured AGB state, and is no longer visible as a red supergiant.
