Results from blackbody fitting. The blue line indicates fitting to the interpolated optical light curves. The red crosses represent the fit parameters for the optical blackbody shown in Fig. 6. The diamonds indicate parameters associated with the IR blackbody, with dark green indicating fitting to NEOWISE MIR photometry and lighter green fitting to NOTCam NIR photometry. Top panel: Pseudo-bolometric luminosities implied from the blackbody fitting. The luminosities were calculated from the Stefan−Boltzmann law. The total luminosity is the sum of the IR and optical luminosities. At later times when we have no optical data, the total luminosity is simply the IR luminosity. Middle panel: Evolution of the temperature for the optical and IR blackbodies. Bottom panel: Evolution of the radius for the optical and IR blackbodies.
