SN2023ixf: ultraviolet-to-infrared radiative-transfer modeling of the nebular-phase evolution until 1000 days

Alexei V. Filippenko, Claudia Gutierrez, K. Azalee Bostroem, Lluis Galbany, Luc Dessart, Stefano Valenti, Thomas G. Brink, Weikang Zheng, Wynn V. Jacobson-Galan

SN2023ixf's nebular light curve to 1000 days requires dust formation in the cold dense shell plus enhanced gamma-ray escape after 200 days.

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

Matching the V-band light curve requires invoking both enhanced gamma-ray escape and dust formation after ~200d, first in the CDS and eventually in the inner ejecta as well.

C2weakest assumption

The assumption that the same ejecta parameters (7-8 Msun, 1.2e51 erg, 0.05 Msun of 56Ni) that matched the photospheric phase continue to apply without modification throughout the nebular phase to 1000 days.

C3one line summary

Radiative-transfer models of SN2023ixf require a 0.2 solar-mass cold dense shell plus rising dust mass to match its nebular-phase UV-optical-IR evolution to 1000 days.
