Title: Multidimensional Models of Type Ia Supernova Nebular Spectra: Strong Emission Lines from Stripped Companion Gas Rule Out Classic Single-degenerate Systems

Abstract

The classic single-degenerate model for the progenitors of Type Ia supernova (SN Ia) implies that the supernova ejecta should be enriched with solar-like abundance material stripped from the companion star. Spectroscopic observations of normal SNe Ia at late times, however, have not resulted in definite detection of hydrogen. In this Letter, we study line formation in SNe Ia at nebular times using non-LTE spectral modeling. We introduce, for the first time, multidimensional radiative transfer calculations of SNe Ia with stripped material mixed in the ejecta core, based on hydrodynamical simulations of ejecta–companion interaction. We suggest that interaction models with main-sequence companions produce significant Hα emission at late times, ruling out these types of binaries being viable progenitors of SNe Ia. We also predict significant He i line emission at optical and near-infrared wavelengths for both hydrogen-rich or helium-rich material, providing an additional observational probe of stripped ejecta. We produce models with reduced stripped masses and find a more stringent mass limit of M st ≲ 1 × 10 -4 M of stripped companion material for SN 2011fe.

Figures / Tables:

Figure 1 Figure 1: Properties of the MS38 model at 200 days past explosion, zoomed in to show the region of mass stripped from the companion. Panel (A) shows the deposition of energy from 56Co decay throughout the ejecta, strongest in the region of stripped material at low velocities into which gamma-raysmore » have penetrated from surrounding 56Co-rich regions. Panel (B) shows the calculated fraction of neutral hydrogen to total hydrogen. Dark blue regions contain less than 1% H by mass. The region near the core has high density, and thus strong recombination. Panel (C) shows the synthetic optical spectrum of the MS38 model. Hα is prominent next to the normal forbidden iron and cobalt features, and permitted He I lines are also visible. Panel (D) shows the synthetic NIR spectrum of the MS38 model. The fiducial model from Botyánszki & Kasen (2017) is included in black for reference. Dotted lines identify the following transitions: [Fe II] 12.257 μm, H I 1.2820 μm (Pβ), [Fe II] 1.6440 μm, and H I 1.8750 μm (Pα). He I emission is also prominent at 1.085 μm. Line profiles in the MS38 model are more peaked than in the fiducial model, and narrow hydrogen Paschen emission dominates the NIR spectrum.« less
