Asymmetrical thermonuclear supernovae triggered by the tidal disruption of white dwarfs

Luc Dessart, Pavan Vynatheya, R\"udiger Pakmor, Taeho Ryu

Tidal disruptions of white dwarfs by intermediate-mass black holes can produce thermonuclear supernovae that appear highly asymmetrical depending on the viewing angle.

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 recover the typical rise times and peak luminosities of SNe Ia, but with an extremely strong viewing-angle dependence of both light curves and spectra. At nebular times, isolated strong emission lines like [Ca ii] λλ 7291, 7323 may appear both displaced and skewed by many 1000 km s^{-1}.

C2weakest assumption

The hydrodynamics and nuclear network in AREPO accurately capture the tidal compression, heating, and partial burning without missing effects such as magnetic fields, general relativity, or resolution-dependent mixing that could alter the 56Ni yields and asymmetry for the explored impact parameters.

C3one line summary

Tidal disruptions of 0.6 solar mass white dwarfs by 500 solar mass black holes can produce asymmetrical thermonuclear supernovae with 56Ni fractions from 1% to 82% depending on impact parameter and strong viewing-angle dependence in light curves and spectra.
