Numerical simulations find that off-center carbon burning in accreting CO white dwarfs produces substantial Si and S abundances that depend on initial carbon content, supporting the double WD merger scenario for SN 2021yfj-like events.

Elemental Abundances from Off-center Carbon Burning in Accreting CO White Dwarfs: Implications for SN 2021yfj-like events
Numerical simulations find that off-center carbon burning in accreting CO white dwarfs produces substantial Si and S abundances that depend on initial carbon content, supporting the double WD merger scenario for SN 2021yfj-like events.
