Simulating the Negative Jet Feedback Mechanism in Common Envelope Jet Supernovae

Abstract We use the stellar evolution code MESA to study negative jet feedback mechanism in common envelope supernovae (CEJSNe), which a neutron star (NS) launches jets of red supergiant (RSG). find that reduces mass accretion rate be χ j ≃ 0.04–0.3 times without operation jets. mimic effect on RSG by depositing energy carry into zones outside NS orbit. The deposition inflates envelope, therefore reducing density vicinity, turn cycle. In calculating above values for coefficient (the further reduction rate) , we adopt canonical ratio power actual 0.1, and results numerical simulations show fraction 0.1–0.5 Bondi–Hoyle–Lyttleton rate.
