# A minority view on the majority: A personal meeting summary on the explosion mechanism of supernovae

## TL;DR

This paper argues that supernova explosions are primarily driven by jets rather than neutrinos, challenging the mainstream view, and emphasizes the importance of considering alternative mechanisms in supernova research.

## Contribution

It presents a critical perspective supporting jet-driven supernova explosions and the core degenerate scenario for SN Ia, contrasting with the neutrino-driven model.

## Key findings

- Simulations did not produce CCSNe explosions via neutrinos.
- Jet feedback mechanism explains high explosion energies.
- Advocates for open-mindedness in supernova explosion theories.

## Abstract

In the meeting SN 1987A 30 years later, I presented my minority view that the majority (or even all) of core collapse supernovae (CCSNe) are driven by jets rather than by neutrinos, and that the majority of type Ia supernovae (SN Ia) reach their explosion via the core degenerate scenario. New simulations presented at the meeting did not achieve an explosion of CCSNe. I critically examine other arguments that where presented in support of the neutrino-driven model, and present counter arguments that support the jet-driven explosion mechanism. The jets operate via a negative jet feedback mechanism (JFM). The negative feedback mechanism explains the explosion energy being several times the binding energy of the core in most CCSNe. At the present time when we do not know yet what mechanism explodes massive stars and we do not know yet what evolutionary route leads white dwarfs to explode as SN Ia, we must be open to different ideas and critically examine old notions.
