A possible mechanism for over luminous type Ia supernovae explosions inspired by dark matter

TL;DR

This paper proposes a new dark matter-inspired mechanism where white dwarfs can exceed the Chandrasekhar limit, potentially explaining super luminous Type Ia supernovae, and suggests observable quantities to probe dark matter properties.

Contribution

It introduces a model of dark matter accretion in white dwarfs that leads to super-Chandrasekhar masses, offering a novel explanation for super luminous supernovae.

Findings

Dark white dwarfs can surpass the Chandrasekhar limit due to dark matter accretion.

Observable quantities like redshift and moment of inertia are sensitive to dark matter distribution.

The model provides potential methods to probe dark matter properties through supernova observations.

Abstract

Dark matter is believed to be a major component of our universe. In this paper we propose a new mechanism based on dark matter inspired super-Chandrasekhar mass white dwarf to explain the recent observation of super luminous type Ia supernovae explosions. Our calculation shows when a white dwarf accretes enough dark matter, due to the Pauli exclusive principle between fermionic dark matter particles, the mass of corresponding dark white dwarf (which means the white dwarf mixed with dark matters) can significantly exceeds the Chandrasekhar limit. Moreover, we investigate some physical observable quantities, such as the redshift and moment of inertia of the dark white dwarf and found that these quantities are sensitive to the dark matter particle's distributions and thus can be potentially used to probe the relevant information of dark matter particles in the future.
