Anisotropy of core-collapse supernovae effected by AGN disks

TL;DR

This paper investigates how the dense environments of AGN disks influence the anisotropy of core-collapse supernovae, revealing that migration acceleration significantly impacts explosion asymmetry and luminosity.

Contribution

It constructs equilibrium models considering pressure gradients and migration, and computes light curves for various progenitors and AGN disk parameters, highlighting migration effects.

Findings

Migration acceleration impacts supernova anisotropy more than pressure gradients.

Anisotropic luminosities are stronger at larger radii in AGN disks.

More massive SMBHs suppress anisotropy and decrease luminosity.

Abstract

Active galactic nucleus (AGN) disk provide dense environments to influence on the star formation, evolution, and migration. In AGN disks, pressure gradients and migration accelerations could create the anisotropy of the core-collapse supernovae (CCSNe) when the massive stars explode at the end of their lives. In this study, we construct the equilibrium equations by considering the above two factors and then compute the light curves for three types of progenitor stars at different locations of AGN disks for the different supermassive black hole (SMBH) masses, accretion efficiencies, explosion energies, and masses of ejecta. The results show that the migration acceleration has more significant effects on the anisotropic explosions than the pressure gradients of the AGN disks. The anisotropic luminosities are pronounced at large radii, and massive SMBHs would suppress the anisotropy and reduce the total luminosity.
