TL;DR

This paper predicts gravitational wave signals from core collapse supernovae for progenitors of 9.6, 15, and 25 solar masses, considering different metallicities and non-rotating conditions.

Contribution

It provides detailed gravitational wave emission predictions for supernova progenitors across a range of masses and metallicities, based on three new simulation models.

Findings

Gravitational wave strain evolution over time is characterized for each progenitor.

Spectral decomposition reveals frequency components of the GW signals.

Predicted characteristic strains inform future detection prospects.

Abstract

We present gravitational wave emission predictions based on three core collapse supernova simulations corresponding to three different progenitor masses. The masses span a large range, between 9.6 and 25 Solar masses, are all initially non-rotating, and are of two metallicities: zero and Solar. We compute both the temporal evolution of the gravitational wave strains for both the plus and the cross polarizations, as well as their spectral decomposition and characteristic strains.
