"Super-Kilonovae" from Massive Collapsars as Signatures of Black Bole Birth in the Pair-instability Mass Gap

Description

Introduction

This zenodo repository contains data of the collapsar model calculations presented in the paper(linked below) together with the Jupyter notebook to reproduce the figures presented in the paper. The notebook also provides details on how to extract the required information from the data files. All the notations and quantity names follow from the paper and additional information is provided as text in the notebook.

The code and data files were developed by Aman Agarwal and Daniel Siegel. This information is free to use (open access, creative commons license) and we ask everyone who uses it to report bugs (aagarwal1@perimeterinstitute.ca) and to share further development based on this code, for the benefit of everyone else.

Data:
In this work, we take stellar models at the time of collapse and implement the collapsar fallback model on them. Two datasets of such stellar models were used for calculations in the paper.

Heger 2000 models: Heger, Langer & Woosley 2000, Presupernova Evolution of Rotating Massive Stars. I. Numerical Method and Evolution of the Internal Stellar StructureApJ 528, 368, https://2sn.org/stellarevolution/rotation/

This repository contains collapsar model calculations for these two datasets in two separate zipped folders. Naming conventions of collapsar model calculations follow those of the original progenitor stellar models.
