A database of spectral energy distributions of progenitors of core-collapse supernovae

TL;DR

This paper introduces a comprehensive database of spectral energy distributions for progenitors of core-collapse supernovae, including both single and binary stars across various metallicities, masses, and orbital parameters.

Contribution

The paper provides the first extensive database of spec-SEDs and phot-SEDs for CCSN progenitors, covering a wide range of stellar and binary parameters for research use.

Findings

Database includes low-resolution spec-SEDs and phot-SEDs for progenitors.

Useful for studying parameters like metallicity, age, and mass.

Guidelines for fitting SEDs of binary progenitors are provided.

Abstract

This paper presents a database of the spectroscopic- and photometric- spectral energy distributions (spec-SEDs and phot-SEDs) of the progenitors of core-collapse supernovae (CCSNe). Both binary- and single-star progenitors are included in the database. The database covers the initial metallicity ($Z$) range of 0.0001--0.03, mass range of 8--25 \dsm{}, binary mass ratio range of 0--1, and orbital period range of 0.1--10000\,days. The low-resolution spec-SEDs and phot-SEDs of single- and binary-star CCSN progenitors are included in the database. These data can be used for studying the basic parameters, e.g., metallicity, age, initial and final masses of CCSN progenitors. It can also be used for studying the effects of different factors on the determination of parameters of CCSN progenitors. When the database is used for fitting the SEDs of binary-star CCSN progenitors, it is strongly suggested to determine the metallicity and orbital period in advance, while it is not necessary for single-star progenitors.
