POPCORN: A comparison of binary population synthesis codes

TL;DR

This paper compares three binary population synthesis codes to understand how assumptions and physical inputs affect their results, highlighting the importance of input choices in modeling binary star populations.

Contribution

It provides a systematic comparison of binary population synthesis codes, emphasizing the impact of physical assumptions on their outputs.

Findings

Results are similar when assumptions are equalized.

Differences mainly stem from varying physical inputs.

Physical input choices significantly influence synthesis outcomes.

Abstract

We compare the results of three binary population synthesis codes to understand the differences in their results. As a first result we find that when equalizing the assumptions the results are similar. The main differences arise from deviating physical input.
