Binary Evolution at the Extremes of Mass-Transfer Efficiency: Contact, Mergers, and Population Signatures (online data)

Authors: Jan Henneco, Utkarsh R. Basu, and Fabian R. N. Schneider Title: Binary Evolution at the Extremes of Mass-Transfer Efficiency: Contact, Mergers, and Population Signatures (online data) Journal: Astronomy & Astrophysics Year: 2026 arXiv: https://arxiv.org/abs/2608.05001 This Zenodo repository contains the online data needed to reproduce the `MESA` stellar structure and evolution models in Henneco et al. (2026), as well as the machine-readable version of Table B.1. The `MESA` template is split up in two folders; `lowmass_model_dir` and `massive_model_dir`. The latter is used for models where the initial total mass (m_1,i + m_2,i) is larger than 7 Msol. This is done since the lower-mass models benefit from a slightly different set of numerical inlist settings. `MESA` output will be provided upon reasonable request (dataset too large for Zenodo). Please contact Jan Henneco for such requests.
