MESA Grid: Binary Evolution (M1=6.0, M2=4.0, Z=0.02)

Grid of Close-Binary Evolution Models

This dataset contains a grid of close-binary evolution models computed with the MESA (Modules for Experiments in Stellar Astrophysics) code, version r24.08.1. The primary objective is to investigate the dependence of binary interaction on the initial orbital period.

Model Configuration:

Physics and Assumptions:

Termination Criteria:

Calculations are terminated if:

  1. Roche-lobe overflow occurs at the very first timestep.
  2. The system undergoes overflow through the outer Lagrangian point (L2).

The setup is designed to isolate the role of the initial orbital period in determining the onset of mass transfer and the subsequent evolutionary regime.
