Stellar-Atlas: Simulation Dataset of Stellar Evolution across Mass and Metallicity (v1.0)

Stellar-Atlas is a detailed stellar evolution database generated using the MESA (Modules for Experiments in Stellar Astrophysics) code. It covers over 2350 simulations across masses ranging from 0.5 to 900 M☉ and metallicities Z = 0.0001 to 0.04.

The database includes:

• HR diagrams, core temperature-density plots, and other diagnostic graphs
• Evolution to hydrogen and helium exhaustion phases
• ZAMS analysis and Gaia DR3 observational comparison
• Batch automation scripts, plotting utilities, and inlist generators

This dataset supports theoretical stellar evolution studies, teaching, and Gaia-based comparison research.
