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.
