🌠 Star Evolution Simulator

Modeling stellar evolution stages using Python

---

🎯 Purpose & Scope

This project simulates stellar evolution from main sequence to late stages. It calculates changes in luminosity, radius, and temperature based on stellar mass, using both theoretical and empirical models.

• Compute stellar lifetime for different masses.
• Simulate luminosity and temperature changes over time.
• Visualize evolution on the Hertzsprung–Russell (H–R) diagram.
• Supports bilingual outputs (Turkish / English).

🧮 Scientific Model

The simulator follows simplified analytic relationships from stellar physics:

tₛ ≈ 10¹⁰ × (M / M☉)⁻²·⁵  years

Where:

• M: stellar mass
• M☉: solar mass
• tₛ: approximate stellar lifetime

This formula reflects how massive stars evolve faster than smaller ones.
