About this app

Stellar Evolution & the H-R Diagram is an interactive high-school Earth science app for exploring how surface temperature, luminosity, and mass shape a star’s life. Adjust temperature and luminosity to place a star on the H-R diagram, compare luminosity and lifetime across different masses, and follow paths ending as a white dwarf, neutron star, or black hole.

Use cases

  • Students learning stellar evolution and the H-R diagram
  • Teachers demonstrating main-sequence relationships in class
  • Learners comparing stellar mass, luminosity, and lifetime
  • Anyone reviewing supernova remnants and stellar final stages

Features

  • Interactive H-R diagram with adjustable surface temperature and luminosity
  • Main-sequence band and current-star position visualization
  • Mass controls comparing luminosity and lifetime with the Sun
  • Evolution paths for light, medium, and heavy stars
  • Mission-based activities with reset and next controls
