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
