Hertzsprung–Russell Diagram
This interactive simulator explores Hertzsprung–Russell Diagram in Astronomy & The Sky. Schematic HR regions; drag a star to see main sequence, giants, white dwarfs. Use the controls to change the scenario; watch the visualization and any graphs or readouts to connect the model with lectures, labs, and homework.
Who it's for: Best once you already know the basic definitions and want to build intuition. Typical context: Astronomy & The Sky.

How it works
The HR diagram plots stellar luminosity (or absolute magnitude) against effective temperature (or spectral type). Most stars spend the longest time fusing hydrogen on the main sequence; giants and white dwarfs are later stages for many stars.
