Spectra, the H-R diagram, and the life cycle of a star from birth to death. Ends with a real diagnosis — no name attached: What Happens to This One?
The Path Through Unit 4
Classify a set of real stars by spectral type and plot each one on an H-R diagram — building a quick-reference deck you'll use for the rest of the unit.
Storyboard or film a star's life cycle, birth to death, at a mass you choose — one wrong turn in the sequence changes the whole ending.
You're handed a star's spectrum, luminosity, and H-R diagram position — no name, no label. Determine its current life stage and predict its fate, and defend it with the data.
