Answer
Spectral classification of stars is Fowler's contribution to astrophysics. He developed a system for classifying stars based on their spectra, which allowed astronomers to determine the temperature, luminosity, and chemical composition of stars. This system, known as the Fowler-Adams classification scheme, is still used today and has been instrumental in our understanding of stellar evolution.
