What did Antonia Maury change in stellar classification?

Her system introduced finer distinctions within stellar spectral classes. She published this detailed classification work in 1897.

Why is Antonia Maury's classification historically important?

Maury treated differences within stellar spectra as meaningful instead of using only broad categories. Her work helped establish a more detailed way to compare and classify stars.

Was Antonia Maury an astronomer or a human computer?
