Project PHaEDRA - Dorrit Hoffleit - O-stars, P-Cyngi stars. #A

At Harvard College Observatory (now the Center for Astrophysics | Harvard & Smithsonian), women computers studied glass plate photographs of the night sky. Here they catalogued stars, identifying variables, interpreting stellar spectra, counting galaxies, and measuring the vast distances in space. Several of them made game-changing discoveries in astronomy and astrophysics. In these books, follow the work of Dorrit Hoffleit, who studied variable stars during her time at Harvard, before running the star cataloging program at Yale and becoming the director of the Maria Mitchell Observatory on Nantucket. Interested in historical women? Love astronomy? Help us transcribe the work of the Harvard Observatory's women computers and see which stars shine the brightest. Have questions?

Project PHaEDRA - Evelyn F. Leland - Search for variables; measures #31 or 32

At Harvard College Observatory (now the Center for Astrophysics | Harvard & Smithsonian), women computers studied glass plate photographs of the night sky. Here they catalogued stars, identifying variables, interpreting stellar spectra, counting galaxies, and measuring the vast distances in space. Several of them made game-changing discoveries in astronomy and astrophysics. In these books, follow the work of Evelyn F. Leland who worked extensively on stellar spectra, finding objects with unual spectral lines, and discovered many new variable stars. Interested in historical women? Love astronomy?
