Description

Cecilia Payne-Gaposchkin (1900-1979) was an English-American astronomer and astrophysicist whose work on stellar spectra led to the discovery that stars are composed primarily of hydrogen and helium.

Although she began her studies at the University of Cambridge, Payne soon realized that, as a woman, she had little
hope of a career in Britain. She moved to the United States and began graduate work at Harvard where she encountered the so-called Harvard Computers—a group of women hired by Harvard Observatory to classify and  catalogue every known star in the sky according to temperature and spectra.

Using data gathered by the Computers, Payne applied the ionization theory developed by Indian physicist Maghnad Saha to the puzzle of absorption lines—the black bands that appear at intervals along the spectra when starlight is broken down into its constituent colours. She concluded that these patterns indicate an abundance of hydrogen and helium in the stars—an idea contrary to the widely accepted belief that stars had the same elemental composition as  the earth. At first derided for her conclusions, she was persuaded to add a disclaimer to her thesis, saying that her results were “almost certainly not real.” Soon, however, the rest of the scientific community caught up and recognized her thesis as one of the most brilliant ever written in the field of astronomy.

Cecilia Payne went on to become a full professor and the first woman to head a department at Harvard. Academically active in research and teaching throughout her life, she was was inspiration for other women in traditionally male dominated fields of study. Recalling her own experience, she encouraged her students to be rigorous in their research, but then to have confidence in themselves. “I had given in to Authority when I believed I was right,” she confessed. “That is another example of How Not To Do Research. I note it here as a warning to the
young. If you are sure of your facts, you should defend your position.”
