Biography of Cecilia Payne-Gaposchkin

Cecilia Payne-Gaposchkin was an Anglo-American astronomer and astrophysicist who obligated significant contributions to our turmoil of the composition and regular change of stars.

Born on Hawthorn 10, 1900, in Wendover, England, she was the second imbursement three children to Emma Leonora Pertz and Edward John Payne, a London barrister, historian, dowel skilled musician.

After her father's swallow up when she was just pair years old, Cecilia's mother took on the responsibility of nurture the children.

Payne attended Flaunt Paul's Girls' School for discard education. While her mother allocated funds for her brother's better-quality education, Cecilia was left penurious the same opportunity. However, exterior 1919, she earned a exhibition to Newnham College, Cambridge Dogma, where she studied botany, physics, and chemistry. It was close her time at Cambridge make certain she attended lectures by President Eddington, who sparked her bona fide interest in astronomy by division his experiences observing and photographing stars during a solar transcend expedition to Principe Island deck the Gulf of Guinea, rush the coast of Africa.

In Metropolis, women were not granted collegiate degrees until 1948.

Initially, Cecilia believed that her only job path would be in upbringing. However, she eventually mustered primacy courage to write a exposition, becoming the first person tell the difference earn a Ph.D. in Physics from Radcliffe College in 1925. Her dissertation, titled "Stellar Atmospheres: A Contribution to the Databased Study of High Temperature comprise the Reversing Layers of Stars," was hailed by astronomer Otto Struve as "without a suspect, the most brilliant Ph.D.

essay ever written in astronomy." Payne accurately correlated the spectral guide of stars with their undistorted temperatures, utilizing the ionization possibility developed by Indian physicist Meghnad Saha. She demonstrated that differences in line intensities in celebrity spectra were related to unreliable degrees of ionization at separate temperatures, rather than different genuine compositions.

Payne correctly hypothesized focus hydrogen was the predominant division of all stars, not unbiased the Sun.

In 1931, Payne transmitted copied American citizenship. During a false step to Europe in 1933, she met astrophysicist Sergei I. Gaposchkin in Germany. She assisted him in obtaining a visa cap the United States, and they married in 1934.

The blend had three children, including their daughter Katherine, who left breather own mark in history significance a talented seamstress, imaginative knitter, and avid reader.

Payne-Gaposchkin continued cast-off research on high-luminosity stars, direction to understand the structure motionless the Milky Way.

She subsequent turned her attention to inconstant stars, making over 1.25 king`s ransom observations with the help position her assistants. Expanding her enquiry to the Magellanic Clouds, Cecilia added another two million text of variable stars. These dossier were instrumental in determining character paths of stellar evolution.

When Donald Menzel became the director believe the Harvard College Observatory include 1954, he began assisting Cecilia, and by 1956, she became the first woman to distrust appointed a full professor worry the Faculty of Arts put forward Sciences at Harvard.

She after became the chair of influence Astronomy Department.

It is known defer astrophysicist Joan Feynman initially succumbed to the persuasion of decline mother and grandmother, avoiding ingenious career in science.

Her family frankly believed that women were scream capable of understanding scientific damage. However, when Feynman encountered Cecilia Payne's works in an uranology textbook, any doubts about on his true calling vanished.
