Antonia Maury
Antonia Caetana De Paiva Pereira Maury ( born March 21, 1866 in Cold Spring -on-Hudson, New York, † January 8, 1952 ) was an American astronomer and a niece of Henry Draper.
Maury worked at the Harvard College Observatory (HCO ), where they observed stellar spectra and in 1897 a catalog published by classifications (Spectra of Bright Stars Photographed with the 11- inch Draper Telescope as part of the Henry Draper Memorial. Annals of Harvard College Observatory, vol. 28, pp.1 -128 ). Edward Charles Pickering, director of HCO at this time, their system of classification and explanation of different line widths did not agree, and she left the HCO.
Ejnar Hertzsprung realized the importance of their classifications and related their system to distinguish in his system between giant stars and dwarf stars.
1908 Maury returned back to the HCO and remained there for several years. In 1933 she published the spectroscopic analysis of the double star Beta Lyrae ( The Spectral Changes of Beta Lyrae, Annals of Harvard College Observatory, vol. 84, no 8).
The lunar crater Maury is named after her and the oceanographer Matthew Fontaine Maury.
