Lucienne Divan, (September 2, 1920 – December 21, 2015) was a French astrophysicist, who spent her career at theInstitut d'astrophysique de Paris.[1] Divan worked on the spectral and luminosity classification of stars and on interstellar absorption.[2]
Divan was born inSainte-Radegonde-en-Touraine,Indre-et-Loire. A student of theÉcole normale supérieure de jeunes filles,[3] Lucienne Divan passed her examination in physics (first, 1945),[4] then pursued her career at theInstitut d'astrophysique de Paris from 1949, where she joinedDaniel Barbier andDaniel Chalonge.[5] When she retired, she moved to theHaute-Provence Observatory; she died on December 21, 2015, atSaint-Michel-l'Observatoire.[6]
WithBarbier andChalonge, Lucienne Divan contributed to the development of the three-dimensional stellar spectroscopic classification system called Classification of the IAP or BCD (for Barbier-Chalonge-Divan). This system was based on the spectro-photometric properties of theBalmer discontinuity in stellar spectra from a series of articles published in theAnnals of Astrophysics entitled "Researches on stellar continuous spectra." The BCD classification system for stars is not utilized today, scientists prefer theMK spectral classification system.[citation needed] Divan also published on the spectral properties of particular stars like Be stars, and particular variable stars likeV533 Hercules andFG Sagittae.[7]
Lucienne Divan is the author and co-author of 74 articles listed in the NASA/ADS bibliography.[8]
