Named in honor of Yvette Marie Josette (b. 1925), French spectroscopist who works mainly on infrared spectra of early-type stars. She has also contributed to the spectroscopy of galaxies, novae, planetary nebulae and comets. Near the end of her renowned career she became acting director of the Observatoire de Haute Provence. The planet is named also in honor of her husband, Henri Andrillat, who is a retired professor of astronomy and a prominent cosmologist. The couple now live in Toulouse.
