Karine Perraut
French astronomer
From Wikipedia, the free encyclopedia
Karine Rousselet-Perraut is a French astronomer at Grenoble Alpes University, affiliated with the Institute for Planetary sciences and Astrophysics, Grenoble (IPAG).[1]
Research
Perraut defended her doctorate in 1995 at Paul Cézanne University, directed by Farrokh Vakili.[2] Her astronomical training concerned the development of scientific instrumentation, with a thesis modeling the effects of polarization on optical interferometry in astronomy.[2][3]
Her subsequent research has used optical and infrared interferometry to study protoplanetary disks, through observations on the Very Large Telescope in Chile.[3] She has also used the Very Large Telescope to study the orbital precession of the star S2 around Sagittarius A*, the black hole at the center of the Milky Way, confirming the consistency of its motion with the theory of general relativity.[4]
Recognition
Perraut was one of the leaders of the GRAVITY instrument of the Very Large Telescope interferometer, which received the 2019 La Recherche prize for its observations of Sagittarius A*.[5]
Perraut received a CNRS Silver Medal in 2024.[3]
