How To Detect & Characterize Exoplanets - Dr. Marc Ollivier, Institut d'Astrophysique Spatiale-Paris
Exoplanets are planets that orbit other stars. Over six thousand exoplanets have been detected since the first one was discovered thirty-five years ago. Very few have been seen directly. Most are known by their effects on the motion of their parent stars. Observation, particularly from space telescopes, has enabled the detection of numerous planetary systems and the characterization of the different planets that compose them. During this presentation, Dr. Ollivier will focus on the potential of photometry and spectrophotometry of planetary transits. Dr. Ollivier will explain this method and the different exoplanet observables it reveals. He will show how two highly complementary observatories, the James Webb Space Telescope and the European ARIEL spacecraft, will very soon be able to provide us with information that will give us a better understanding of the formation and evolution of exosystems.
Dr. Olivier is an astronomer at the Institut d'Astrophysique Spatiale d'Orsay (IAS - CNRS / Univ Paris-Saclay, France), where he contributes to the development of space instrumentation for the detection and characterization of exoplanets. Program co-sponsored by the St. Louis Astronomical Society and the NASA Missouri Space Grant Consortium at Washington University. Also a virtual program.
