CareerMargot has discovered and studied several binary asteroids with radar and optical telescopes. His discoveries include (87) Sylvia I Romulus, (22) Kalliope I Linus, S/2003 (379) 1, (702) Alauda I Pichi üñëm, and the binary nature of (69230) Hermes. In 2000, he obtained the first images of binary near-Earth asteroids and described formation of the binary by a spin-up process.[2] Margot and his research group have studied the influence of sunlight on the orbits and spins of asteroids, the Yarkovsky and YORP effects.[3][4][5] In 2007, Margot and collaborators determined that Mercury has a molten core from the analysis of small variations in the spin rate of the planet.[6][7] These observations also enabled a measurement of the size of the core based on a concept proposed by Stan Peale.[8][9] In 2012, Margot and graduate student Julia Fang analyzed Kepler space telescope data to infer the architecture of planetary systems.[10] They described planetary systems as "flatter than pancakes."[11] They also showed that many planetary systems are dynamically packed.[12] Since 2016, he has guided UCLA students in conducting searches for technosignatures with large radio telescopes.[13][14] Honors and awardsMargot was awarded the H. C. Urey Prize by the American Astronomical Society in 2004. The asteroid 9531 Jean-Luc is named after him.
