Michael Marsset

Postdoctoral Associate

Research Description

Michael Marsset is an astronomer trying to decipher the history of our Solar System through the study of small celestial bodies: asteroids and comets. These past decades, the idea that these objects’ present location is the result of orbital migrations rather than their true formation location has progressively emerged, implying some asteroids could be comets, and some comets could be Trans-Neptunian Objects. Michael’s research consists in characterizing the composition (surface mineralogy and internal structure) of these different populations in order to determine possible genetic links between them, establish their relationship to Earth's impactors (meteorites and interplanetary dust), and investigate their past orbital evolution. At MIT, his work will focus on the large MITHNEOS spectroscopic survey of Near-Earth Objects led by Francesca DeMeo and Rick Binzel.

Michael did his PhD at the Laboratoire d’Astrophysique de Marseille (LAM, France) and the European Southern Observatory (ESO, Chile). During his previous post-doc at Queen’s University Belfast (UK), he studied the colors of the outermost Solar System objects, and the surface morphology of the largest main-belt asteroids.
