The "Planeto" team is part of the LMD laboratory and IPSL institute. The team studies the physics, dynamics and chemistry of all types of planetary atmospheres, both in the Solar System and on exoplanets, and investigates the evolution of these systems and the origins of life. These activities are supported by the development of models, in the same way as for the study of the Earth: Global Climate Models, but also smaller-scale models (large eddy simulations, mesoscale models). The team is also involved in space research, providing support for instrumental development, mission preparation and data analysis. Although the main objects of study are the atmospheres of the planets and telluric satellites of the solar system (Mars, Venus, Titan), the team also studies the atmospheres of the giant planets (Saturn, Jupiter, Uranus, Neptune), past climates to explore the evolution of these various atmospheres, the finer and colder atmospheres of the outer reaches of the solar system (Pluto, Triton), and last but not least the diversity of atmospheres of exoplanets (from temperate rocky planets to hot Jupiters).

Research Projects

Our main research projects are:

  • Development of a hierarchy of sophisticated numerical climate models for the ten solar system planetary atmospheres (from Venus to Pluto), for paleoclimates, and for all types of exoplanetary atmospheres. More info here.
  • Development of the Planetary Climate Databases, for Mars and Venus.
  • Participations to space mission projects and observations. This includes missions to Mars (TGO, InSight, Hope, Mars Express, etc.), Venus (EnVision, DAVINCI, etc.), Pluto (New Horizons), and observations of exoplanets (JWST, ELT@ANDES).
