Laboratoire de Physique Stellaire et Planétaire

Laboratoire de Physique Stellaire et Planétaire is a research institution specializing in stellar and planetary physics with programs spanning observational astronomy, theoretical astrophysics, and laboratory experiments. The laboratory engages with international agencies, observatories, and universities to conduct studies relevant to stellar evolution, planetary atmospheres, and astrochemistry. Its activities intersect with missions, research centers, and scientific societies across Europe and beyond.

History

Founded amid postwar expansions in astrophysical research, the laboratory traces institutional roots to collaborations among observatories and universities similar to Observatoire de Paris, Max Planck Society, University of Cambridge, University of Oxford, and École Normale Supérieure. Early partnerships linked the laboratory to technical facilities inspired by projects at European Southern Observatory, Institut d'Astrophysique de Paris, Laboratoire d'Astrophysique de Bordeaux, CNRS, and CERN spin-offs in instrumentation. Over decades the group contributed to campaigns associated with Hubble Space Telescope, Gaia (spacecraft), SOHO, Rosetta (spacecraft), and Mars Express instrument teams, while researchers published with peers from Harvard University, Massachusetts Institute of Technology, California Institute of Technology, Max Planck Institute for Astronomy, and University of Tokyo.

Research and Focus Areas

The laboratory's research spans stellar structure and evolution, planetary atmospheres, magnetohydrodynamics, radiative transfer, and astrochemistry, interfacing with programs at NASA, European Space Agency, JAXA, ISRO, and Roscosmos. Work on stellar spectroscopy connects to datasets from Very Large Telescope, Keck Observatory, Subaru Telescope, Arecibo Observatory, and ALMA while theoretical efforts draw on methods developed at Institute for Advanced Study, Perimeter Institute, Princeton University, University of California, Berkeley, and University of Chicago. Planetary science projects engage with comparative studies involving Cassini–Huygens, Galileo (spacecraft), Voyager program, New Horizons, and Juno (spacecraft), and address atmospheric dynamics seen in Mars Reconnaissance Orbiter, Venus Express, Mercury Surface, Space Environment, Geochemistry and Ranging, and ExoMars. The laboratory also pursues laboratory spectroscopy and plasma experiments relevant to Comet Halley studies, Interstellar medium chemistry, and prebiotic processes alongside teams from Max Planck Institute for Extraterrestrial Physics, Royal Observatory, Edinburgh, Astrophysical Institute Potsdam, and Instituto de Astrofísica de Canarias.

Facilities and Instruments

Instrument development includes spectrometers, coronagraphs, polarimeters, and laboratory plasma chambers, with testbeds modeled after hardware used at European Southern Observatory, Large Binocular Telescope, Gran Telescopio Canarias, Institut d'Optique, and Laboratoire d'Optique Appliquée. The laboratory maintains computing clusters for radiative transfer and magnetohydrodynamic simulations comparable to resources at National Center for Supercomputing Applications, Argonne National Laboratory, Los Alamos National Laboratory, and NERSC centers, and uses detector technologies aligned with suppliers and groups such as Thales Group, Teledyne Technologies, CEA, ONERA, and Fraunhofer Society. Calibration and verification campaigns have been conducted in partnership with field sites like Pic du Midi Observatory, La Silla Observatory, Mauna Kea Observatories, Kitt Peak National Observatory, and Atacama Large Millimeter Array.

Collaborations and Partnerships

The laboratory collaborates with academic departments, national agencies, and international consortia including CNRS, INSU, University of Strasbourg, Aix-Marseille University, Université Grenoble Alpes, and research networks linked to European Research Council, Horizon Europe, COST, and Interreg. Partnerships extend to space mission teams and instrument consortia associated with ESA Science Programme, NASA Jet Propulsion Laboratory, SpaceX contractors for payload integration, Airbus Defence and Space, and industrial partners such as Thales Alenia Space and Safran. Collaborative science involves exchanges with institutes like Max Planck Institute for Solar System Research, Institut d'Astrophysique Spatiale, Laboratoire de Physique des Plasmas, Observatoire de la Côte d'Azur, and consortia behind projects such as PLATO (spacecraft), CHEOPS, TESS, and JWST.

Education and Outreach

Educational activities include graduate training, doctoral supervision, postdoctoral fellowships, and summer schools organized with universities and research centers including Sorbonne University, Ecole Polytechnique, ETH Zurich, University of Geneva, and Imperial College London. Outreach programs collaborate with museums and public institutions such as Cité des Sciences et de l'Industrie, Palais de la découverte, Smithsonian Institution, Royal Astronomical Society, and American Astronomical Society for exhibitions, lectures, and citizen science linked to projects like Zooniverse, Galaxy Zoo, and coordinated campaigns during events such as solar eclipse observations and International Astronomical Union initiatives.
