Teacher-Researcher at IPSA, Associate Researcher at IMCCE Paris Observatory


Vincent ROBERT (using ROBERT-PÉLISSIER) was born in Créteil, France, in 1982. Currently Teacher-Researcher at Institut Polytechnique des Sciences Avancées IPSA since 2011, and Associate Researcher at Institut de Mécanique Céleste et de Calcul des Éphémérides IMCCE of Paris Observatory, under inter-institutional agreement. He received the M.Sc. equivalence degree from IPSA in 2006 in Space System Design, and the Ph.D. degree from Paris Observatory in 2011 in Astronomy and Astrophysics.

His researches are focusing on high-precision astrometry to improve planetary system dynamics, with a specialization for the sub-micrometric digitization of old astro-phographic plates: Natural satellites, Planets, Small bodies, and Stars.

He worked as an Astrometry specialist in the framework of the european FP7 ESPaCE project, under grant agreement n°263466. This poject aimed at strengthening collaborations and developments for new knowledges, technologies and products for the scientific community. The final products were ephemerides and reference systems for natural satellites and space probes. Calculation of new and high-accurate astrometric positions of planets and satellites to fit the most recent dynamical models.

He is now Head and PI of New Astrometric Reduction for Old Observations NAROO program. This program aims at selecting old astro-phtographic plates(1890-1998) for which a new reduction would provide original and precious data for the understanding and evlution modelization of systems: natural satellites, asteroids, and comets, in particular. First works used UCAC reference star catalogs, and last studies demonstrated the high interest in digitizing plates (Robert 2011, Robert et al. 2011, 2014, 2015, 2016). However, the main justification of the program has been the arrival of Gaia-DR2 and Gaia-DR3 catalogs and their astrometric accuracy in positions and proper motions for star references (1 mas over one century). While former star catalogs did not allow to measure plates realized before the 60's due to their positioning accuracy, Gaia-DR2 and Gaia-DR3 releases definitely solve this issue. Thus, all old observations could now be analyzed with the best accuracy, making obsolete all published data. A non-exhaustive list of possibilities is: new astrometric positions of planets and satellites to improve ephemerides, pre-discoveries and new astrometric positions of asteroids, TNOs and NEOs, pre-discoveries and new astrometric positions of comets, analysis of variable Be stars... Fields of action are numerous and justify the technical needs of the project.

Vincent ROBERT is also Head of Space, Launchers and Satellites ELS course option at IPSA. He teaches Space Mechanics, Astrometry, Fundamental Astronomy, and Satellite Design. He is support of IPSA'ONE student Association, and he is an elected member at the Administration Coucil.
