Raphael Marschall

Raphael Marschall is a planetary physicist and post-doctoral researcher at the Laboratoire J.-L. Lagrange of the Observatoire de la Côte d’Azur (Nice, France). Previously, he worked at the Southwest Research Institute (USA) and the International Space Science Institute (Switzerland), completing his PhD in Planetary Science at the University of Bern. His research focuses on small Solar System bodies, including comets and asteroids, with a particular emphasis on understanding their evolution and formation through analysis of spacecraft data from missions like Rosetta and Lucy.

Education:

• PhD in Planetary Science, University of Bern (2017)

Research Interests:

• Cometary and asteroidal activity
• Protoplanetary disk evolution
• Planetesimal formation mechanisms
• Collisional dynamics of minor bodies

His work integrates observational data with advanced modeling to explore how small bodies preserve clues about the early Solar System. Recent projects include studying comet 67P/Churyumov-Gerasimenko’s coma and proposing the ORIGO mission concept to investigate primordial planetesimals.

Publications: Recent work spans cometary composition analysis, protoplanetary disk modeling, and mission concepts. Key themes include refractory-to-ice ratios in comets, inflationary disk phases, and collisional strength of Jupiter Trojans. These studies contribute to understanding how planetesimals formed and evolved in the early Solar System.

Grants & Labs: Involved in interdisciplinary collaborations, including ESA mission proposals like ORIGO. No specific grants or lab affiliations listed in current texts.
