Emmanuël Jehin


After completing a doctorate at the Astrophysics Unit of the University of Liege under the direction of Pierre Magain, which he finished in 2000, Emmanuël Jehin spent 7 years in Chile as an astronomer. He worked on the Very Large Telescope (ESO, Paranal site) in the science operations team and was the head of one of the observation instruments. As the VLT was very recent at the time, Emmanuël Jehin participated, with the first teams of astronomers, in the implementation of the system. Since 2007 he has returned to Belgium as a research associate at the F.R.S-FNRS and teaches a course on “the small bodies of the solar system” (comets, asteroids, meteorites…).

Emmanuël Jehin is specialized in te study of small bodies in the solar system and especially in the chemical composition of comets, these relics from the formation of the solar system. He is responsible for the cometary physics group of ULg which is composed of FNRS researchers and Doctoral students. Within the framework of the TRAPPIST project, which consists of two robotic telescopes installed in Chile and Morocco, the astrophysicist is the technical and scientific manager and principal investigator for comets. He is also the project manager of SPECULOOS, a Liege-based project for 4 robotic telescopes installed in Chile to research near Earth-like exoplanets, orbiting in the habitable zone of their red dwarf star. He is involved in the Rosetta mission of the ESA for the ground based monitoring of comet Churyumov-Gerasimenko, and he is involved in two new projects of space missions. The first, from NASA, will aim to bring back a comet sample to study it on Earth. The other, which is European, will send a small telescope into the asteroid belt to look forice outgassing, as well as detecting the small asteroids that are not detectable from Earth.

In parallel with this, Emmanuël Jehin is also very involved in the popularization of astronomy, especially within the Spa Astronomy Group which he founded with other enthusiasts in 1990 and which organizes several activities: courses for children, conferences, exhibitions, public observation sessions…
