Master’s 2 students in Astrophysics and the Cosmos, Fields and Particles at the Haute-Provence Observatory

The visit by students in the Master’s 2 programs in “Astrophysics” and “Cosmos, Fields, and Particles” from Montpellier and Lyon to the Haute-Provence Observatory took place this year from September 22 to 26, 2025.

This year, 21 students were able to use three OHP telescopes as well as the IRiS telescope at LabEx OCEVU to carry out seven projects (including the study of an exoplanet using the transit method, the characterization of the orbits of binary stars, and the study of a spiral galaxy). During their stay, the students also had the opportunity to visit the 193-cm telescope and the ELODIE spectrograph, with which Swiss astronomers Michel Mayor and Didier Queloz discovered the first exoplanet orbiting a main-sequence star 30 years ago, in 1995.
