Laboratory Astrophysics

Laboratory Astrophysics is one of the most recent disciplines of Astrophysics. It consists in performing laboratory experiments simulating the physical conditions of the interstellar medium and planetary atmospheres. The Rennes group use state-of-the art experiments in order to identify and characterize the molecules (spectroscopy) and the processes leading to their formation (chemical kinetics) in these extreme environments where the temperature varies from less than 10 K (- 263°C) to a few thousands of degrees !

Combustion, Plasma and Environment

The research of the Combustion, Plasma and Environment axis is focused on means of analyzing particle formation in these systems using synchrotron radiation and mass spectrometry, and fundamental research on Atomic and Molecular processes such as Dissociative Recombination and Electron Attachment of reactions relevant to these themes. In parallel are developed new research activities related to environmental questions, such as atmospheric fate of pollutants and in-field measurements of gaseous emissions from Green Algae on beaches. The applied activities of this axis include research on the degradation of electrical contacts by arcs induced between electrodes and the consequences of these arcs in starting fires.

Theory and Simulation

The team is involved in the theoretical study of elementary processes in Atomic and Molecular Physics, both on fundamental and applied points of view (molecular processes at ultralow temperatures, structure and dynamics of molecules, interactions between atoms and strong electromagnetic fields, aggregates, astrophysics, atmospheric physics,…).
