Water (H2O) is one of the most abundant molecules in the interstellar medium. In addition to being a primordial ingredient in the emergence of life, this species plays...

Low mass stars, like our Sun, are born from the collapse of a molecular cloud. The matter falls in the center of the cloud, creating a protoplanetary disk surrounding...

This work is devoted to the experimental investigation of the high temperature kinetics and spectroscopy of astrophysical gases. A versatile and existing High Enthalpy...

Polycyclic aromatic hydrocarbons (PAHs) play a major role in the physics and chemistry of photodissociation regions (PDRs) in our galaxy. In these environments, the...

The first stages of star formation are accompanied by an evolution of the chemistry, starting from simple molecules in cold dark clouds to the detection of complex...

This thesis studies the formation mechanisms and the composition of Titan's aerosols analogs, so called tholins. The study of the gas phase allowed identifying several...

Molecular lines are used to trace the structure of the interstellar medium and the physical conditions of the gas in different environments, from high-z galaxies to...
