The Solar System was born 4.5 billion years ago from a cold clump of a molecular cloud of the Milky Way. Astrochemistry is a powerful tool to elucidate (1) what happened to the first phases of the Solar System formation and (2) how they might have in

The local interstellar medium (ISM) is an open and complex system, driven by the combined effects of turbulence, magnetic field, gravity, and ultraviolet photons.The rising amount of data collected by spectrometers from radio to ultraviolet (UV) wave

The star formation process usually proceeds with protoplanetary disks. These disks contain a mixture of gas, accounting for 99 % of the disk mass, and of solid particles called dust grains (1 % of the disk mass). These grains, initially at sub-micro

As a part of interstellar dust, polycyclic aromatic hydrocarbons (PAHs) in so-called photodissociation regions (PDRs) are processed by the interaction with ultraviolet (UV) photons that are emitted by hot stars. After absorption of a UV photon, an is

The deposition of energy in the form of electronic excitations in molecules condensed on cold surfaces (10-100 K) can lead to the desorption of some of these molecules. This basicsurface science process has consequences in a variety of fields, two of
