Prof. Vidali’s Astrophysics and Surface Science Research Laboratory

Astrophysics & Surface Science

SU News article snipProf. Vidali’s research is in Astrophysics (formation of molecules in the interstellar medium and in planetary environments) and in Surface Science (interaction of atoms and molecules with surfaces of solids). Prof. Vidali’s research has been written up in ScienceNews, Today’s Science, Scientific American Online, The Washington Post – online, Popular Mechanics, Nature News – online, Chemical Engineering News, Il Sole 24 Ore, and others. The National Science Foundation has awarded Professor Gianfranco Vidali a three-year, $736,600 grant to study how molecules stick, diffuse and depart dust grains (“stardust”) in the densest region of interstellar space—matter in the space between star systems.

Current projects

Experiments: study of processes of adsorption, diffusion and desorption of atoms, radicals and molecules on/in ices and dust grain analogs in simulated interstellar and planetary environments. Theory: Interaction of hydrogen atoms with graphene. Simulation of processes of molecule formation in interstellar medium environment using data obtain from the laboratory.

Motivation

Molecular hydrogen, the most abundant molecule in the universe, is formed mostly on interstellar grains; the effort to find how molecular hydrogen forms reflects the importance of this molecule in astrophysics and astrochemistry: molecular hydrogen aids the collapse of a cloud that eventually will become a star, and it intervenes – either neutral or charged – in most reactions leading to other molecules that have been found in space. The other molecule we are interested in, water, is made by the interaction of hydrogen and oxygen. Again, most of the water found in space is formed on dust grains. How water forms on grains and how it is retained on them is important in astrobiology and in understanding how water was incorporated in planets like the Earth. Furthermore, we are studying how atoms and molecules diffuse in amorphous water ice, the analog of ices coating stardust, in order to understand how reactants reacts and form molecules in interstellar ices.
