Astrochemical Inheritance of Terrestrial Planets Water from Local Wet Silicates
Lise Boitard-Crépeau, Stefano Pantaleone, Cecilia Ceccarelli +3
The delivery of water to the inner Solar System rocky planets, including Earth, remains debated, as standard models assume that they formed from dry grains, inside the snowline of…
Carbon chain diversity in L1544 and IRAS 16293-2422: an astrochemical pathfinder study for the SKAO
Lisa Giani, Eleonora Bianchi, Anthony Remijan +12
Astrochemical observations have revealed a surprisingly high level of chemical complexity, including long carbon chains, in the earliest stages of Sun-like star formation. The orig…
The role of the pre-exponential factor on temperature programmed desorption spectra: A computational study of frozen species on interstellar icy grain mantles
S. Pantaleone, L. Tinacci, V. Bariosco +3
Temperature programmed desorption (TPD) is a well-known technique to study gas-surface processes, and it is characterized by two main quantities: the adsorbate binding energy and t…
Was Earth's water acquired locally during the earliest phases of the Solar System formation?
Lise Boitard-Crépeau, Cecilia Ceccarelli, Pierre Beck +2
The origin of the terrestrial water remains debated, as standard Solar System formation models suggest that Earth formed from dry grains, inside the snowline of the Proto-Solar Neb…
Gas-phase formation routes of dimethyl sulfide in the interstellar medium
Gabriella Di Genova, Nadia Balucani, Luca Mancini +3
Context: Dimethyl sulfide (DMS; CHSCH) is an organosulfur compound that has been suggested as a potential biosignature in exoplanetary atmospheres. In addition to its tenta…
A comprehensive study of the gas-phase formation network of HCN: theory, experiments, observations and models
Lisa Giani, Eleonora Bianchi, Martin Fournier +6
Cyanopolyynes are among the largest and most commonly observed interstellar Complex Organic Molecules in star-forming regions. They are believed to form primarily in the gas-phase,…
