Fizzy water ice in space: CO adsorption, binding energies and its fate in a protoplanetary disk
Alicja Bulik, V. Bariosco, E. Mates-Torres +4
CO2 is the third most abundant ice component found on dust grains in star-forming regions and a common ingredient of exoplanet atmospheres. Characterization of its adsorption prope…
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…
FAUST XXIX. OCS line emission: a new method for measuring the luminosity of embedded protostars in binary systems
Guillaume Saury, Vittorio Bariosco, Cecilia Ceccarelli +19
The luminosity of embedded protostars is commonly measured via observations of the dust continuum spectral energy distribution from millimetre to infrared wavelengths. However, thi…
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…
Atomistic insights on prebiotic phosphorylation of methanol from Schreibersite (Fe2NiP) corrosion: ab-initio computational study
Stefano Pantaleone, Giulia De Gasperis, Marta Corno +3
The prebiotic history of phosphorus is a matter of debate in the scientific community: its origin, how it landed on Earth, the selective speciation of the phosphate, and its inclus…
