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…
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…
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…
The prebiotic pathway from P-bearing iron meteorites to phosphates by DFT modeling
Stefano Pantaleone, Marta Corno, Albert Rimola +2
Among the biogenic macroelements, phosphorus is the one bringing the most fascinating and unsolved mysteries for what concern its prebiotic history. It possibly landed on Earth as…
Unraveling the Interface Chemistry between HCN and Cosmic Silicates by the Interplay of Infrared Spectroscopy and Quantum Chemical Modeling
Niccolò Bancone, Rosangela Santalucia, Stefano Pantaleone +4
Understanding the interaction between hydrogen cyanide (HCN) and silicate surfaces is crucial for elucidating the prebiotic processes occurring on interstellar grain cores, as well…
The GRETOBAPE gas-phase reaction network: the importance of being exothermic
Lorenzo Tinacci, Simón Ferrada-Chamorro, Cecilia Ceccarelli +5
The gas-phase reaction networks are the backbone of astrochemical models. However, due to their complexity and non-linear impact on the astrochemical modeling, they can be the firs…
Where does the energy go during the interstellar NH formation on water ice? A computational study
Stefano Ferrero, Stefano Pantaleone, Cecilia Ceccarelli +3
In the coldest (10--20 K) regions of the interstellar medium, the icy surfaces of interstellar grains serve as solid-state supports for chemical reactions. Among their plausible ro…
Theoretical distribution of the ammonia binding energy at interstellar icy grains: a new computational framework
Lorenzo Tinacci, Aurele Germain, Stefano Pantaleone +3
The binding energies (BE) of molecules on the interstellar grains are crucial in the chemical evolution of the interstellar medium (ISM). Both temperature programmed desorption (TP…
Structures and Properties of Known and Postulated Interstellar Cations
Lorenzo Tinacci, Stefano Pantaleone, Andrea Maranzana +3
Positive ions play a fundamental role in the interstellar chemistry, especially in cold environments where chemistry is believed to be mainly ion-driven. However, in contrast with…
H2 formation on interstellar grains and the fate of reaction energy
Stefano Pantaleone, Joan Enrique-Romero, Cecilia Ceccarelli +4
Molecular hydrogen is the most abundant molecular species in the Universe. While no doubts exist that it is mainly formed on the interstellar dust grain surfaces, many details of t…
Chemical desorption versus energy dissipation: insights from ab-initio molecular dynamics of HCO formation
Stefano Pantaleone, Joan Enrique-Romero, Cecilia Ceccarelli +3
Molecular clouds are the cold regions of the Milky Way where stars form. They are enriched by rather complex molecules. Many of these molecules are believed to be synthesized on th…
