7 p, 485.0 KB Formation of Complex Organic Molecules on Interstellar CO Ices? Insights from Computational Chemistry Simulations / Ferrero, Stefano (Universitat Autònoma de Barcelona. Departament de Química) ; Ceccarelli, Cecilia (Université Grenoble Alpes) ; Ugliengo, Piero (Università degli Studi di Torino. Dipartimento di Chimica and Nanostructured Interfaces and Surfaces) ; Sodupe Roure, Mariona (Universitat Autònoma de Barcelona. Departament de Química) ; Rimola, Albert (Universitat Autònoma de Barcelona. Departament de Química)
The carbon (3P) atom is a reactive species that, according to laboratory experiments and theoretical calculations, condensates with interstellar ice components. This fact is of uttermost importance for the chemistry in the interstellar medium (ISM) because the condensation reaction is barrierless, and the subsequent species formed are still reactive given their open-shell character. [...]

17 p, 1.7 MB Binding energies of interstellar relevant S-bearing species on water ice mantles : a quantum mechanical investigation / Perrero, Jessica (Universitat Autònoma de Barcelona. Departament de Química) ; Enrique-Romero, Joan (Universitat Autònoma de Barcelona. Departament de Química) ; Ferrero, Stefano (Universitat Autònoma de Barcelona. Departament de Química) ; Ceccarelli, Cecilia (Centre National de la Recherche Scientifique. Université Grenoble Alpes. Institut de Planétologie et d'Astrophysique de Grenoble) ; Podio, Linda (Istituto Nazionale di Astrofisica. Osservatorio Astrofisico di Arcetri) ; Codella, Claudio (Istituto Nazionale di Astrofisica. Osservatorio Astrofisico di Arcetri) ; Rimola, Albert (Universitat Autònoma de Barcelona. Departament de Química) ; Ugliengo, Piero (Università degli Studi di Torino. Dipartimento di Chimica)
Binding energies (BEs) are one of the most important parameters for astrochemical modeling determining, because they govern whether a species stays in the gas phase or is frozen on the grain surfaces. [...]

12 p, 4.1 MB Where does the energy go during the interstellar NH3 formation on water ice? a computational study / Ferrero, Stefano (Universitat Autònoma de Barcelona. Departament de Química) ; Pantaleone, Stefano (Università degli Studi di Torino. Dipartimento di Chimica) ; Ceccarelli, Cecilia (Centre National de la Recherche Scientifique. Institut de Planétologie et d'Astrophysique de Grenoble) ; Ugliengo, Piero (Università degli Studi di Torino. Dipartimento di Chimica) ; Sodupe Roure, Mariona (Universitat Autònoma de Barcelona. Departament de Química) ; Rimola, Albert (Universitat Autònoma de Barcelona. Departament de Química)
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 roles, that of third body is advocated, in which the reaction energies of surface reactions dissipate throughout the grain, stabilizing the product. [...]

Departamento de Astronomía) ; Cortes, Paulo (National Radio Astronomy Observatory) ; Rao, Ramprasad (Academia Sinica (Taiwan). Institute of Astronomy and Astrophysics)
With the aim of characterizing the dynamical processes involved in the formation of young protostars, we present high-angular-resolution ALMA dust polarization observations of the Class 0 protostellar cores Serpens SMM1, Emb 8(N), and Emb 8. [...]

Departament de Física)
The Chelyabinsk meteorite is a highly shocked, low porosity, ordinary chondrite, probably similar to S- or Q-type asteroids. Therefore, nanoindentation experiments on this meteorite allow us to obtain key data to understand the physical properties of near-Earth asteroids (NEAs). [...]
