Photocleavage of aliphatic C--C bonds in the interstellar medium

Autor: Tajuelo-Castilla, Guillermo, Mendieta-Moreno, Jesús I., Accolla, Mario, Sobrado, Jesús M., Canola, Sofia, Jelínek, Pavel, Ellis, Gary J., Martín-Gago, José Ángel, Santoro, Gonzalo

Ultraviolet (UV) processing in the insterstellar medium (ISM) induces the dehydrogenation of hydrocarbons. Aliphatics, including alkanes, are present in different interstellar environments, being prevalently formed in evolved stars; thus, the dehydro

Structure, stability and optical absorption spectra of small Ti$_n$C$_x$ clusters: a first-principles approach

Autor: Gámez-Valenzuela, Sergio, Alonso, Julio A., Santoro, Gonzalo, Martínez, José I.

Titanium-carbide molecular clusters are thought to form in the circumstellar envelopes (CSEs) of carbon-rich Asymptotic Giant Branch stars (AGBs) but, to date, their detection has remained elusive. To facilitate the astrophysical identification of th

INFRA-ICE: an ultra-high vacuum experimental station for laboratory astrochemistry

Autor: Santoro, Gonzalo, Sobrado, Jesús. M., Tajuelo-Castilla, Guillermo, Accolla, Mario, Martínez, Lidia, Azpeitia, Jon, Lauwaet, Koen, Cernicharo, José, Ellis, Gary J., Martín-Gago, José Ángel

Laboratory astrochemistry aims at simulating in the laboratory some of the chemical and physical processes that operate in different regions of the Universe. Amongst the diverse astrochemical problems that can be addressed in the laboratory, the evol

Silicon and hydrogen chemistry under laboratory conditions mimicking the atmosphere of evolved stars

Autor: Accolla, Mario, Santoro, Gonzalo, Merino, Pablo, Martínez, Lidia, Tajuelo-Castilla, Guillermo, Vázquez, Luis, Sobrado, Jesús M., Agúndez, Marcelino, Jiménez-Redondo, Miguel, Herrero, Víctor J., Tanarro, Isabel, Cernicharo, José, Martín-Gago, José Ángel

Silicon is present in interstellar dust grains, meteorites and asteroids, and to date thirteen silicon-bearing molecules have been detected in the gas-phase towards late-type stars or molecular clouds, including silane and silane derivatives. In this

Report

The chemistry of cosmic dust analogues from C, C$_2$, and C$_2$H$_2$ in C-rich circumstellar envelopes

Autor: Santoro, Gonzalo, Martínez, Lidia, Lauwaet, Koen, Accolla, Mario, Tajuelo-Castilla, Guillermo, Merino, Pablo, Sobrado, Jesús M., Peláez, Ramón J., Herrero, Víctor J., Tanarro, Isabel, Mayoral, Álvaro, Agúndez, Marcelino, Sabbah, Hassan, Joblin, Christine, Cernicharo, José, Martín-Gago, José Ángel

Interstellar carbonaceous dust is mainly formed in the innermost regions of circumstellar envelopes around carbon-rich asymptotic giant branch (AGB) stars. In these highly chemically stratified regions, atomic and diatomic carbon, along with acetylen
