Hydrogenation of acetaldehyde on interstellar ice analogs reveals limited destruction
Germán Molpeceres, Thanh Nguyen, Yasuhiro Oba +1
We sought to determine which are the main hydrogenation paths of acetaldehyde (CH3CHO). As a partially unsaturated molecule, CH3CHO can have links with more hydrogenated species, l…
Proposed importance of HOCO chemistry: Inefficient formation of CO from CO and OH reactions on ice dust
Atsuki Ishibashi, Germán Molpeceres, Hiroshi Hidaka +3
With the advent of JWST ice observations, dedicated studies on the formation reactions of detected molecules are becoming increasingly important. One of the most interesting molecu…
Formation of the interstellar sugar precursor, (Z)-1,2-ethenediol, through radical reactions on dust grains
Juan Carlos del Valle, Pilar Redondo, Johannes Kästner +1
In recent years, the continued detection of complex organic molecules of prebiotic interest has refueled the interest on a panspermic origin of life. The prebiotic molecule glycera…
In-Depth Exploration of Catalytic Sites on Amorphous Solid Water: I. The Astrosynthesis of Aminomethanol
Giulia M. Bovolenta, Gabriela Silva-Vera, Stefano Bovino +3
Chemical processes taking place on ice-grain mantles are pivotal to the complex chemistry of interstellar environments. In this study, we conducted a comprehensive analysis of the…
Methane Formation Efficiency on Icy Grains: Role of Adsorption States
Masashi Tsuge, Germán Molpeceres, Yuri Aikawa +1
Methane (CH4) is one of the major components of the icy mantle of cosmic dust prevalent in cold, dense regions of interstellar media, playing an important role in the synthesis of…
Enhanced formation of interstellar complex organic molecules on carbon monoxide ice
Germán Molpeceres, Kenji Furuya, Yuri Aikawa
We investigate the role of carbon monoxide ice in the chemical evolution of prestellar cores using astrochemical rate equation models. We constrain the ratios of the binding energi…
First detection in space of the high-energy isomer of cyanomethanimine: H2CNCN
David San Andrés, Víctor M. Rivilla, Laura Colzi +14
We report the first detection in the interstellar medium of -cyanomethanimine (HCNCN), the stable dimer of HCN of highest energy, and the most complex organic molecule ident…
