Formation of formaldehyde through methanol-ice-mantle (CH3OH)10bombardment by OH+cation (2021)
(EDP Sciences, 2021-06-01)Context. Formaldehyde H2CO was the first organic polyatomic molecule discovered in the interstellar medium to have been detected in a variety of sources. However, pathways to synthesize this molecule under interstellar ... -
Article
Formation of H2on polycyclic aromatic hydrocarbons under conditions of the ISM: an ab initio molecular dynamics study (2024)
(Oxford University Press, 2023)Understanding how the H2 molecule is formed under the chemical conditions of the interstellar medium (ISM) is critical to the whole chemistry of it. Formation of H2 in the ISM requires a third body acting as a reservoir ... -

Formation pathways of complex organic molecules: OH•projectile colliding with methanol ice mantle (CH3OH)10 (2020)
(EDP Sciences, 2020-09-01)In this article, we simulated the collisions of an OH• projectile impacting on a methanol cluster formed by ten units of methanol to mimic an ice mantle (CH3OH)10. The chemical processes occurring after the impact were ... -
Article
Methanediol CH2(OH)2and hydroxymethyl CH2OH+: key organic intermediates on the path to complex organic molecules (2024)
(EDP Sciences, 2022)Context. Ab initio molecular dynamics simulations were carried out to study the formation pathways to complex organic molecules when a OH+ projectile hit an interstellar dust grain covered only by methanol molecules. The ... -
Article
Multi-scale view of star formation in IRAS 21078+5211: From clump fragmentation to disk wind (2021)
(EDP Sciences, 2021-03-01)Context. Star formation (SF) is a multi-scale process in which the mode of fragmentation of the collapsing clump on scales of 0.1-1 pc determines the mass reservoir and affects the accretion process of the individual ... -
