Using astrochemical models to simulate reactivity experiments on cold surfaces
Valeriia Sokolova, Basile Husquinet, Stephan Diana +7
The development of molecular complexity during stellar and planetary formation owes much to the interaction of gas and dust. When the first astrochemical models including solid-sta…
The evolution of complex organic molecules during star formation
Pierre Marchand, Audrey Coutens, Jean-Christophe Loison +3
Complex organic molecules (COMs) are thought to be the precursors of pre-biotic molecules and are observed in many protostellar sources. For this paper we studied the formation of…
Rate constants and product yields for the C + CH3CHO reaction at low temperatures
Kevin M. Hickson, Jean-Christophe Loison, Valentine Wakelam
Reactions involving atomic carbon in its ground electronic state, C(3P), play an important role in astrochemistry due to high C-atom abundance levels. Here we performed a kinetic i…
APE: An analytical protostellar environment to provide physical conditions to chemical models and synthetic observations
Pierre Marchand, Audrey Coutens, Antoine Espagnet +3
Chemical modeling and synthetic observations are powerful methods to interpret observations, both requiring a knowledge of the physical conditions. In this paper, we present the An…
Modelling methanol and hydride formation in the JWST Ice Age era
Izaskun Jiménez-Serra, Andrés MegÃas, Joseph Salaris +19
(Abridged) JWST observations have measured the ice composition toward two highly-extinguished field stars in the Chamaeleon I cloud. The observed extinction excess on the long-wave…
Molecular chemistry induced by J-shock toward supernova remnant W51C
Tian-Yu Tu, Valentine Wakelam, Yang Chen +2
Shock waves from supernova remnants (SNRs) have strong influence on the physical and chemical properties of molecular clouds (MCs). Shocks propagating into magnetized MCs can be cl…
