The Significant Role of Hydrogen in the Formation of Silicon Carbide in Evolved Stars
Guillermo Tajuelo-Castilla, Gonzalo Santoro, Lidia Martínez +13
Cosmic dust is mainly formed in the atmospheres of evolved stars. In carbon rich stars, amorphous carbon along with silicon carbide are the main constituents of dust grains yet the…
Detection of Cosmic Fullerenes in the Almahata Sitta Meteorite: Are They an Interstellar Heritage?
Hassan Sabbah, Mickaël Carlos, Peter Jenniskens +4
Buckminsterfullerene, C60 , is the largest molecule observed to date in interstellar and circumstellar environments. The mechanism of formation of this molecule is actively debated…
The impact and recovery of asteroid 2018 LA
Peter Jenniskens, Mohutsiwa Gabadirwe, Qing-Zhu Yin +63
The June 2, 2018, impact of asteroid 2018 LA over Botswana is only the second asteroid detected in space prior to impacting over land. Here, we report on the successful recovery of…
Impact of metals on (star)dust chemistry: a laboratory astrophysics approach
Rémi Bérard, Kremena Makasheva, Karine Demyk +5
Laboratory experiments are essential in exploring the mechanisms involved in stardust formation. One key question is how a metal is incorporated into dust for an environment rich i…
The chemistry of cosmic dust analogues from C, C, and CH in C-rich circumstellar envelopes
Gonzalo Santoro, Lidia Martínez, Koen Lauwaet +13
Interstellar carbonaceous dust is mainly formed in the innermost regions of circumstellar envelopes around carbon-rich asymptotic giant branch (AGB) stars. In these highly chemical…
Astrochemical relevance of VUV ionization of large PAH cations
Gabi Wenzel, Christine Joblin, Alexandre Giuliani +7
As a part of interstellar dust, polycyclic aromatic hydrocarbons (PAHs) are processed by the interaction with vacuum ultraviolet (VUV) photons that are emitted by hot young stars.…
Photo-processing of astro-PAHs
Christine Joblin, Gabi Wenzel, Sarah Rodriguez Castillo +8
Polycyclic aromatic hydrocarbons (PAHs) are key species in astrophysical environments in which vacuum ultraviolet (VUV) photons are present, such as star-forming regions. The inter…
Identification of PAH Isomeric Structure in Cosmic Dust Analogues: the AROMA setup
Hassan Sabbah, Anthony Bonnamy, Dimitris Papanastasiou +3
We developed a new analytical experimental setup called AROMA (Astrochemistry Research of Organics with Molecular Analyzer) that combines laser desorption/ionization techniques wit…
VUV photo-processing of PAH cations: quantitative study on the ionization versus fragmentation processes
Junfeng Zhen, Sarah Rodriguez Castillo, Christine Joblin +7
Interstellar polycyclic aromatic hydrocarbons (PAHs) are strongly affected by the absorption of vacuum ultraviolet (VUV) photons in the interstellar medium (ISM), yet the branching…
