▪ Abstract Our understanding of the evolution of organic molecules, and their voyage from
molecular clouds to the early solar system and Earth, has changed dramatically …

A systematic analysis of the mixing ratios with respect to H 2 O for eight species (CH 3 OH,
HCN, NH 3, H 2 CO, C 2 H 2, C 2 H 6, CH 4, and CO) measured with high-resolution infrared …

Context. The ESA Rosetta spacecraft (S/C) is tracking comet 67P/Churyumov-Gerasimenko
in close vicinity. This prolonged encounter enables studying the evolution of the volatile …

The composition of cometary ices provides key information on the chemical and physical
properties of the outer solar nebula where comets formed, 4.6 Gy ago. This chapter …

Acetylene, among the multitude of organic molecules discovered in space, plays a distinct
role in the genesis of organic matter. Characterized by its unique balance of stability and …

ABSTRACT A new ro-vibrational line list for the ground electronic state of the main
isotopologue of acetylene, 12C2H2, is computed as part of the ExoMol project. The aCeTY …

Spectra of interstellar CO 2 ice absorption features at a resolving power of λ/Δ λ≈ 1500–
2000 are presented for 14 lines of sight. The observations were made with the Short …

Abstract The VIRTIS (Visual IR Thermal Imaging Spectrometer) experiment has been one of
the most successful experiments built in Europe for Planetary Exploration. VIRTIS …

Ethane, methane, and acetylene were detected in Comets C/1996 B2 Hyakutake and
C/1995 O1 Hale–Bopp. In order to investigate the possibility of condensed-phase synthesis …

Pure methane ices (CH 4) were irradiated at 10 K with energetic electrons to mimic the
energy transfer processes that occur in the track of the trajectories of MeV cosmic-ray …
