The UMIST Database for Astrochemistry 2006
Aims. We present a new version of the UMIST Database for Astrochemistry, the fourth such version to be released to the public. The current version contains some 4573 binary gas-phase reactions, an… Expand
A chemical model for the atmosphere of hot Jupiters
Our purpose is to release a chemical network, and the associated rate coefficients, developed for the temperature and pressure range relevant to hot Jupiters atmospheres. Using this network, we study… Expand
Formation of simple organic molecules in inner T Tauri disks
Aims. We present time dependent chemical models for a dense and warm O-rich gas exposed to a strong, far ultraviolet (FUV) field aimed at exploring the formation of simple organic molecules in the… Expand
Molecular abundances in the inner layers of IRC +10216
Observations towards IRC +10216 of CS, SiO, SiS, NaCl, KCl, AlCl, AlF, and NaCN have been carried out with the IRAM 30-m telescope in the 80-357.5 GHz frequency range. A large number of rotational… Expand
Pseudo 2D chemical model of hot-Jupiter atmospheres: application to HD 209458b and HD 189733b
We have developed a pseudo two-dimensional model of a planetary atmosphere, which takes into account thermochemical kinetics, photochemistry, vertical mixing, and horizontal transport, the latter… Expand
Chemistry of dark clouds: databases, networks, and models.
The state of the art concerning the chemical modeling of dark clouds, the initial step for the formation of stars and disks is assessed. Expand
Laboratory and Astronomical Detection of the Negative Molecular Ion C3N
The negative molecular ion C3N− has been detected at millimeter wavelengths in a low-pressure laboratory discharge, and then with frequencies derived from the laboratory data in the molecular… Expand
Discovery of Phosphaethyne (HCP) in Space: Phosphorus Chemistry in Circumstellar Envelopes
We present the first detection in space of phosphaethyne, the phosphorus analog of HCN. We have observed with the IRAM 30 m telescope four successive rotational transitions of HCP in the AGB star… Expand
Search for anions in molecular sources: C4H - detection in L1527
Based on observations carried out with the IRAM 30 m telescope. IRAM is supported by INSU/CNRS (France), MPG (Germany) and IGN (Spain).-- Accepted for publication in Astronomy & Astrophysics Letters.
