KIDA: A KInetic Database for Astrochemistry. Abstract:
Database for Astrochemistry
KIDA (for KInetic Database for Astrochemistry) is a project initiated by different communities in order to 1) improve the interaction between astrochemists and physico-chemists and 2) simplify the work of modeling the chemistry of astrophysical environments. Here astrophysical environments stand for the interstellar medium and planetary atmospheres. Both types of environments use similar chemical networks and the physico-chemists who work on the determination of reaction rate coefficients for both types of environment are the same.
Who is involved in KIDA?
Although the database is physically located at the Observatoire Aquitain des Sciences de l’Univers in Bordeaux (France), this is an international project. Anyone in these fields of research can be involved in this project by submitting data to KIDA. We are also always looking for experts in kinetic data to work on recommendations for astrophysicists. If you are interested, please contact us by email: [email protected]
What is the goal of KIDA?
KIDA (for KInetic Database for Astrochemistry) was built with the aim of improving the exchange between two communities: astrophysicists and physico-chemists who determine the reaction rate coefficients. KIDA is a database, which will contain all the kinetic data that can be of interest for the chemical modeling of the interstellar medium and planetary atmospheres. In addition of containing information about the data (references, details about the methods to obtain the data, range of temperature etc), the interface of the database allows physicists and chemists to upload themselves their data. In order to provide help the non-chemists, a group of experts will give expertise on the quality of the data. Astrophysicists can also publicly store their models (lists of reactions) to allow the reproducibility of published works.
Review process of data by KIDA experts
What do we do with kinetic data in astrophysics?
To study the chemical composition and evolution of an astrophysical object or a planetary atmosphere, astrophysicistsuse chemical models in which the chemistry is driven by hundreds to thousands of reactions. The resulting species abundances can be very sensitive to the reaction rate coefficients used in these models and their uncertainties. The data in KIDA have to be valid on a large range of temperature and pressure to be used in a variety of objects (interstellar medium, protoplanetary disks, shocks, planetary and exo-planetary atmospheres etc).

Submitting data to KIDA
Fig. on the top: Context of KIDA: The improvement of the data stored in KIDA will be done by the identification of important reactions for specific objects and by the review of a group of experts on these reactions. Interactions of KIDA with other projects are described above.
