A KINETIC DATABASE FOR ASTROCHEMISTRY (KIDA)

Abstract

We present a novel chemical database for gas-phase astrochemistry. Named the KInetic Database for Astrochemistry
\n(KIDA), this database consists of gas-phase reactions with rate coefficients and uncertainties that will be vetted
\nto the greatest extent possible. Submissions of measured and calculated rate coefficients are welcome, and will
\nbe studied by experts before inclusion into the database. Besides providing kinetic information for the interstellar
\nmedium, KIDA is planned to contain such data for planetary atmospheres and for circumstellar envelopes. Each
\nyear, a subset of the reactions in the database (kida.uva) will be provided as a network for the simulation of the
\nchemistry of dense interstellar clouds with temperatures between 10 K and 300 K. We also provide a code, named
\nNahoon, to study the time-dependent gas-phase chemistry of zero-dimensional and one-dimensional interstellar
\nsources.
