"The Chemistry in Disks" (CID) Project

CID collaboration is an international consortium among the Max Planck Institute for Astronomy (Heidelberg, Germany), Bordeaux Observatory (Bordeaux, France), Institut de Radioastronomie Millimétrique (Grenoble, France), SETI Institute (Mountain View, USA), Institute of Astronomy and Astrophysics (Taiwan, China), Jena Observatory (Jena, Germany), University of Virginia (Charlottesville, USA), and Konkoly Observatory (Budapest, Hungary). CID project is aimed at studying protoplanetary disks around young stars in dust continuum emission and molecular lines with the most sensitive single-dish antennas and interferometers, including the IRAM 30-m, Plateau de Bure/NOEMA, and Atacama Large Millimeter Array (ALMA) facilities. After careful reduction, the data are analyzed in the Fourier plane iteratively, using an advanced Markov Chain Monte Carlo fitting programme "DISKFIT". The observationally-derived parameters include disk physical (temperature, density, kinematics) and chemical structure (location of molecules, column densities). These values are further used in more sophisticated time-dependent, gas-grain chemical models "ALCHEMIC" and "NAHOON", and details of chemical processes at the verge of planet formation are unraveled. The predictions from the models and older observational data are further utilized to guide, optimize and prepare future observations, e.g., using the CASA ALMA Simulator.
