Description Spitzer NIR observations revealed the presence of warm C2H2 and HCN with large gas phase abundances in the disk around GV Tau N. The emission of these molecules has been interpreted as originated in the disk at R<50 AU, i.e., in the planet formation zone. Recent observations by our team of the HCN 1-0 and 3-2 lines using the IRAM 30m telescope and the Plateau de Bure Interferometer give further support to this interpretation. We propose to complete the mm and NIR observations by observing the HCN 7-6, 11-6 and 13-12 lines with the instrument HIFI on board Herschel. These detections will allow us to carry out a complete study of the HCN excitation, and to estimate the physical conditions (gas temperature and density), the radius and the kinematics of the emitting region. In addition, we will observe key CO and H2O lines in order to determine the amount of warm gas and derive the HCN and H2O abundance in the inner region of this young disk. To determine the physical conditions and chemical composition of this inner disk gas is the key to understand the evolution of the volatile material that becomes incorporated into the planet-forming regions.

Mission Description Herschel was launched on 14 May 2009! It is the fourth 'cornerstone' mission in the ESA science programme. With a 3.5 m Cassegrain telescope it is the largest space telescope ever launched. It is performing photometry and spectroscopy in approximately the 55-671 ┬Ám range, bridging the gap between earlier infrared space missions and groundbased facilities.
