We study the content in S-bearing molecules of protoplanetary disks around low-mass stars. We used the new IRAM 30-m receiver EMIR to perform simultaneous observations of the $1_{10}-1_{01}$ line of H$_2$S at 168.8 GHz and $2_{23}-1_{12}$ line of SO

We study the molecular content and chemistry of a circumstellar disk surrounding the Herbig Ae star AB Aur at (sub-)millimeter wavelengths. Our aim is to reconstruct the chemical history and composition of the AB Aur disk and to compare it with disks

Chemistry in disks I - Deep search for N$_2$H$^+$ in the protoplanetary disks around LkCa 15, MWC 480, and DM Tau

Autor: Dutrey, Anne, Henning, Thomas, Guilloteau, Stephane, Semenov, Dmitry, Pietu, Vincent, Schreyer, Katharina, Bacmann, Aurore, Launhardt, Ralf, Pety, Jerome, Gueth, Frederic

Aims: To constrain the ionization fraction in protoplanetary disks, we present new high-sensitivity interferometric observations of N$_2$H$^+$ in three disks surrounding DM Tau, LkCa 15, and MWC 480. Methods: We used the IRAM PdBI array to observe th

In the course of a comprehensive mm/submm survey of massive star-forming regions, the vicinities of a sample of 47 luminous IRAS sources were closely investigated with SCUBA and IRAM bolometers in order to search for massive protostellar candidates.

We summarize in this poster a long-term study of the chemistry as a powerful tool to constrain the protoplanetary disk physics. Most of the above results were obtained in the frame of the CID (Chemistry In Disks) consortium.
