Chemistry in Disks. II. -- Poor molecular content of the AB Aur disk
Katharina Schreyer, Stéphane Guilloteau, Dmitry Semenov +9
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 h…
HNCO enhancement by shocks in the L1157 molecular outflow
Nemesio Rodriguez-Fernandez, Mario Tafalla, Frederic Gueth +1
The isocyanic acid (HNCO) presents an extended distribution in the centers of the Milky Way and the spiral galaxy IC342. Based on the morphology of the emission and the HNCO abunda…
CID: Chemistry in disks VI.sulfur-bearing molecules in the protoplanetary disks surrounding LkCa15, MWC480, DM Tau, and GO Tau
Anne Dutrey, Valentine Wakelam, Yann Boehler +9
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_{1…
The HH 212 interstellar laboratory: astrochemistry as a tool to reveal protostellar disks on Solar System scales around a rising Sun
Claudio Codella, Cecilia Ceccarelli, Chin-Fei Lee +8
The investigation of star forming regions have enormously benefited from the recent advent of the ALMA interferometer. More specifically, the unprecedented combination of high-sens…
The Formation Conditions of the Wide Binary Class 0 Protostars within BHR 71
John Tobin, Tyler Bourke, Stacy Mader +7
We present a characterization of the binary protostar system that is forming within a dense core in the isolated dark cloud BHR71. The pair of protostars, IRS1 and IRS2, are both i…
Circumbinary Ring, Circumstellar disks and accretion in the binary system UY Aurigae
Ya-Wen Tang, Anne Dutrey, Stephane Guilloteau +8
Recent exo-planetary surveys reveal that planets can orbit and survive around binary stars. This suggests that some fraction of young binary systems which possess massive circumbin…
