The clumpy structure of the chemically active L1157 outflow
Milena Benedettini, Serena Viti, Claudio Codella +5
We present high spatial resolution maps, obtained with the Plateau de Bure Interferometer, of the blue lobe of the L1157 outflow. We observed four lines at 3 mm, namely CH3OH (2_K-…
Molecular line radiative transfer in protoplanetary disks: Monte Carlo simulations versus approximate methods
Ya. Pavlyuchenkov, D. Semenov, Th. Henning +4
We analyze the line radiative transfer in protoplanetary disks using several approximate methods and a well-tested Accelerated Monte Carlo code. A low-mass flaring disk model with…
Probing the structure of protoplanetary disks: a comparative study of DM Tau, LkCa 15 and MWC 480
Vincent Piétu, Anne Dutrey, Stéphane Guilloteau
We report sub-arcsec CO observations of the disks around MWC 480, LkCa 15 and DM Tau, and simultaneous measurements of HCO+ J=1-0. We derive the disk properties by fitting a standa…
