SO as shock tracer in protoplanetary disks: the AB Aurigae case
A. Dutrey, E. Chapillon, S. Guilloteau +9
{Sulfur Monoxide is known to be a good shock tracer in molecular clouds and protostar environments, but its abundance is difficult to reproduce even using state-of-the-art astroche…
The shadow of the Flying Saucer: A very low temperature for large dust grains
S. Guilloteau, V. Piétu, E. Chapillon +6
Dust determines the temperature structure of protoplanetary disks. However, dust temperature determinations almost invariably rely on a complex modeling of the Spectral Energy Dist…
Faint disks around classical T Tauri stars: small but dense enough to form planets?
V. Piétu, S. Guilloteau, E. di Folco +2
(abridged) Most Class II sources (of nearby star forming regions) are surrounded by disks with weak millimeter continuum emission. These "faint" disks may hold clues to the disk di…
Chemistry in Disks VIII: the CS molecule as an analytic tracer of turbulence in disks
S. Guilloteau, A. Dutrey, V. Wakelam +5
Turbulence is thought to be a key driver of the evolution of protoplanetary disks, regulating the mass accretion process, the transport of angular momentum, and the growth of dust…
A sensitive survey for 13CO, CN, H2CO and SO in the disks of T Tauri and Herbig Ae stars
S. Guilloteau, E. Di Folco, A. Dutrey +3
We use the IRAM 30-m telescope to perform a sensitive search for CN N=2-1 in 42 T Tauri or Herbig Ae systems located mostly in the Taurus-Auriga region. CO J=2-1 is observed…
The long-term millimeter activity of active galactic nuclei
S. Trippe, M. Krips, V. Pietu +8
We analyze the long-term evolution of the fluxes of six active galactic nuclei (AGN) - 0923+392, 3C 111, 3C 273, 3C 345, 3C 454.3, and 3C 84 - in the frequency range 80-267 GHz usi…
A dual-frequency sub-arcsecond study of proto-planetary disks at mm wavelengths: First evidence for radial variations of the dust properties
S. Guilloteau, A. Dutrey, V. Piétu +1
(Abridged) We attempt to characterize the radial distribution of dust in disks around a sample of young stars from an observational point of view, and, when possible, in a model-in…
Chemistry in Disks. III. -- Photochemistry and X-ray driven chemistry probed by the ethynyl radical (CCH) in DM Tau, LkCa 15, and MWC 480
Th. Henning, D. Semenov, St. Guilloteau +7
We studied several representative circumstellar disks surrounding the Herbig Ae star MWC 480 and the T Tauri stars LkCa 15 and DM Tau at (sub-)millimeter wavelengths in lines of CC…
