Atomic line radiative transfer with MCFOST I. Code description and benchmarking
B. Tessore, C. Pinte, J. Bouvier +1
Aims. We present MCFOST-art, a new non-local thermodynamic equilibrium radiative transfer solver for multilevel atomic systems. The code is embedded in the 3D radiative transfer co…
FAUST I. The hot corino at the heart of the prototypical Class I protostar L1551 IRS5
E. Bianchi, C. J. Chandler, C. Ceccarelli +63
The study of hot corinos in Solar-like protostars has been so far mostly limited to the Class 0 phase, hampering our understanding of their origin and evolution. In addition, recen…
ALMA study of the HD 100453 AB system and the tidal interaction of the companion with the disk
G. van der Plas, F. Ménard, J. -F. Gonzalez +6
Context: The complex system HD 100453 AB with a ring-like circumprimary disk and two spiral arms, one of which is pointing to the secondary, is a good laboratory to test spiral for…
Radial decoupling of small and large dust grains in the transitional disk RX J1615.3-3255
Robin Kooistra, Inga Kamp, Misato Fukagawa +56
We present H-band (1.6 μm) scattered light observations of the transitional disk RX J1615.3-3255, located in the ~1 Myr old Lupus association. From a polarized intensity image, tak…
A cavity and further radial substructures in the disk around HD~97048
G. van der Plas, C. M. Wright, F. Ménard +9
Context: Gaps, cavities and rings in circumstellar disks are signposts of disk evolution and planet-disk interactions. We follow the recent suggestion that Herbig Ae/Be disks with…
Gas inside the 97 au cavity around the transition disk Sz\,91
H. Canovas, M. R. Schreiber, C. Cáceres +9
We present ALMA (Cycle 0) band-6 and band-3 observations of the transition disk Sz\,91. The disk inclination and position angle are determined to be $i=49.5\degr\pm3.5\degr$ and $\…
A CO survey in planet-forming disks: characterizing the gas content in the epoch of planet formation
A. S. Hales, I. De Gregorio-Monsalvo, B. Montesinos +13
We carried out a 12CO(3-2) survey of 52 southern stars with a wide range of IR excesses (LIR/L*) using the single dish telescopes APEX and ASTE. The main aims were (1) to character…
Constraining the structure of the transition disk HD 135344B (SAO 206462) by simultaneous modeling of multiwavelength gas and dust observations
A. Carmona, C. Pinte, W. F. Thi +14
HD 135344B is an accreting (pre-) transition disk that displays the emission of warm CO extending tens of AU inside its 30 AU dust cavity. We used the dust radiative transfer code…
Gas and dust in the Beta Pictoris Moving Group as seen by the Herschel Space Observatory
P. Riviere-Marichalar, D. Barrado, B. Montesinos +11
Context. Debris discs are thought to be formed through the collisional grinding of planetesimals, and can be considered as the outcome of planet formation. Understanding the proper…
[OI] disk emission in the Taurus star forming region
G. Aresu, I. Kamp, R. Meijerink +8
The structure of protoplanetary disks is thought to be linked to the temperature and chemistry of their dust and gas. Whether the disk is flat or flaring depends on the amount of r…
Unveiling the gas and dust disk structure in HD 163296 using ALMA observations
I. de Gregorio-Monsalvo, F. Ménard, W. Dent +20
Aims: The aim of this work is to study the structure of the protoplanetary disk surrounding the Herbig Ae star HD 163296. Methods: We have used high-resolution and high-sensitivity…
Gas and dust in the TW Hydrae Association as seen by the Herschel Space Observatory
P. Riviere-Marichalar, C. Pinte, D. Barrado +15
Context. Circumstellar discs are the places where planets form, therefore knowledge of their evolution is crucial for our understanding of planet formation. The Herschel Space Obse…
HD 172555: detection of 63 microns [OI] emission in a debris disc
P. Riviere-Marichalar, D. Barrado, J. -C. Augereau +14
Context. HD 172555 is a young A7 star belonging to the Beta Pictoris Moving Group that harbours a debris disc. The Spitzer IRS spectrum of the source showed mid-IR features such as…
The dynamically disrupted gap in HD 142527
S. Casassus, S. Perez M., A. Jordán +5
The vestiges of planet formation have been observed in debris disks harboring young and massive gaseous giants. The process of giant planet formation is terminated by the dissipati…
Gas modelling in the disc of HD 163296
I. Tilling, P. Woitke, G. Meeus +19
We present detailed model fits to observations of the disc around the Herbig Ae star HD 163296. This well-studied object has an age of ~ 4 Myr, with evidence of a circumstellar dis…
