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…
Probing the Final Stages of Protoplanetary Disk Evolution with ALMA
A. Hardy, C. Caceres, M. R. Schreiber +5
The evolution of a circumstellar disk from its gas-rich protoplanetary stage to its gas-poor debris stage is not understood well. It is apparent that disk clearing progresses from…
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 $\…
CO gas inside the protoplanetary disk cavity in HD 142527: disk structure from ALMA
Sebastian Perez, S. Casassus, F. Ménard +6
Inner cavities and annular gaps in circumstellar disks are possible signposts of giant planet formation. The young star HD 142527 hosts a massive protoplanetary disk with a large c…
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…
