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…
Spatially resolved HCN J=4--3 and CS J=7--6 emission from the disk around HD 142527
G. van der Plas, S. Casassus, F. Menard +4
The disk around HD 142527 attracts a lot of attention, amongst others because of its resolved (sub) mm dust continuum that is concentrated into a horseshoe-shape towards the north…
Spiral arms in the disk of HD 142527 from CO emission lines with ALMA
Valentin Christiaens, Simon Casassus, Sebastian Perez +2
In view of both the size of its gap and the previously reported asymmetries and near-infrared spiral arms, the transition disk of the Herbig Fe star HD 142527 constitutes a remarka…
