Separating extended disc features from the protoplanet in PDS 70 using VLT/SINFONI
V. Christiaens, S. Casassus, O. Absil +12
Transition discs are prime targets to look for protoplanets and study planet-disc interactions. We present VLT/SINFONI observations of PDS~70, a transition disc with a recently cla…
Exploring DCO as a tracer of thermal inversion in the disk around the Herbig Ae star HD163296
V. N. Salinas, M. R. Hogerheijde, N. M. Murillo +4
We aim to reproduce the DCO emission in the disk around HD163296 using a simple 2D chemical model for the formation of DCO through the cold deuteration channel and a parame…
Characterization of low-mass companion HD 142527 B
V. Christiaens, S. Casassus, O. Absil +10
The circumstellar disk of the Herbig Fe star HD 142527 is host to several remarkable features including a warped inner disk, a 120 au-wide annular gap, a prominent dust trap and se…
DCO, DCN and ND reveal three different deuteration regimes in the disk around the Herbig Ae star HD163296
V. N. Salinas, M. R. Hogerheijde, G. S. Mathews +4
The formation pathways of deuterated species trace different regions of protoplanetary disks and may shed light into their physical structure. We aim to constrain the radial extent…
First detection of gas-phase ammonia in a planet-forming disk
Vachail N. Salinas, Michiel R. Hogerheijde, Edwin A. Bergin +10
Nitrogen chemistry in protoplanetary disks and the freeze-out on dust particles is key to understand the formation of nitrogen bearing species in early solar system analogs. So far…
On the Commonality of 10-30AU Sized Axisymmetric Dust Structures in Protoplanetary Disks
Ke Zhang, Edwin A. Bergin, Geoffrey A. Blake +4
An unsolved problem in step-wise core-accretion planet formation is that rapid radial drift in gas-rich protoplanetary disks should drive mm-/meter-sized particles inward to the ce…
