A tunnel and a traffic jam: How transition disks maintain a detectable warm dust component despite the presence of a large planet-carved gap
Paola Pinilla, Lucia Klarmann, Tilman Birnstiel +3
We combined hydrodynamical simulations of planet-disk interactions with dust evolution models that include coagulation and fragmentation of dust grains over a large range of radii…
Variability and dust filtration in the transition disk J160421.7-213028 observed in optical scattered light
P. Pinilla, J. de Boer, M. Benisty +9
Context. Some of transition disks show asymmetric structures in thermal sub-millimetre emission and optical scattered light. These structures can be the result of planet(s) or comp…
Dust Evolution Can Produce Scattered Light Gaps in Protoplanetary Disks
Tilman Birnstiel, Sean M. Andrews, Paola Pinilla +1
Recent imaging of protoplanetary disks with high resolution and contrast have revealed a striking variety of substructure. Of particular interest are cases where near-infrared scat…
Testing particle trapping in transition disks with ALMA
P. Pinilla, N. van der Marel, L. M. Pérez +6
We present new Atacama Large Millimeter/submillimeter Array (ALMA) continuum observations at 336GHz of two transition disks, SR21 and HD135344B. In combination with previous ALMA o…
A concentration of centimeter-sized grains in the Oph IRS 48 dust trap
Nienke van der Marel, Paola Pinilla, John Tobin +4
Azimuthally asymmetric dust distributions observed with ALMA in transition disks have been interpreted as dust traps. We present VLA Ka band (34 GHz or 0.9 cm) and ALMA Cycle 2 Ban…
Sequential planet formation in the HD 100546 protoplanetary disk?
P. Pinilla, T. Birnstiel, C. Walsh
Context. The disk around the Herbig Ae star, HD 100546, shows structures that suggest the presence of two companions in the disk at and AU. The outer companion se…
