On the diversity of asymmetries in gapped protoplanetary disks
Protoplanetary disks with large inner dust cavities are thought to host massive planetary or
substellar companions. These disks show asymmetries and rings in the millimeter …

Impact of a plasma on the relaxation of black holes
E Cannizzaro, TFM Spieksma, V Cardoso, T Ikeda - Physical Review D, 2024 - APS
Our Universe is permeated with interstellar plasma, which prevents propagation of low-
frequency electromagnetic waves. Here, we show that two dramatic consequences arise out …

Homogeneous analysis of the dust morphology of transition disks observed with ALMA: investigating dust trapping and the origin of the cavities
We analyze the dust morphology of 29 transition disks (TDs) observed with Atacama Large
(sub-) Millimeter Array (ALMA) at (sub-) millimeter emission. We perform the analysis in the …

Spiral arms in disks: planets or gravitational instability?
R Dong, JR Najita, S Brittain - The Astrophysical Journal, 2018 - iopscience.iop.org
Spiral arm structures seen in scattered-light observations of protoplanetary disks can
potentially serve as signposts of planetary companions. They can also lend unique insights …

ISPY: NACO Imaging Survey for Planets around Young stars-The demographics of forming planets embedded in protoplanetary disks
Context. Planet formation is a frequent process, but little observational constraints exist
about the mechanisms involved, especially for giant planets at large separation. The NaCo …

Variable Outer Disk Shadowing around the Dipper Star RXJ1604. 3–2130
P Pinilla, M Benisty, J de Boer, CF Manara… - The Astrophysical …, 2018 - iopscience.iop.org
Low brightness dips have recently been observed in images of protoplanetary disks, and
they are believed to be shadows by the inner disk. We present VLT/SPHERE polarimetric …

The circumstellar disk HD 169142: gas, dust, and planets acting in concert?
A Pohl, M Benisty, P Pinilla, C Ginski… - The Astrophysical …, 2017 - iopscience.iop.org
HD 169142 is an excellent target for investigating signs of planet–disk interaction due to
previous evidence of gap structures. We perform J-band (∼ 1.2 μm) polarized intensity …

Deep imaging search for planets forming in the TW Hya protoplanetary disk with the Keck/NIRC2 vortex coronagraph
Distinct gap features in the nearest protoplanetary disk, TW Hya (distance of 59.5±0.9 pc),
may be signposts of ongoing planet formation. We performed long-exposure thermal …
