TL;DR: The detection of a dust trap in the disk around the star Oph IRS 48 is reported using observations from the Atacama Large Millimeter/submillimeter Array (ALMA) and the difference in distribution of big grains versus small grains/gas can be modeled with a vortex-shaped dust trap triggered by a companion.

TL;DR: In this article, the authors detect a point source within the gap of the transition disk at about 195 mas (~22 au) projected separation and detect a signal from an inner disk component.

TL;DR: In this paper, the presence of a large planet in a disk influences the growth and radial distribution of dust grains, and how observable properties are linked to the mass of the planet, and they combined two-dimensional hydrodynamical disk simulations of disk-planet interactions with state-of-the-art coagulation/fragmentation models to simulate the evolution of dust in a transition disk, which has a gap created by a massive planet.

TL;DR: In this article, the authors use coagulation/fragmentation and disk-structure models to simulate the evolution of dust in a bumpy surface density profile, which they mimic with a sinusoidal disturbance.

TL;DR: In this article, the authors identify the most frequently revealed substructure in ALMA dust observations of protoplanetary disks, and measure their properties to investigate how they form, including axisymmetric rings and gaps.
