Shadows Cast by a Warp in the HD 142527 Protoplanetary Disk
(The American Astronomical Society, 2015-01-10)
Detailed observations of gaps in protoplanetary disks have revealed structures that drive current research on
circumstellar disks. One such feature is the two intensity nulls seen along the outer disk of the HD 142527 ...
Horseshoe drag in three-dimensional globally isothermal disks
(IOP Publishing, 2016-01)
We study the horseshoe dynamics of a low-mass planet in a three-dimensional, globally isothermal, inviscid disk. We find, as reported in previous work, that the boundaries of the horseshoe region (separatrix sheets) have ...
Probing the final stages of protoplanetary disk evolution with ALMA
(EDP Sciences, 2015)
Context. The evolution of a circumstellar disk from its gas-rich protoplanetary stage to its gas-poor debris stage is not understood well. It is apparent that disk clearing progresses from the inside-out on a short time ...
The accumulation and trapping of grains at planet gaps: Effects of grain growth and fragmentation
(Elsevier, 2015)
We model the dust evolution in protoplanetary disks with full 3D, Smoothed Particle Hydrodynamics (SPH), two-phase (gas+ dust) hydrodynamical simulations. The gas+ dust dynamics, where aerodynamic drag leads to the vertical ...
Dynamical evidence for an early giant planet instability
(2020-03-15)
The dynamical structure of the Solar System can be explained by a period of orbital instability experienced by the giant planets. While a late instability was originally proposed to explain the Late Heavy Bombardment, ...
Dust trapping around Lagrangian points in protoplanetary disks
(EDP Sciences, 2020-10)
Trojans are defined as objects that share the orbit of a planet at the stable Lagrangian points L4 and L5. In the Solar System, these bodies show a broad size distribution ranging from micrometer (μm) to centimeter (cm) ...
The dynamically disrupted GAP in HD 142527
(IOP PUBLISHING LTD, 2012-08-01)
The vestiges of planet formation have been observed in debris disks harboring young and massive gaseous giants. The process of giant planet formation is terminated by the dissipation of gas in the protoplanetary disk. The ...
