On the number of particles in N-body simulations of planet–disk interaction [PDF]
Planetary and Space Science, 2007 Abstract In this paper we present a new mixed-variables symplectic tree code for planetesimal dynamics, which allows to use a very large number of particles in numerical simulations of planet–disk interaction. Furthermore, we discuss how a wrong election of the number of particles to model a planetesimal disk, in order to carry out realistic ...

The Astrophysical Journal Letters, 2023 Planets form in dusty, gas-rich disks around young stars, while at the same time, the planet formation process alters the physical and chemical structure of the disk itself. Embedded planets will locally heat the disk and sublimate volatile-rich ices, or

Dynamics of Colombo’s Top: Generating Exoplanet Obliquities from Planet–Disk Interactions [PDF]
The Astrophysical Journal, 2020 Abstract Large planetary spin–orbit misalignments (obliquities) may strongly influence atmospheric circulation and tidal heating in a planet. A promising avenue to generate obliquities is via spin–orbit resonances, where the spin and orbital precession frequencies of a planet cross each other as the system evolves in time.

Planet–disk interaction in VSI-active disks
, 2022 The vertical shear instability (VSI) is a popular mechanism that has been proposed to explain accretion in protoplanetary disks, and could be observable in the near future. With high-resolution numerical hydrodynamics simulations, we model the behavior of the VSI in protoplanetary disks and measure its accretion and mixing capabilities with and without

The Effect of Convective Overstability on Planet Disk Interactions [PDF]
Proceedings of the International Astronomical Union, 2015 AbstractWe run global two dimensional hydrodynamical simulations, using the PLUTO code and the planet-disk model of Uribe et al. 2011, to investigate the effect of the convective overstability (CO) on planet-disk interactions. First, we study the long-term evolution of planet-induced vortices. We found that the CO leads to smoother planetary gap edges,

RODEO: a new method for planet-disk interaction [PDF]
Astronomy & Astrophysics, 2006 In this paper we describe a new method for studying the hydrodynamical problem of a planet embedded in a gaseous disk. We use a finite volume method with an approximate Riemann solver (the Roe solver), together with a special way to integrate the source terms.

Kinematic signatures of planet-disk interactions in VSI-turbulent protoplanetary disks
Astronomy & Astrophysics, 2023 Context. Planets are thought to form inside weakly ionized regions of protoplanetary disks, where turbulence creates ideal conditions for solid growth. However, the nature of this turbulence is still uncertain. In this zone, vertical shear instability (VSI) can operate, inducing a low level of gas turbulence and large-scale motions. Resolving kinematic

MODELING DUST EMISSION OF HL TAU DISK BASED ON PLANET–DISK INTERACTIONS [PDF]
The Astrophysical Journal, 2016 ABSTRACT We use extensive global two-dimensional hydrodynamic disk gas+dust simulations with embedded planets, coupled with three-dimensional radiative transfer calculations, to model the dust ring and gap structures in the HL Tau protoplanetary disk observed with the Atacama Large Millimeter/Submillimeter Array (ALMA).
