A colorful view of planet formation:A multi-wavelength study of planet-disk interactions [PDF]
, 2021 The broad variety of planets and planetary systems discovered in the last couple of decades around other stars has taught us that these can be, and more often than not tend to be, very different from our own.

Planet–Disk Interaction in Disks with Cooling: Basic Theory [PDF]
The Astrophysical Journal, 2020 Abstract Gravitational coupling between young planets and their parent disks is often explored using numerical simulations, which typically treat the disk thermodynamics in a highly simplified manner. In particular, many studies adopt the locally isothermal approximation, in which the disk temperature is a fixed function of the ...

Constraining the gas distribution in the PDS 70 disk as a method to assess the effect of planet-disk interactions [PDF]
, 2023 Embedded planets are potentially the cause of substructures like gaps and cavities observed in several protoplanetary disks. Thus, the substructures observed in the continuum and in line emission encode information about the presence of planets in the ...

, 2022 Planet-disk interactions, where an embedded massive body interacts gravitationally with the protoplanetary disk it was formed in, can play an important role in reshaping both the disk and the orbit of the planet. Spiral density waves are launched into the disk by the planet, which, if they are strong enough, can lead to the formation of a gap.

Planet-Disk Interaction revisited [PDF]
EPJ Web of Conferences, 2013 We present results on our investigations of planet–disk interaction in protoplanetary disks. For the hydrodynamic simulations we use a second order semi–discrete total variation diminishing (TVD) scheme for systems of hyperbolic conservation laws on curvilinear grids.

Excitation of Planetary Obliquities through Planet–Disk Interactions [PDF]
The Astrophysical Journal, 2019 Abstract The tilt of a planet’s spin axis off its orbital axis (“obliquity”) is a basic physical characteristic that plays a central role in determining the planet’s global circulation and energy redistribution. Moreover, recent studies have also highlighted the importance of obliquities in sculpting not only the physical features of ...

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

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 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,
