Pebble-driven migration of low-mass planets in the 2D regime of pebble accretion

O Chrenko, RO Chametla, FS Masset… - Astronomy & …, 2024 - aanda.org
Context. Pebbles drifting past a disk-embedded low-mass planet develop asymmetries in
their distribution and exert a substantial gravitational torque on the planet, thus modifying its …

Dust rings trap protoplanets on eccentric orbits and get consumed by them

DA Velasco-Romero, FS Masset… - Monthly Notices of …, 2024 - academic.oup.com
We study the orbital evolution and mass growth of protoplanets with masses M in the vicinity
of a dusty ring, using three-dimensional numerical simulations with a two-fluid model and …

Accreting luminous low-mass planets escape from migration traps at pressure bumps

O Chrenko, RO Chametla - Monthly Notices of the Royal …, 2023 - academic.oup.com
We investigate the migration of Mars-to super-Earth-sized planets in the vicinity of a
pressure bump in a 3D radiative protoplanetary disc while accounting for the effect of …

Growth and evolution of low-mass planets in pressure bumps

A Pierens, SN Raymond - Astronomy & Astrophysics, 2024 - aanda.org
Observations of protoplanetary disks have revealed dust rings that are likely due to the
presence of pressure bumps in the disk. Because these structures tend to trap drifting …

A simple time-dependent method for calculating spirals: applications to eccentric planets in protoplanetary discs

Z Zhu, RM Zhang - Monthly Notices of the Royal Astronomical …, 2022 - academic.oup.com
Spirals in protoplanetary discs have been used to locate the potential planet in discs. Since
only the spiral shape from a circularly orbiting perturber is known, most previous works …

Apsidal alignment and anti-alignment of planets in mean-motion resonance: disc-driven migration and eccentricity driving

JT Laune, L Rodet, D Lai - Monthly Notices of the Royal …, 2022 - academic.oup.com
Planets migrating in their natal discs can be captured into mean-motion resonance (MMR),
in which the planets' periods are related by integer ratios. Recent observations indicate that …

Resonant Excitation of Planetary Eccentricity due to a Dispersing Eccentric Protoplanetary Disk: A New Mechanism of Generating Large Planetary Eccentricities

J Li, D Lai - The Astrophysical Journal, 2023 - iopscience.iop.org
We present a new mechanism of generating large planetary eccentricities. This mechanism
applies to planets within the inner cavities of their companion protoplanetary disks. A …

On the interaction of pebble accreting embryos with the gaseous disc: importance of thermal forces

S Cornejo, FS Masset… - Monthly Notices of the …, 2023 - academic.oup.com
ABSTRACT A planetary embryo embedded in a gaseous disc can grow by pebble accretion
while subjected to a gravitational force from the disc that changes its orbital elements …

How the planetary eccentricity influences the pebble isolation mass

RO Chametla, FS Masset, C Baruteau… - Monthly Notices of the …, 2022 - academic.oup.com
We investigate the pebble isolation mass (PIM) for a planet on a fixed eccentric orbit in its
protoplanetary disc by conducting a set of two-dimensional (2D) hydrodynamical …

On the evolution of pebble-accreting planets in evolving protoplanetary discs

A Pierens - Monthly Notices of the Royal Astronomical Society, 2023 - academic.oup.com
We examine the migration of luminous low-mass cores in laminar protoplanetary discs
where accretion occurs mainly because of disc winds and where the planet luminosity is …
