Quantifying the Impact of the Dust Torque on the Migration of Low-mass Planets
The Astrophysical Journal, 2023 Disk solids are critical in many planet formation processes; however, their effect on planet migration remains largely unexplored. Here we assess this important issue for the first time by building on the systematic measurements of dust torques on an ...

Substructures in Compact Disks of the Taurus Star-forming Region
The Astrophysical Journal, 2023 Observations of substructure in protoplanetary disks have largely been limited to the brightest and largest disks, excluding the abundant population of compact disks, which are likely sites of planet formation.

A Large Double-ring Disk Around the Taurus M Dwarf J04124068+2438157
The Astrophysical Journal, 2023 Planet formation imprints signatures on the physical structures of disks. In this paper, we present high-resolution (∼50 mas, 8 au) Atacama Large Millimeter/submillimeter Array observations of 1.3 mm dust continuum and CO line emission toward the disk ...

Simulating planet migration in globally evolving disks [PDF]
, 2006 Numerical simulations of planet-disk interactions are usually performed with hydro-codes that -- because they consider only an annulus of the disk, over a 2D grid -- can not take into account the global evolution of the disk.

Secular interactions between inclined planets and a gaseous disk [PDF]
, 2001 In a planetary system, a secular particle resonance occurs at a location where the precession rate of a test particle (e.g. an asteroid) matches the frequency of one of the precessional modes of the planetary system.

MAMA: An Algebraic Map for the Secular Dynamics of Planetesimals in Tight Binary Systems [PDF]
, 2013 We present an algebraic map (MAMA) for the dynamical and collisional evolution of a planetesimal swarm orbiting the main star of a tight binary system (TBS).

Excitation of Planetary Obliquities Through Planet-Disk Interactions [PDF]
, 2019 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.

TOI-1859b: A 64 Day Warm Jupiter on an Eccentric and Misaligned Orbit
The Astrophysical Journal Letters, 2023 Warm Jupiters are close-in giant planets with relatively large planet–star separations (i.e., 10 < a / R _⋆ < 100). Given their weak tidal interactions with their host stars, measurements of stellar obliquity may be used to probe the initial obliquity ...

RAPID: A fast, high resolution, flux-conservative algorithm designed for planet-disk interactions [PDF]
, 2008 We describe a newly developed hydrodynamic code for studying accretion disk processes. The numerical method uses a finite volume, nonlinear, Total Variation Diminishing (TVD) scheme to capture shocks and control spurious oscillations.
