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 ...

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 ...

The Influence of Cold Jupiters in the Formation of Close-in Planets. I. Planetesimal Transport
The Astrophysical Journal, 2023 The formation of a cold Jupiter (CJ) is expected to quench the influx of pebbles and the migration of cores interior to its orbit, thus limiting the efficiency of rocky planet formation either by pebble accretion and/or orbital migration.

The Astrophysical Journal Letters, 2023 High-eccentricity migration is a likely formation mechanism for many observed hot Jupiters, particularly those with a large misalignment between the stellar spin axis and orbital angular momentum axis of the planet.

Statistical Distributions of Plasma Density and Pressure in the Jovian Plasma Sheet
The Astrophysical JournalThe Jovian plasma sheet is a key region of the Jovian magnetosphere populated by a mix of warm and hot plasma. It is the main channel for radial transport of mass and energy in the Jovian magnetosphere and provides a favorable environment for magnetic ...

Callisto’s Nonresonant Orbit as an Outcome of Circum-Jovian Disk Substructure
The Astrophysical JournalThe Galilean moons of Io, Europa, and Ganymede exhibit a 4:2:1 commensurability in their mean motions, a configuration known as the Laplace resonance. The prevailing view for the origin of this three-body resonance involves the convergent migration of ...

The Astrophysical Journal, 2023 Giant planets embedded in protoplanetary disks (PPDs) can create annulus density gaps around their orbits in the type-II regime, potentially responsible for the ubiquity of annular substructures observed in PPDs.
