Capture and Escape of Planetary Mean-motion Resonances in Turbulent Discs

Yi-Xian Chen, Yinhao Wu, Ya-Ping Li +4

Mean-motion resonances (MMRs) form through convergent disc migration of planet pairs, which may be disrupted by dynamical instabilities after protoplanetary disc (PPD) dispersal. T…

Planet Migration in Windy Discs

Yinhao Wu, Yi-Xian Chen

Accretion of protoplanetary discs (PPDs) could be driven by MHD disc winds rather than turbulent viscosity. With a dynamical prescription for angular momentum transport induced by…

Concurrent Accretion and Migration of Giant Planets in their Natal Disks with Consistent Accretion Torque

Ya-Ping Li, Yi-Xian Chen, Douglas N. C. Lin

Migration commonly occurs during the epoch of planet formation. For emerging gas giant planets, it proceeds concurrently with their growth through the accretion of gas from their n…

The Population of Massive Stars in AGN Disks

Yi-Xian Chen, Douglas N. C. Lin

Gravitational instability in the outskirts of Active Galactic Nuclei (AGN) disks lead to disk fragmentation and formation of super-massive (several 10^2Msun) stars with potentially…

APPLE: An Evolution Code for Modeling Giant Planets

Ankan Sur, Yubo Su, Roberto Tejada Arevalo +2

We introduce APPLE, a novel planetary evolution code designed specifically for the study of giant exoplanet and Jovian planet evolution in the era of Galileo, Juno, and Cassini. Wi…

Dust Accumulation near the Magnetospheric Truncation of Protoplanetary Discs. II. The Effects of Opacity and Thermal Evolution

Rixin Li, Yi-Xian Chen, Douglas N. C. Lin

Dust trapping in the global pressure bump induced by magnetospheric truncation offers a promising formation mechanism for close-in super-Earths/sub-Neptunes. These planets likely f…

Chaotic Type I Migration in Turbulent Discs

Yinhao Wu, Yi-Xian Chen, Douglas N. C. Lin

By performing global hydrodynamical simulations of accretion discs with driven turbulence models, we demonstrate that elevated levels of turbulence induce highly stochastic migrati…

3D Global Simulations of Accretion onto Gap-opening Planets: Implications for Circumplanetary Disc Structures and Accretion Rates

Ya-Ping Li, Yi-Xian Chen, Douglas N. C. Lin

We perform a series of 3D simulations to study the accretion of giant planet embedded in protoplanetary discs (PPDs) over gap-opening timescales. We find that the accretion mass fl…

Jupiter Atmospheric Models and Outer Boundary Conditions for Giant Planet Evolutionary Calculations

Yi-Xian Chen, Adam Burrows, Ankan Sur +1

We present updated atmospheric tables suitable for calculating the post-formation evolution and cooling of Jupiter and Jupiter-like exoplanets. These tables are generated using a 1…

Distinguishing Magnetized Disc Winds from Turbulent Viscosity through Substructure Morphology in Planet-forming Discs

Yinhao Wu, Yi-Xian Chen, Haochang Jiang +5

The traditional paradigm of viscosity-dominated evolution of protoplanetary discs has been recently challenged by magnetized disc winds. However, distinguishing wind-driven and tur…

Chaotic Gas Accretion by Black Holes Embedded in AGN Discs as Cause of Low-spin Signatures in Gravitational Wave Events

Yi-Xian Chen, Douglas N. C. Lin

Accretion discs around super-massive black holes (SMBH) not only power active galactic nuclei (AGNs), but also host single and binary embedded stellar-mass black holes (EBHs) that…

Turbulent Transport of Dust Particles in Protostellar Disks: The Effect of Upstream Diffusion

Tingtao Zhou, Hongping Deng, Yi-Xian Chen +1

We study the long-term radial transport of micron to mm-size grain in protostellar disks (PSDs) based on diffusion and viscosity coefficients measured from 3D global stratified-dis…

Prograde and Retrograde Gas Flow around Disk-embedded Companions: Dependence on Eccentricity, Mass and Disk Properties

Yi-Xian Chen, Avery Bailey, James M. Stone +1

We apply 3D hydrodynamical simulations to study the rotational aspect of gas flow patterns around eccentric companions embedded in an accretion disk around its primary host. We sam…

Dust Accumulation near the Magnetospheric Truncation of Protoplanetary Discs around T Tauri Stars

Rixin Li, Yi-Xian Chen, Douglas N. C. Lin

The prevalence of short-period super-Earths that are independent of host metallicity challenges the theoretical construction of their origin. We propose that dust trapping in the g…
