Ro-vibrational Spectroscopy of CI Tau -- Evidence of a Multi-Component Eccentric Disk Induced by a Planet
Janus Kozdon, Sean Brittain, Jeffrey Fung +5
CI Tau is currently the only T Tauri star with an inner protoplanetary disk that hosts a planet, CI Tau b, that has been detected by a radial velocity survey. This provides the uni…
The maximum accretion rate of a protoplanet: how fast can runaway be?
Nick Choksi, Eugene Chiang, Jeffrey Fung +1
The hunt is on for dozens of protoplanets hypothesised to reside in protoplanetary discs with imaged gaps. How bright these planets are, and what they will grow to become, depend o…
Planet-Disk Interactions
Sijme-Jan Paardekooper, Ruobing Dong, Paul Duffell +4
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 d…
Dust Dynamics in Transitional Disks: Clumping and Disk Recession
Jiaqing Bi, Jeffrey Fung
The role of radiation pressure in dust migration and the opening of inner cavities in transitional disks is revisited in this paper. Dust dynamics including radiation pressure is o…
Cooling-Induced Vortex Decay in Keplerian Disks
Jeffrey Fung, Tomohiro Ono
Vortices are readily produced by hydrodynamical instabilities, such as the Rossby wave instability, in protoplanetary disks. However, large-scale asymmetries indicative of dust-tra…
The Three Dimensional Flow Field Around Planets on Eccentric Orbits
Avery Bailey, Jim Stone, Jeffrey Fung
We investigate the properties of the hydrodynamic flow around eccentric protoplanets and compare them with the often assumed case of a circular orbit. To this end, we perform a set…
Visualizing the Kinematics of Planet Formation
Disk Dynamics Collaboration, Philip J. Armitage, Jaehan Bae +23
A stunning range of substructures in the dust of protoplanetary disks is routinely observed across a range of wavelengths. These gaps, rings and spirals are highly indicative of a…
A Staggered Semi-Analytic Method for Simulating Dust Grains Subject to Gas Drag
Jeffrey Fung, Dhruv Muley
Numerical simulations of dust-gas dynamics are one of the fundamental tools in astrophysical research, such as the study of star and planet formation. It is common to find tightly…
Circumplanetary Disk Dynamics in the Isothermal and Adiabatic Limits
Jeffrey Fung, Zhaohuan Zhu, Eugene Chiang
Circumplanetary disks (CPDs) may be essential to the formation of planets, regulating their spin and accretion evolution. We perform a series of 3D hydrodynamics simulations in bot…
PDS 70: A transition disk sculpted by a single planet
Dhruv Muley, Jeffrey Fung, Nienke van der Marel
The wide, deep cavities of transition disks are often believed to have been hollowed out by nascent planetary systems. PDS 70, a Myr old transition disk system in which a…
Observational Signatures of Planets in Protoplanetary Disks: Planet-Induced Line Broadening in Gaps
Ruobing Dong, Sheng-yuan Liu, Jeffrey Fung
Protoplanets can produce structures in protoplanetary disks via gravitational disk-planet interactions. Once detected, such structures serve as signposts of planet formation. Here…
The Eccentric Cavity, Triple Rings, Two-Armed Spirals, and Double Clumps of the MWC 758 Disk
Ruobing Dong, Sheng-yuan Liu, Josh Eisner +15
Spatially resolved structures in protoplanetary disks hint at unseen planets. Previous imaging observations of the transitional disk around MWC 758 revealed an inner cavity, a ring…
Subaru/HiCIAO imaging of LkH 330 - multi-band detection of the gap and spiral-like structures
Taichi Uyama, Jun Hashimoto, Takayuki Muto +56
We present - and -bands observations of the LkH 330 disk with a multi-band detection of the large gap and spiral-like structures. The morphology of the outer disk…
Inner Super-Earths, Outer Gas Giants: How Pebble Isolation and Migration Feedback Keep Jupiters Cold
Jeffrey Fung, Eve Lee
The majority of gas giants (planets of masses ) are found to reside at distances beyond au from their host stars. Within 1 au, the planetary populatio…
The Orbit of the Companion to HD 100453A: Binary-Driven Spiral Arms in a Protoplanetary Disk
Kevin Wagner, Ruobing Dong, Patrick Sheehan +9
HD 100453AB is a 10+/-2 Myr old binary whose protoplanetary disk was recently revealed to host a global two-armed spiral structure. Given the relatively small projected separation…
Stellar Winds and Dust Avalanches in the AU Mic Debris Disk
Eugene Chiang, Jeffrey Fung
We explain the fast-moving, ripple-like features in the edge-on debris disk orbiting the young M dwarf AU Mic. The bright features are clouds of sub-micron dust repelled by the hos…
Complex Spiral Structure in the HD 100546 Transitional Disk as Revealed by GPI and MagAO
Katherine B. Follette, Julien Rameau, Ruobing Dong +53
We present optical and near-infrared high contrast images of the transitional disk HD 100546 taken with the Magellan Adaptive Optics system (MagAO) and the Gemini Planet Imager (GP…
Save the Planet, Feed the Star: How Super-Earths Survive Migration and Drive Disk Accretion
Jeffrey Fung, Eugene Chiang
Two longstanding problems in planet formation include (1) understanding how planets survive migration, and (2) articulating the process by which protoplanetary disks disperse---and…
What is the Mass of a Gap-Opening Planet?
Ruobing Dong, Jeffrey Fung
High contrast imaging instruments such as GPI and SPHERE are discovering gap structures in protoplanetary disks at an ever faster pace. Some of these gaps may be opened by planets…
How Bright are Planet-Induced Spiral Arms in Scattered Light?
Ruobing Dong, Jeffrey Fung
Recently, high angular resolution imaging instruments such as SPHERE and GPI have discovered many spiral-arm-like features in near-infrared scattered light images of protoplanetary…
Planetary Torque in 3D Isentropic Disks
Jeffrey Fung, Frederic Masset, Elena Lega +1
Planet migration is inherently a three-dimensional (3D) problem, because Earth-size planetary cores are deeply embedded in protoplanetary disks. Simulations of these 3D disks remai…
Gap Opening in 3D: Single Planet Gaps
Jeffrey Fung, Eugene Chiang
Giant planets can clear deep gaps when embedded in 2D (razor-thin) viscous circumstellar disks. We show by direct simulation that giant planets are just as capable of carving out g…
How Spirals and Gaps Driven by Companions in Protoplanetary Disks Appear in Scattered Light at Arbitrary Viewing Angles
Ruobing Dong, Jeffrey Fung, Eugene Chiang
Direct imaging observations of protoplanetary disks at near-infrared (NIR) wavelengths have revealed structures of potentially planetary origin. Investigations of observational sig…
