Infall Explains the Disk Kinematics of AB Aur Without Gravitational Instability
Josh Calcino, Daniel J. Price, Chris W. Ormel
Late-stage infall onto protoplanetary disks can produce large scale spiral arms. In this paper we used 3D smoothed particle hydrodynamics and radiative transfer simulations to stud…
A Cloudy Fit to the Atmosphere of WASP-107 b
Helong Huang, Michiel Min, Chris W. Ormel +2
Context. WASP-107 b has been observed comprehensively by JWST in the near- and mid-IR bands, making it an ideal planet to probe the composition and internal dynamics. Recent analys…
Dust and Water in V883 Ori: Relics of a Retreating Snowline
Yu Wang, Chris W. Ormel, Hao-Chang Jiang +3
V883 Ori is an FU-Orionis-type outburst system characterized by a shoulder at 50-70 au in its ALMA band 6 and 7 intensity profiles. Previously, this feature was attributed to dust…
A Resonant Beginning for the Solar System Terrestrial Planets
Shuo Huang, Chris Ormel, Simon Portegies Zwart +2
In the past two decades, transit surveys have revealed a class of planets with thick atmospheres -- sub-Neptunes -- that must have completed their accretion in protoplanet disks. W…
From Planetesimals to Dwarf Planets by Pebble Accretion
Chris W. Ormel, Yukun Huang
The size distribution of TNOs in the Kuiper Belt provides crucial insights into the formation and evolution of the outer Solar System. Recent observational surveys, including OSSOS…
The Dynamical History of the Kepler-221 Planet System
Tian Yi, Chris W. Ormel, Shuo Huang +1
Kepler-221 is a G-type star hosting four planets. In this system, planets b, c, and e are in (or near) a 6:3:1 three-body resonance even though the planets' period ratios show sign…
