Collisional Fragmentation Support in TRACE
Tiger Lu, Haniyeh Tajer, David M. Hernandez +3
We present improved collision support for TRACE, a state-of-the-art hybrid integrator in REBOUND. TRACE now supports collisional fragmentation and can handle both removing and addi…
squishyplanet: Modeling Transits of Non-spherical Exoplanets in JAX
Ben Cassese, Justin Vega, Tiger Lu +3
While astronomers often assume that exoplanets are perfect spheres when analyzing observations, the subset of these distant worlds that are subject to strong tidal forces and/or ra…
Significant mutual inclinations between the stellar spin and the orbits of both planets in the HAT-P-11 system
Qier An, Tiger Lu, G. Mirek Brandt +2
Planet-star obliquity and planet-planet ]mutual inclination encode a planetary system's dynamical history, but both of their values are hard to measure for misaligned systems with…
Planet-Planet Scattering and ZLK Migration -- The Dynamical History of HAT-P-11
Tiger Lu, Qier An, Gongjie Li +4
The two planets of the HAT-P-11 system represent fascinating dynamical puzzles due to their significant eccentricities and orbital misalignments. In particular, HAT-P-11 b is on a…
JWST Coronagraphic Images of 14 Her c: a Cold Giant Planet in a Dynamically Hot, Multi-planet System
Daniella C. Bardalez Gagliuffi, William O. Balmer, Laurent Pueyo +16
Most observed multi-planet systems are coplanar, in a dynamically "cold" configuration of concentric orbits like our own Solar System. With the James Webb Space Telescope (JWST) we…
The Dynamical History of HIP-41378 f -- Oblique Exorings Masquerading as a Puffy Planet
Tiger Lu, Gongjie Li, Ben Cassese +1
The super-puff HIP-41378 f represents a fascinating puzzle due to its anomalously low density on a far-out orbit in contrast with other known super-puffs. In this work, we explore…
