The Dynamics of Planetary Ejection
Malena Rice, William DeRocco, Sean N. Raymond
The ubiquity of free-floating planets inferred from microlensing and direct imaging surveys suggests that planetary ejection---a process in which planets initially born encircling…
On the Eccentricity Distribution and Tidal Evolution of Transiting Brown Dwarfs
Thiago Ferreira, Malena Rice
Brown dwarfs on short-period orbits populate an intermediate regime between hot Jupiters and tight stellar binaries, lying at the intersection of possible evolutionary avenues. The…
The Architecture of the 14 Herculis System Suggests Primordial Ejection of a Massive Planet
Tiger Lu, Sarah C. Millholland, Malena Rice +6
The 14 Herculis system hosts two super-Jupiters on eccentric, significantly misaligned orbits. This orbital architecture represents a dynamical puzzle that demands explanation. In…
Chemistry and Isotope Ratios of Substellar Atmospheres in the Pictoris Young Moving Group and Vicinity
Yurou Liu, Yapeng Zhang, Jerry W. Xuan +7
Measuring the chemical and isotopic compositions of gas giants and brown dwarfs provides insights into their formation pathways and birth environments. 2MASS J0249-0557 c is an L2-…
Hot Jupiters' Isolation Is Not Unique to High-Eccentricity Tidal Migration
Brandon Radzom, Songhu Wang, Bonan Pu +2
Conventionally, the observed isolation of hot Jupiters, marked by a paucity of nearby low-mass planetary companions, has been interpreted as evidence of high-eccentricity tidal mig…
Confirmation of Fe I on MASCARA-5 b's Dayside Observed With EXPRES
James T. Sikora, Joe Llama, Rachael M. Roettenbacher +5
MASCARA-5~b/TOI-1431~b is an ultra-hot Jupiter \citep[, , , $R_{\rm p}=…
Observational and Dynamical Constraints on an Unseen Outer Perturber in the GJ 436 Hot Neptune System
Haedam Im, Tiger Lu, Malena Rice +3
Hot Neptunes in the sub-Jovian desert offer unique insights into planetary system evolution, retaining signatures of dynamical processes that shaped their present-day architectures…
