Detecting Secular Perturbations in Kepler Planetary Systems Using Simultaneous Impact Parameter Variation Analysis (SIPVA) Open
Recovering impact parameter variations in multi-planet systems is an effective approach for detecting non-transiting planets and refining planetary mass estimates. Traditionally, two methodologies have been employed: the Individual Fit, wh…

The Aligned Orbit of WASP-148b, the Only Known Hot Jupiter with a nearby Warm Jupiter Companion, from NEID and HIRES Open
We present spectroscopic measurements of the Rossiter–McLaughlin effect for WASP-148b, the only known hot Jupiter with a nearby warm-Jupiter companion, from the WIYN/NEID and Keck/HIRES instruments. This is one of the first scientific resu…

SOLES II: The Aligned Orbit of WASP-148b, the Only Known Hot Jupiter with a Nearby Warm Jupiter Companion, from NEID and HIRES Open

Strong scatterings of cold Jupiters and their influence on inner low-mass planet systems: theory and simulations Open
Recent observations have indicated a strong connection between compact (a ≲ 0.5 au) super-Earth and mini-Neptune systems and their outer (a ≳ a few au) giant planet companions. We study the dynamical evolution of such inner systems subject…
Giant planet scatterings and collisions: hydrodynamics, merger-ejection branching ratio, and properties of the remnants Open
Planetary systems with sufficiently small orbital spacings can experience planetary mergers and ejections. The branching ratio of mergers versus ejections depends sensitively on the treatment of planetary close encounters. Previous works h…
In situ scattering of warm Jupiters and implications for dynamical histories Open
Many warm Jupiters (WJs) have substantial eccentricities, which are linked to their formation and migration histories. This paper explores eccentricity excitation of WJs due to planet–planet scattering, beginning with three to four planets…
Low-eccentricity migration of ultra-short-period planets in multiplanet systems Open
Recent studies suggest that ultra-short-period planets (USPs), Earth-sized planets with sub-day periods, constitute a statistically distinct sub-sample of Kepler planets: USPs have smaller radii (1–1.4R⊕) and larger mutual inclinations wit…
Eccentricities and inclinations of multiplanet systems with external perturbers Open
Compact multi-planet systems containing super-Earths or sub-Neptunes,\ncommonly found around solar-type stars, may be surrounded by external giant\nplanet or stellar companions, which can shape the architechture and\nobservability of the i…
How do external companions affect spin–orbit misalignment of hot Jupiters? Open
Consider a planet with its orbital angular momentum axis aligned with the\nspin axis of its host star. To what extent does an inclined distant companion\n(giant planet or binary star) affect this alignment? We provide an analytic,\nquantit…
