Self-consistent Spin, Tidal, and Dynamical Equations of Motion in the REBOUNDx Framework

The Astrophysical Journal, 2023
We introduce self-consistent spin, tidal, and dynamical equations of motion into REBOUNDx , a library of additional effects for the popular N -body integrator REBOUND .

Self-consistent Dynamical and Chaotic Tides in the REBOUNDx Framework

The Astrophysical Journal
At high eccentricities, tidal forcing excites vibrational modes within orbiting bodies known as dynamical tides. In this paper, we implement the coupled evolution of these modes with the body’s orbit in the REBOUNDx framework, an extension to the popular

Effects of Hydrogen on Fe‐S Alloys and Their Implications for the Martian Core

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract Meteorites suggest the Martian core comprises iron (Fe) or iron‐nickel (Fe‐Ni) alloy with sulfur (S) identified as the primary light element. The InSight data revealed a larger, less dense Martian core than previously estimated, indicating additional light elements.

HARPS-N @ TNG, two year harvesting data : performances and results [PDF]

, 2014
The planet hunter HARPS-N[1], in operation at the Telescopio Nazionale Galileo (TNG)[13] from April 2012 is a highresolution spectrograph designed to achieve a very high radial velocity precision measurement thanks to an ultra stable environment and in a

Thermally Regulated Viscoelastic Tidal Migration of Eccentric Planets

The Astrophysical Journal Letters
A growing population of short-period Neptune-like planets has nonzero eccentricities and, in some cases, large stellar obliquities, suggestive of high-eccentricity migration. Modeling this evolution requires a prescription for tidal dissipation, which in

A Cross‐Correlation Method to Evaluate Wind Retrieval Accuracy on Mars Using Simulated Microwave Limb Sounder Observations

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract While aspects such as the temperature and composition of the Martian atmosphere are relatively well known thanks to observations from numerous space missions, Martian atmospheric dynamics remain poorly constrained due to the scarcity of direct wind measurements. The use of microwave limb sounders to retrieve winds has been proposed in the past,

Tidally Torn: Why the Most Common Stars May Lack Large, Habitable-zone Moons

The Astronomical Journal
Earth-like planets in the habitable zone (HZ) of M dwarfs have recently been targeted in the search for exomoons. We study the stability and lifetime of large (Luna-like) moons, accounting for the effects of three-body interactions and tidal forces using

Satellites and Small Bodies With ALMA: Insights Into Solar System Formation and Evolution

AGU Advances, Volume 6, Issue 6, December 2025.
Abstract Our understanding of the formation and evolution of planetary systems has made major advances in the past decade. This progress has been driven in large part by the Atacama Large Millimeter/submillimeter Array (ALMA), which has given us an unprecedented view of solar system bodies themselves, and of the structure and chemistry of forming ...

Coupled Planetary Interior and Tidal Evolution

The Astrophysical Journal
We present a new planetary structure/thermal evolution model, designed for use in problems that couple orbital dynamics with planetary structure. We first benchmark our structural/thermal evolution calculations against the MESA stellar evolution code ...
