Sound Velocity and Grüneisen Parameter in Shock‐Melted Silica at Deep Earth Pressures
Journal of Geophysical Research: Solid Earth, Volume 130, Issue 9, September 2025.Abstract Silica is a primary component of rocky planet interiors and its melt properties are important for understanding planetary formation and differentiation, magma oceans, and the deep mantle. Although well understood in the solid state, the high‐pressure behavior of liquid silica is poorly constrained at lower mantle pressures.

Breaking Giant Chains: Early-stage Instabilities in Long-period Giant Planet Systems
The Astrophysical JournalOrbital evolution is a critical process that sculpts planetary systems, particularly during their early stages where planet–disk interactions are expected to lead to the formation of resonant chains.

Asteroseismology of exoplanets host stars: the special case of $\iota$ Horologii (HD17051)
, 2006 {This paper presents detailed analysis and modelisation of the star HD17051 (alias $\iota$ Hor), which appears as a specially interesting case among exoplanet host stars.

Comparing Geochemical and Geodynamical Models of Plume and Ridge Mantle Source Composition
Geochemistry, Geophysics, Geosystems, Volume 26, Issue 8, August 2025.Abstract We use a multidisciplinary approach to investigate how the parameter space of mantle convection affects present‐day mantle composition. We compare 22 forward geodynamical mantle circulation model simulations against 24 variants of a geochemical inversion model of the global radiogenic isotope data set of mantle‐derived lavas.

Three-dimensional Orbital Architectures and Detectability of Adjacent Companions to Hot Jupiters
The Astrophysical JournalThe orbital properties of the (as yet) small population of hot Jupiters with nearby planetary companions provide valuable constraints on the past migration processes of these systems.

Orbital Dynamics of Multi-Planet Systems with Eccentricity Diversity
, 2014 Since exoplanets were detected using the radial velocity method, they have revealed a diverse distribution of orbital configurations. Amongst these are planets in highly eccentric orbits (e > 0.5).

, 2013 The hundreds of exoplanets that have been discovered in the past two decades offer a new perspective on planetary structure. Instead of being the archetypal examples of planets, those of our Solar System are merely possible outcomes of planetary system ...

Radial Velocities as an Exoplanet Discovery Method
, 2017 The precise radial velocity technique is a cornerstone of exoplanetary astronomy. Astronomers measure Doppler shifts in the star's spectral features, which track the line-of/sight gravitational accelerations of a star caused by the planets orbiting it ...
