Shock Compression of Coesite up to 950 GPa

Geophysical Research Letters, Volume 51, Issue 24, 28 December 2024.
Abstract Experimental investigations of silica under high pressure and temperature offer crucial insights into modeling of Earth and super‐Earths’ interiors. Despite extensive studies on Hugoniots of silica polymorphs like fused‐silica (2.20 g/cm3), quartz (2.65 g/cm3) and stishovite (4.29 g/cm3) up to a terapascal, unexplored region of melting and ...

Multiplicity-Study of Exoplanet Host Stars [PDF]

arXiv, 2005
We carry out a systematic search campaign for wide companions of exoplanet host stars to study their multiplicity and its influence on the long-term stability and the orbital parameters of the exoplanets. We have already found 6 wide companions, raising the number of confirmed binaries among the exoplanet host stars to 20 systems. We have also searched

The Process We Call Earth: Relationships Between Dynamic Feedbacks and the Search for Gaiasignatures in a New Paradigm of Earthlikeness

Perspectives of Earth and Space Scientists, Volume 5, Issue 1, December 2024.
Abstract Standard notions of an “Earthlike” planet rely solely on physical and material properties, like planetary mass, radius, and surface temperature. Here, we introduce a novel, relational perspective on what defines “Earthlikeness.” In our process‐based framework, rocky planets are local pockets of free energy that have the potential to drive the ...

Keplerian Orbits and Dynamics of Exoplanets [PDF]

Exoplanets, 2010, 526 pp., p.15-23, 2010
Understanding the consequences of the gravitational interaction between a star and a planet is fundamental to the study of exoplanets. The solution of the two-body problem shows that the planet moves in an elliptical path around the star and that each body moves in an ellipse about the common center of mass.

Solar System Ice Giants: Exoplanets in our Backyard

, 2018
Future remote sensing of exoplanets will be enhanced by a thorough investigation of our solar system Ice Giants (Neptune-size planets). What can the configuration of the magnetic field tell us (remotely) about the interior, and what implications does that field have for the structure of the magnetosphere; energy input into the atmosphere, and surface ...

Peas-in-a-pod across the Radius Valley: Rocky Systems Are Less Uniform in Mass but More Uniform in Size and Spacing

The Astrophysical Journal Letters
The ubiquity of “peas-in-a-pod” architectural patterns and the existence of the radius valley each presents a striking population-level trend for planets with R _p ≤ 4 R _⊕ that serves to place powerful constraints on the formation and evolution of these

Simultaneous characterization of the atmospheres, surfaces, and exomoons of nearby rocky exoplanets

Earth and Planetary Physics, 2018
Atmospheric composition is an important indicator of habitability and life. The presence or absence of a large exomoon around an Earth-size exoplanet could have important consequences for planet climate stability.
