Exoplanet interiors and habitability [PDF]

Advances in Physics: X, 2019
More than 1000 exoplanets with a radius smaller than twice that of the Earth are currently known, mainly thanks to space missions dedicated to the search of exoplanets. Mass and radius estimates, which are only available for a fraction (∼ 10%) of the exoplanets, provide an indication of the bulk composition and interior structure and show that the ...

Kepler Observations of the Three Pre-Launch Exoplanet Candidates: Discover of Two Eclipsing Binaries and a New Exoplanet [PDF]

, 2010
Three transiting exoplanet candidate stars were discovered in a ground-based photometric survey prior to the launch of NASA's Kepler mission. Kepler observations of them were obtained during Quarter 1 of the Kepler mission.

Using near infra-red spectroscopy for characterization of transiting exoplanets

, 2015
We propose a method for observing transiting exoplanets with near-infrared high-resolution spectrometers. We aim to create a robust data analysis method for recovering atmospheric transmission spectra from transiting exoplanets over a wide wavelength ...

The role of boundary‐layer friction in modulating midlatitude heatwaves

Quarterly Journal of the Royal Meteorological Society, Volume 151, Issue 768, April 2025 Part A.
Boundary‐layer friction associated with different surface types plays an important role in modulating heatwaves in the midlatitudes. The main changes in heatwave features occur when locally modifying boundary‐layer friction along the jet‐stream axis. Real‐world differences in the occurrence of heatwaves between different locations in the midlatitudes ...

Tracing the Contribution of Abiotic Methane in Deep Natural Gases From the Songliao Basin, China Using Bulk Isotopes and Methane Clumped Isotopologue 12CH2D2

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 4, April 2025.
Abstract The identification and evaluation of abiotic methane remain an active research area due to uncertainties in traditional indicators that may lead to “false‐positive” detections. As an emerging isotopic tool, methane clumped isotope can provide novel information about the generation and post‐generation processes of methane gases.

Characterizing Exoplanet Habitability [PDF]

, 2017
A habitable exoplanet is a world that can maintain stable liquid water on its surface. Techniques and approaches to characterizing such worlds are essential, as performing a census of Earth-like planets that may or may not have life will inform our understanding of how frequently life originates and is sustained on worlds other than our own ...

A Quantitative Comparison of Exoplanet Catalogs

Geosciences, 2018
In this study, we investigated the differences between four commonly-used exoplanet catalogs (exoplanet.eu; exoplanetarchive.ipac.caltech.edu; openexoplanetcatalogue.com; exoplanets.org) using a Kolmogorov–Smirnov (KS) test.

Thermophysical States of MgSiO3 Liquid up to Terapascal Pressures: Implications for Magma Oceans in Super‐Earths and Sub‐Neptunes

Journal of Geophysical Research: Planets, Volume 130, Issue 4, April 2025.
Abstract Thermophysical properties of silicate liquids under extreme conditions are critical for understanding the accretion and evolution of super‐Earths and sub‐Neptunes. The thermal equation of state and viscosity of silicate liquids determine the adiabatic profiles and dynamics of magma oceans. However, these properties are challenging to constrain

The Search for Stellar Companions to Exoplanet Host Stars Using the CHARA Array

, 2008
Most exoplanets have been discovered via radial velocity studies, which are inherently insensitive to orbital inclination. Interferometric observations will show evidence of a stellar companion if it sufficiently bright, regardless of the inclination ...
