Imaging Cool Giant Planets in Reflected Light: Science Investigations and Synergy with Habitable Planets [PDF]

, 2019
Planned astronomical observatories of the 2020s will be capable of obtaining reflected light photometry and spectroscopy of cool extrasolar giant planets.

Characteristics of solar-like oscillations in red giants observed in the CoRoT exoplanet field

, 2009
Observations during the first long run (~150 days) in the exo-planet field of CoRoT increase the number of G-K giant stars for which solar-like oscillations are observed by a factor of 100. This opens the possibility to study the characteristics of their

Evolution of Terrestrial Planetary Bodies and Implications for Habitability

Reviews of Geophysics, Volume 63, Issue 4, December 2025.
Abstract The terrestrial planetary bodies of our solar system—Mercury, Venus, Earth, and Mars—share a common origin through nebular accretion and early magma ocean differentiation, yet they diverged significantly in geological evolution, tectonic regimes, and habitability.

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 ...

Precision Stellar Astrophysics in the Kepler Era

, 2016
The study of fundamental properties (such as temperatures, radii, masses, and ages) and interior processes (such as convection and angular momentum transport) of stars has implications on various topics in astrophysics, ranging from the evolution of ...

Constraining Exoplanet Structure and Composition: Linking Theory & Observations

, 2022
Since the discovery of first exoplanet by the end of the twentieth century, technological advancements have hugely extended our understanding of planetary systems. The large number of discovered exoplanets has unveiled a staggering diversity in their nature, leading to the surprising conclusion that our Solar System may not be a typical system.

Climate Emergency and Different Ways to Fail? The Fermi Paradox, the Simulation Hypothesis, Agency and Hope

Journal for the Theory of Social Behaviour, Volume 55, Issue 4, December 2025.
ABSTRACT Humanity seems stuck on different ways to fail to meet the challenge posed by a declared climate emergency and manifest problems of ecological breakdown. Rather than reprise these failures, we use the Fermi Paradox and simulation hypothesis to make a simple point about agency. The argument unfolds in two sections.

A Temperature and Abundance Retrieval Method for Exoplanet Atmospheres

, 2009
We present a new method to retrieve molecular abundances and temperature profiles from exoplanet atmosphere photometry and spectroscopy. We run millions of 1D atmosphere models in order to cover the large range of allowed parameter space, and present ...

Evolution of Steam Worlds: Energetic Aspects

The Astrophysical Journal
Sub-Neptunes occupy an intriguing region of planetary mass–radius space, where theoretical models of interior structure predict that they could be water-rich, where water is in steam and supercritical state.

Transit Photometry as an Exoplanet Discovery Method

, 2018
Photometry with the transit method has arguably been the most successful exoplanet discovery method to date. A short overview about the rise of that method to its present status is given.
