Oxygen fugacities of extrasolar rocks: Evidence for an Earth-like geochemistry of exoplanets [PDF]
Science, 2019 Peering inside extrasolar rocky bodies The oxygen fugacity of a rock, fO2, is a measure of how oxidizing or reducing its surroundings were when the rock formed.

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2012 Exoplanets—planets orbiting around stars other than our own Sun—appear to be common. Significant research effort is now focused on the observation and characterization of exoplanet atmospheres. Species such as water vapour, methane, carbon monoxide and carbon dioxide have been observed in a handful of hot, giant, gaseous planets, but ...

Robo-AO and SOAR High-Resolution Surveys of Exoplanet Hosting Stars
Frontiers in Astronomy and Space Sciences, 2021 In the past decade, space-based transit surveys have delivered thousands of potential planet-hosting systems. Each of these needs to be vetted and characterized using follow-up high-resolution imaging.

The Detection and Characterization of Extrasolar Planets
Challenges, 2014 We have now confirmed the existence of > 1800 planets orbiting stars other thanthe Sun; known as extrasolar planets or exoplanets. The different methods for detectingsuch planets are sensitive to different regions of parameter space, and so, we are ...

Atmospheric Escape and the Evolution of Close-In Exoplanets [PDF]
Annual Review of Earth and Planetary Science, 2018 Exoplanets with substantial hydrogen/helium atmospheres have been discovered in abundance, many residing extremely close to their parent stars.

Theoretical models of planetary system formation. II. Post-formation evolution [PDF]
, 2015 We extend the results of planetary formation synthesis by computing the long-term evolution of synthetic systems from the clearing of the gas disk into the dynamical evolution phase.

A Cubesat Payload for Exoplanet Detection
Sensors, 2017 The search for undiscovered planets outside the solar system is a scientific topic that is rapidly spreading into the astrophysical and engineering communities. In this framework, the design of an innovative payload to detect exoplanets from a nano-sized

Theoretical Spectra of Terrestrial Exoplanet Surfaces [PDF]
, 2012 We investigate spectra of airless rocky exoplanets with a theoretical framework that self-consistently treats reflection and thermal emission. We find that a silicate surface on an exoplanet is spectroscopically detectable via prominent Si-O features in ...
