Atmospheric Escape and the Evolution of Close-In Exoplanets [PDF]
Annual Review of Earth and Planetary Sciences, 2019 Exoplanets with substantial hydrogen/helium atmospheres have been discovered in abundance, many residing extremely close to their parent stars. The extreme irradiation levels that these atmospheres experience cause them to undergo hydrodynamic atmospheric escape.

The Possible Evolution of an Exoplanet’s Atmosphere
Eos, 2021 Scientific sleuths explore data gathered trillions of kilometers away and put forth different, and often conflicting, ideas to reconstruct the gaseous envelope on a distant rocky exoplanet, GJ 1132 b.

Investigating Exoplanet Orbital Evolution Around Binary Star Systems with Mass Loss [PDF]
Journal of Astronomy and Space Sciences, 2016 A planet revolving around binary star system is a familiar system. Studies of these systems are important because they provide precise knowledge of planet formation and orbit evolution. In this study, a method to determine the evolution of an exoplanet

Effect of Laboratory Reagents for Cleaning Modern Contamination on the δ<sup>15</sup>N Integrity of Nitrogen-Poor Samples. [PDF]
Rapid Commun Mass SpectromABSTRACT Rationale Nitrogen isotope values have been widely used for tracing ancient biogeochemical processes, but contaminant‐sensitive materials, such as Precambrian sedimentary rocks, meteorites, or returned extraterrestrial samples, often have low nitrogen levels and are thus vulnerable to modern organic contamination.

Mapping out the time-evolution of exoplanet processes [PDF]
, 2019 There are many competing theories and models describing the formation, migration and evolution of exoplanet systems. As both the precision with which we can characterize exoplanets and their host stars, and the number of systems for which we can make such a characterization increase, we begin to see pathways forward for validating these theories.

True Polar Wander of Lava Worlds
The Astrophysical Journal Letters, 2023 As one of the most detectable types of terrestrial planets, lava worlds are highly prioritized targets for exoplanet atmosphere characterization since their atmospheres may reveal what they are made of and how.

Evolution of exoplanets and their parent stars [PDF]
EAS Publications Series, 2014 Studying exoplanets with their parent stars is crucial to understand their population, formation and history. We review some of the key questions regarding their evolution with particular emphasis on giant gaseous exoplanets orbiting close to solar-type stars.
