Prebiosignature Molecules Can Be Detected in Temperate Exoplanet Atmospheres with JWST [PDF]
Astronomical Journal, 2023 The search for biosignatures on exoplanets connects the fields of biology and biochemistry to astronomical observation, with the hope that we might detect evidence of active biological processes on worlds outside the solar system.

Classification of Trajectories in a Two-planet Exosystem Using the Generalized Three-body Problem
The Astrophysical Journal, 2023 We deploy the theory of the generalized three-body problem to describe an exosystem composed of a host star, a transiting Jupiter-sized exoplanet, and an Earth-sized exoplanet.

Classify and Explore the Diversity of Planetary Population and Interior Properties
The Astrophysical Journal, 2023 Classification is an essential method and has been developed widely in astronomy. However, planets still lack a universal classification framework, because the solar system planet sample is too small for statistical analysis.

Fizzy Super-Earths: Impacts of Magma Composition on the Bulk Density and Structure of Lava Worlds
The Astrophysical Journal, 2023 Lava worlds are a potential emerging population of Super-Earths that are on close-in orbits around their host stars, with likely partially molten mantles. To date, few studies have addressed the impact of magma on the observed properties of a planet.

Age Distribution of Exoplanet Host Stars: Chemical and Kinematic Age Proxies from GAIA DR3 [PDF]
Astronomical Journal, 2023 The GAIA space mission is impacting astronomy in many significant ways by providing a uniform, homogeneous, and precise data set for over 1 billion stars and other celestial objects in the Milky Way and beyond.

Kepler-80 Revisited: Assessing the Participation of a Newly Discovered Planet in the Resonant Chain
The Astronomical Journal, 2023 In this paper, we consider the chain of resonances in the Kepler-80 system and evaluate the impact that the additional member of the resonant chain discovered by Shallue & Vanderburg has on the dynamics of the system and the physical parameters that can ...
