Exoplanets and Radio Astronomy Beyond Earth [PDF]
2021 XXXIVth General Assembly and Scientific Symposium of the International Union of Radio Science (URSI GASS), 2021 Jupiter's radio emission has been linked to its planetary-scale magnetic field, and spacecraft investigations have revealed that most planets, and some moons, have or had a global magnetic field. Generated by internal dynamos, magnetic fields are one of the few remote sensing means of constraining the properties of planetary interiors.

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.

The Astronomical Journal, 2023 A microlensing event is mainly used to search for free-floating planets (FFPs). To estimate the FFP mass and distance via the microlensing effect, a microlensing parallax is one of the key parameters.

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.

The Astronomical Journal, 2023 We present a validation of a long-period ( ${91.68278}_{-0.00041}^{+0.00032}$ days) transiting sub-Neptune planet, TOI-1221 b (TIC 349095149.01), around a Sun-like ( m _V = 10.5) star.

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 ...

New Astronomy Reviews special issue: History of Kepler’s major exoplanet “firsts” [PDF]
New Astronomy Reviews, 2018 NASA's Kepler Mission revolutionized exoplanet science in the early part of the 2010's. Looking back from the perspective of the end of that decade, Kepler appears to have burst upon the scene ready for battle, like Athena springing forth, fully formed, from the head of Zeus. The story was not so simple.
