The Demographics of Terrestrial Planets in the Venus Zone

The Astronomical Journal, 2023
Understanding the physical characteristics of Venus, including its atmosphere, interior, and its evolutionary pathway with respect to Earth, remains a vital component for terrestrial planet evolution models and the emergence and/or decline of planetary ...

Relative habitability of exoplanet systems with two giant planets

Monthly Notices of the Royal Astronomical Society, 2022
ABSTRACT The architecture of a planetary system can influence the habitability of a planet via orbital effects, particularly in the areas of stability and eccentricity. Some of these effects are readily apparent, particularly when they occur on short time-scales that are easily numerically calculable.

Exoplanet characterization using conditional invertible neural networks [PDF]

, 2023
Context. The characterization of the interior of an exoplanet is an inverse problem. The solution requires statistical methods such as Bayesian inference.

The K2 and TESS Synergy. II. Revisiting 26 Systems in the TESS Primary Mission

The Astronomical Journal, 2023
The legacy of NASA’s K2 mission has provided hundreds of transiting exoplanets that can be revisited by new and future facilities for further characterization, with a particular focus on studying the atmospheres of these systems. However, the majority of

Dynamical Mass Demography of Single S-type Planets Shaped by Stellar Companions

The Astrophysical Journal Supplement Series
More than 700 S-type (satellite-type orbit) planets have been identified from Gaia and TESS observations, including over 150 transiting targets, enabling precise dynamical orbits and planetary mass characterization in binary environments. Here we present

Mesoscale Modeling of Titan’s Shangri‐La Region: The Impact of Surface Properties on Winds

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract The knowledge of Titan’s near‐surface atmosphere is sparse. The Huygens descent probe measured winds, and the multiple dune field observations and possible dust storms suggest active near‐surface dynamics. The Dragonfly rotorcraft lander will fly close to the surface in the Shangri‐La region, near the Huygens landing site, where complex dune ...

Statistical Distribution Function of Orbital Spacings in Planetary Systems

The Astronomical Journal
The minimum orbital separation of planets in long-stable planetary systems is often modeled as a step function, parameterized with a single value ${{\rm{\Delta }}}_{\min }$ (measured in mutual Hill radius of the two neighboring planets).

Propagation Dynamics of Fast Electron Beam and Its Electron Cyclotron Maser Emission

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract Fast electron beams (FEBs) and coherent radio bursts both are very common plasma activity phenomena in the cosmos. The electron cyclotron maser (ECM) instability driven by FEBs trapped in magnetic fields can directly amplify radio wave radiations.

Disrupted Exoplanet Systems in the SuperWASP Archive [PDF]

, 2020
The aim of this research project has been to search for disrupted or disintegrating exoplanets; this search has been carried out using archival data from the Super-WASP (Wide Angle Search for Planets) transit photometry detection programme. The main aim of the archival search was to look for objects similar to Kepler-1520b (Rappaport et al., 2012) and ...
