Exoplanet winds: Modelling atmospheric dynamics via resolved spectral lines
, 2021 This thesis benchmarked a new probe of atmospheric dynamics in exoplanet atmospheres by resolving the spectral lines stemming from these far atmospheres and then modelling their line shape taking into account the broadening from atmospheric winds. This gives us a window into atmospheric winds for these far away worlds only limited by the depths of the ...

Early Time Small-scale Structures in Hot Exoplanet Atmosphere Simulations
The Astrophysical JournalWe report on the critical influence of small-scale flow structures (e.g., fronts, vortices, and waves) that immediately arise in hot exoplanet atmosphere simulations initialized with a resting state.

On the Detection of Low‐Frequency Planetary Radio Emission With an Orbiting Interferometer
Radio Science, Volume 61, Issue 6, June 2026.Abstract The magnetized planets of the outer Solar System produce kilometric radio emissions at very low frequencies (<1 ${< } 1\,$MHz). They reveal the planetary magnetic dynamics and their interaction with the solar wind. Those radio emissions can also serve as a proxy for interplanetary space weather monitoring.

Exoplanetary atmosphere target selection in the era of comparative planetology [PDF]
, 2019 The large number of new planets expected from wide-area transit surveys means that follow-up transmission spectroscopy studies of their atmospheres will be limited by the availability of telescope assets.

The Role of Planetary Rotation in Polar Cusp Localization
Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.Abstract Juno observations have revealed that Jupiter's polar cusps are displaced toward dusk and even the nightside, contradicting the Earth‐derived paradigm that is confined to narrower ranges near noon. These findings underscore the overlooked influence of planetary rotation on magnetospheric dynamics, exposing a critical gap in current theoretical ...

Helium Escape in Context: Comparative Signatures of Four Close-in Exoplanets
The Astrophysical JournalObservations of escaping atmospheres on close-in exoplanets show a wide range in the strength and morphology of He I 10830 Å and H I absorption. Scaling relations attempt to link the He I signal to X-ray and UV irradiation, mass loss, and bulk planetary ...

Hot Spot Offset Variability from Magnetohydrodynamical Thermoresistive Instability in Hot Jupiters
The Astrophysical JournalHot Jupiter (HJ) atmospheres are possibly subject to a thermoresistive instability (TRI). Such an instability may develop as the ohmic heating increases the electrical conductivity in a positive feedback loop, which ultimately leads to a runaway of the ...
