Modeling the Seasonality of Wind‐Driven Hydrocarbon Waves in Titan's Polar Lakes

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Titan, the only body in the solar system aside from Earth with standing liquids on its surface, has high‐latitude hydrocarbon lakes and seas. As Titan's atmosphere generates light winds, there should be waves on the surface of these lakes and seas, yet, direct wave observations are scant.

ATMOSPHERIC CHEMISTRY OF VENUS-LIKE EXOPLANETS [PDF]

The Astrophysical Journal, 2011
We use thermodynamic calculations to model atmospheric chemistry on terrestrial exoplanets that are hot enough for chemical equilibira between the atmosphere and lithosphere, as on Venus. The results of our calculations place constraints on abundances of spectroscopically observable gases, the surface temperature and pressure, and the mineralogy of the

Clouds in Partial Atmospheres of Lava Planets and Where to Find Them

The Astronomical Journal
With dayside temperatures hot enough to sustain a magma ocean and a silicate atmosphere, lava planets are the best targets for studying the atmosphere of a rocky world.

Observations of Exoplanet Atmospheres and Surrounding Environments

, 2014
The study of exoplanets is arguably the most exciting and fastest-growing field in astrophysics. Given the youth of exoplanet science, the field is strongly driven by observations.

Volcanism at Piton de la Fournaise as an Analog for Chloris Mons, Venus

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Identifying and investigating terrestrial analogs for Venus volcanic activity is necessary to prepare for the planned upcoming missions to Venus. We propose volcanism at Piton de la Fournaise, a frequently active oceanic shield volcano, as an analog to volcanism at Chloris Mons, Venus.

Characterizing the Atmospheric Dynamics of HD 209458b-like Hot Jupiters Using AI-driven Image Recognition/Categorization

The Astrophysical Journal, 2023
In order to understand the results of recent observations of exoplanets, models have become increasingly complex. Unfortunately, this increases both the computational cost and output size of said models.

Impacts of Carbon Dioxide Deposition on Martian Near‐Surface Wave Activity

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract A prominent feature of Mars' winter atmosphere is near‐surface baroclinic wave activity. These waves exert strong control on dust storm variability and contribute to transport of heat, momentum, and dust. Using a suite of Mars general circulation model simulations, we investigate an underexplored connection between near‐surface wave activity ...

Spectral Retrieval with JWST Photometric data: a Case Study for HIP 65426 b

The Astronomical Journal, 2023
Half of the JWST high-contrast imaging objects will only have photometric data as of Cycle 2. However, to better understand their atmospheric chemistry that informs formation origin, spectroscopic data are preferred.

Towards Generalized Characterization of Exoplanet Atmospheres with Transit Spectroscopy

, 2021
The field of exoplanetary sciences has grown from an era of detection to one of characterization. To date, over 4000 exoplanets have been discovered and over 50 of them have been observed with primary transit spectroscopy methods.

Deciphering the “Missing Xenon Paradox” in Celestial Bodies: A Multifaceted Perspective Toward Demystifying This Enigma

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract Xenon (Xe) is a heavy noble gas with intriguing chemical properties, such as having several stable isotopes and the ability to form compounds under extreme conditions. Despite the predictions based on cosmochemical models that suggest xenon should be relatively abundant in planetary reservoirs, empirical data indicate a significant depletion ...
