Modeling Wind‐Driven Waves on Other Planets: Applications to Mars, Titan, and Exoplanets

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract Waves could exist on any planet with sustained winds and stable surface liquids. However, differences in atmospheres, liquids, and gravity confound efforts to extend Earth‐based empirical wave models to other planetary environments. We adapted a physics‐based numerical wave model to study how planetary conditions affect the growth of waves. We

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

open access: yesThe 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.

On the Stability of Super-Earth Atmospheres

open access: yes, 2012
We investigate the stability of super Earth atmospheres around M stars using a 7-parameter, analytical framework. We construct stability diagrams in the parameter space of exoplanetary radius versus semi-major axis and elucidate the regions in which the ...

Exoplanet Atmospheres with JWST

open access: yes, 2022
Planetary atmospheres are diverse. They hold key insights into the complex physics and chemistry that has shaped them through formation. In this talk I focus on the understanding we have gained on exoplanet atmospheres from transiting studies, including the importance of wide wavelength coverage.

The Bochum Survey of the Southern Galactic Disk: III. Complete Data Release

open access: yesAstronomische Nachrichten, Volume 347, Issue 3, March 2026.
ABSTRACT The Southern Galactic Disk Survey (GDS) monitored a mosaic of 268 fields along a 6°$$ {6}^{{}^{\circ}} $$‐wide stripe in the southern Galactic disk with simultaneous observations in r′$$ {r}^{\prime } $$ and i′$$ {i}^{\prime } $$ (7m≲r′,i′≲18m$$ {7}^{\mathrm{m}}\lesssim {r}^{\prime },{i}^{\prime}\lesssim {18}^{\mathrm{m}} $$) from September ...

From Methane to Nanodiamond Precursors in Water: Superacid‐like Condensation Pathways Under Extreme Conditions

open access: yesAngewandte Chemie, Volume 138, Issue 3, 16 January 2026.
Under extreme pressure and temperature, superionic water acts as a strong superacid, catalyzing methane polycondensation through pentacoordinated carbonium ions (CH5+). This discovery reveals the non‐classical carbocation chemistry underlying the early stages of diamond formation in water under extreme conditions.

Modeling Atmospheric Lines by the Exoplanet Community (MALBEC) Version 1.0: A CUISINES Radiative Transfer Intercomparison Project

open access: yesThe Planetary Science Journal
Radiative transfer (RT) models are critical in the interpretation of exoplanetary spectra, in simulating exoplanet climates, and when designing the specifications of future flagship observatories.

Effects of Hydrogen on Fe‐S Alloys and Their Implications for the Martian Core

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract Meteorites suggest the Martian core comprises iron (Fe) or iron‐nickel (Fe‐Ni) alloy with sulfur (S) identified as the primary light element. The InSight data revealed a larger, less dense Martian core than previously estimated, indicating additional light elements.

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

open access: yesThe 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.

Random sampling technique for ultra-fast computations of molecular opacities for exoplanet atmospheres

open access: yes, 2017
Opacities of molecules in exoplanet atmospheres rely on increasingly detailed line-lists for these molecules. The line lists available today contain for many species up to several billions of lines.
