Characterizing the atmospheres of extrasolar planets is the new frontier in exoplanetary
science. The last two decades of exoplanet discoveries have revealed that exoplanets are …

Abstract The Cassini Ultraviolet Imaging Spectrograph (UVIS) is part of the remote sensing
payload of the Cassini orbiter spacecraft. UVIS has two spectrographic channels that …

We present a one-dimensional coupled ion-neutral photochemical kinetics and diffusion
model to study the atmospheric composition of Titan in light of new theoretical kinetics …

We have developed a one-dimensional photochemical and thermochemical kinetics and
diffusion model to study the effects of disequilibrium chemistry on the atmospheric …

Motivated by recent spectroscopic evidence for carbon-rich atmospheres on some transiting
exoplanets, we investigate the influence of the C/O ratio on the chemistry, composition, and …

We report on the physical and chemical aeronomy of the hot Jupiter HD 209458b, a
prominent case in the growing sample of known extrasolar planets. Our work is motivated by …

A global-mean model of coupled neutral and ion chemistry on Titan has been developed.
Unlike the previous coupled models, the model involves ambipolar diffusion and escape of …

Thermal structure of the atmosphere of Jupiter was measured from 1029 km above to 133
km below the 1‐bar level during entry and descent of the Galileo probe. The data confirm the …

In the context of recent observations, microphysical models, and laboratory data, a
photochemical model of Titan's atmosphere, including updated chemistry focusing on rate …

In this work we investigate the impact of calculating non-equilibrium chemical abundances
consistently with the temperature structure for the atmospheres of highly-irradiated, close-in …
