Exoplanet Research with the Stratospheric Observatory for Infrared Astronomy (SOFIA)

open access: yes, 2017
When the Stratospheric Observatory for Infrared Astronomy (SOFIA) was conceived and its first science cases defined, exoplanets had not been detected. Later studies, however, showed that optical and near-infrared photometric and spectrophotometric follow-

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 ...

Photochemical Hazes Dramatically Alter Temperature Structure and Atmospheric Circulation in 3D Simulations of Hot Jupiters

open access: yesThe Astrophysical Journal, 2023
Photochemical hazes are expected to form in hot Jupiter atmospheres and may explain the strong scattering slopes and muted spectral features observed in the transmission spectra of many hot Jupiters.

Spatially resolved spectroscopy across stellar surfaces. I. Using exoplanet transits to analyze 3-D stellar atmospheres

open access: yes, 2017
CONTEXT: High-precision stellar analyses require hydrodynamic modeling to interpret chemical abundances or oscillation modes. Exoplanet atmosphere studies require stellar background spectra to be known along the transit path while detection of Earth ...

Atmospheric Circulation of Terrestrial Exoplanets [PDF]

open access: yes, 2013
The investigation of planets around other stars began with the study of gas giants, but is now extending to the discovery and characterization of super-Earths and terrestrial planets.

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.

The barycentric motion of exoplanet host stars: tests of solar spin-orbit coupling

open access: yes, 2010
Empirical evidence suggests a tantalising but unproven link between various indicators of solar activity and the barycentric motion of the Sun. The latter is exemplified by transitions between regular and more disordered motion modulated by the motions ...

Magnetic Evolution of Super‐Earth Exoplanets With a Basal Magma Ocean

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract Habitability of super‐Earths likely requires self‐sustained magnetic fields to shield their atmospheres from stellar forcing. Extreme pressures and temperatures probably produce a long‐lived basal magma ocean (BMO), a potential source for these fields.

JWST Discovers the Vertical Structure of Uranus' Ionosphere

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract On 19 January 2025, the James Webb Space Telescope (JWST) program # $\mathrm{\#}$5073 observed Uranus for almost a full rotation with NIRSpec. We present the first ever vertical ionospheric profiles of H3+ ${\mathrm{H}}_{3}^{+}$ temperature, volumetric density and total emission.
