Advancing Heliophysics and Space Weather Modeling Through Open Science

Space Weather, Volume 24, Issue 6, June 2026.
Abstract We present a community‐wide effort to develop a strategy and action plan to advance heliophysics and space weather modeling through open science. While open science has the potential to enhance the quality and pace of scientific discovery, its application to scientific modeling requires more careful consideration regarding open data and open ...

Search for an exosphere in sodium and calcium in the transmission spectrum of exoplanet 55 Cancri e [PDF]

, 2016
[Abridged] The aim of this work is to search for an absorption signal from exospheric sodium (Na) and singly ionized calcium (Ca$^+$) in the optical transmission spectrum of the hot rocky super-Earth 55 Cancri e.

Searching for helium in the exosphere of HD 209458b [PDF]

Astronomy & Astrophysics, 2003
Atmospheric models of the extrasolar, close-in giant planet HD 209458b predict strong absorption features from alkali metals (Seager & Sasselov 2000; Brown 2001). This was confirmed by the discovery of NaI by HST observations (Charbonneau et al. 2002). In this study we focus on the search for the helium absorption feature at 10 830 A, also predicted to

Potential relations between Caloris basin and Mercury's sodium exosphere [PDF]

, 2006
We have developed a 1D thermal model of Mercury's regolith, in order to simulate the heat diffusion in the upper subsurface (first 10 m). We assume in our model that the thermophysical properties of the Hermean regolith are similar to those of the lunar ...

What Observations Would an Energetic Neutral Atom Imager Have Made During the Voyager 2 Flyby of Uranus?

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract We present large‐scale simulations of energetic neutral atom (ENA) emissions at Uranus from a spacecraft viewpoint. Models of magnetic field, extended hydrogen exosphere, moon‐sourced neutral tori, and proton radiation belt are implemented into a simulator to evaluate the production of ENAs for L $L$ = 1–15.

Titans exosphere and its interaction with Saturns magnetosphere [PDF]

, 2008
Titan's nitrogen-rich atmosphere is directly bombarded by energetic ions, due to its lack of a significant intrinsic magnetic field. Singly charged energetic ions from Saturn's magnetosphere undergo charge-exchange collisions with neutral atoms in Titan ...

An Estimate of the Importance of Electron-stimulated Desorption of Sodium at Mercury

The Planetary Science Journal
We revisit the importance of electron-stimulated Desorption (ESD) as a source of neutral sodium (Na) atoms and Na ^+ ions in Mercury’s exosphere and ionosphere.

Temporal Variability of Saturn's H2 Dayglow and Northern Aurora Observed by Hisaki and Cassini

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract Ultraviolet (UV) emissions from molecular hydrogen in Saturn's atmosphere consist of bright auroral emission over the poles and disk‐wide airglow. The dayside disk emits substantial intensities (dayglow) previously detected by various instruments.

The first analysis of the outward H fluxes measured by IBEX-Lo in 20–50 RE geocentric distances

Frontiers in Astronomy and Space Sciences
In this study, we analyze the energetic neutral atom (ENA) observations measured in the lowest energy channel (10–21 eV) of the IBEX-Lo instrument on Interstellar Boundary Explorer (IBEX) during two spring seasons, day of year (DOY) 101–146, 2009, and ...
