Detection of lithium in the exosphere of Mercury [PDF]
Nature CommunicationsMercury’s exosphere contains various neutral species, including hydrogen, helium, sodium, potassium, calcium, magnesium, aluminum, iron, and manganese. Although lithium has been predicted to exist, it had not been detected until now. Here, we demonstrate

A transient enhancement of Mercury’s exosphere at extremely high altitudes inferred from pickup ions [PDF]
Nature Communications, 2020 Mercury has a global dayside exosphere that is very tenuous and does not extend far from the planet. Here, the authors show enhancement of neutral densities at high altitudes inferred from pickup ions that is most likely caused by the impact of a ...

The Influence of Surface Binding Energy on Sputtering in Models of the Sodium Exosphere of Mercury
The Planetary Science Journal, 2022 We have simulated the sodium (Na) exosphere of Mercury to show how the exosphere is affected by the assumed surface binding energy (SBE) of Na in the sputtered component.

Atomic Simulations of Volatile Coverage on Silicate Surfaces
Geophysical Research LettersUnderstanding how surface processes shape exosphere formation on airless bodies is limited by how surface properties influence the ejection of volatiles such as Na.

The relation between the surface composition anomaly and distribution of the exosphere of Mercury
Earth, Planets and Space, 2023 In celestial bodies with tenuous collisionless atmospheres, such as Mercury, the spatial distribution of the exosphere is expected to reflect the surface composition.

Terrestrial exospheric hydrogen density distributions under solar minimum and solar maximum conditions observed by the TWINS stereo mission [PDF]
Annales Geophysicae, 2015 Circumterrestrial Lyman-α column brightness observations above 3 Earth radii (Re) have been used to derive separate 3-D neutral hydrogen density models of the Earth's exosphere for solar minimum (2008, 2010) and near-solar-maximum (2012) conditions ...
