Diving deep into rocky exoplanets [PDF]
, 2018 Approximately one-third of about four thousand known exoplanets are possibly rocky in nature. The chemical and physical diversity of rocky exoplanets is well beyond that of the rocky planets of our solar system; Mercury, Venus, Earth, and Mars.

Rapid Communications in Mass Spectrometry, Volume 40, Issue 19, 15 October 2026.ABSTRACT Rationale Nitrogen isotope values have been widely used for tracing ancient biogeochemical processes, but contaminant‐sensitive materials, such as Precambrian sedimentary rocks, meteorites, or returned extraterrestrial samples, often have low nitrogen levels and are thus vulnerable to modern organic contamination.

The Science of Exoplanets and Their Systems [PDF]
Astrobiology, 2013 A scientific forum on "The Future Science of Exoplanets and Their Systems," sponsored by Europlanet and the International Space Science Institute (ISSI) and co-organized by the Center for Space and Habitability (CSH) of the University of Bern, was held during December 5 and 6, 2012, in Bern, Switzerland.

A Solar Analog Model for Decrease in Far Ultraviolet Irradiance Under a Grand Minimum
Earth and Space Science, Volume 13, Issue 9, September 2026.Abstract Solar analog field stars having a range of magnetic activity can provide an estimate of solar spectral irradiance (SSI) variability relevant to understanding the Sun's influence on terrestrial climate. This approach is particularly useful for far ultraviolet (FUV) irradiance that cannot be observed from the Earth surface.

Acceleration in Exoplanet Magnetospheres
Symmetry, 2023 We briefly review the various acceleration mechanisms working in exoplanetary magnetospheres. The proposed scenarios are based on the investigation of planetary magnetospheres of the Solar System. Primary attention is paid to Earth and Jupiter, as the most characteristic examples of the various types of magnetospheric features determining different ...

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.Abstract The Earth's strongest natural radio emission is Auroral Kilometric Radiation (AKR), which is correlated with auroral intensity, and is a barometer for space weather. AKR is generated by the electron cyclotron maser instability, with sources on auroral field lines. Previous work on AKR and radio emissions from other planets (or stars) points to

Reflected Spectroscopy of Small Exoplanets II: Characterization of Terrestrial Exoplanets
The Astronomical Journal, 2022 Abstract A space telescope capable of high-contrast imaging has been recognized as the avenue toward finding terrestrial planets around nearby Sun-like stars and characterizing their potential habitability. It is thus essential to quantify the capability of reflected light spectroscopy obtained through direct imaging for terrestrial ...

Inferring Io's Internal Properties by Combining Gravity Measurements and Volcanic Activity
Journal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.Abstract With its extreme geological activity, Io represents an archetype for tidally heated exoplanets/moons and provides insight into early stages of terrestrial planet evolution. Decades of ground‐based observations and multiple space missions have refined our understanding of Io, yet it remains debated where inside Io the tidal heating takes place.
