Active Moons In Our Solar System And Beyond — Io, Europa, Enceladus, Triton, and Exomoons
The outgassing signatures of Io, Europa, Enceladus, Triton, and Io-like exomoons are the focus of this review chapter. The rocky volcanic world of Io is unique in our Solar System, […]

The JWST Search For Earth-Luna Analogs: Upper Limits On Exomoons And Refined Ephemerides For TOI 700 d And e
While no conclusive detections of exomoons have been reported to date, planet formation theories predict that satellites should be a common outcome of the collisional dynamics in early extrasolar systems.

The Influence Of Hypothetical Exomoons On Planetary Thermal Phase Curves
More than 200 moons exist in our Solar System, yet no exomoon has been confirmed to date. While the innermost two planets of the Solar System lack natural satellites and […]

Habitability Of Tidally Heated H2-Dominated Exomoons Around Free-Floating Planets
Exomoons around free-floating planets (FFPs) can survive their host planet’s ejection. Such ejections can increase their orbital eccentricity, providing significant tidal heating in the absence of any stellar energy source.

Finding Endor With Lunar Eclipses — Exomoons And Exorings With The Habitable Worlds Observatory II
Giant planets in the habitable zone may host exomoons with conditions conducive to life. In this paper we describe a method by which the Habitable Worlds Observatory (HWO) could detect […]
