After 25 years of the prediction of the possibility of observations, and despite the many hundred of well studied transiting exoplanet systems, we are still waiting for the announcement of […]

Tidally Heated Exomoons Around ε Eridani b: Observability And Prospects For Characterization
Exomoons are expected to orbit gas giant exoplanets just as moons orbit solar system planets. Tidal heating is present in solar system satellites and it can heat up their interior […]

Stability and Detectability of Exomoons Orbiting HIP 41378 f, a Temperate Jovian Planet with an Anomalously Low Apparent Density
Moons orbiting exoplanets (“exomoons”) may hold clues about planet formation, migration, and habitability. We investigate the plausibility of exomoons orbiting the temperate (Teq=294 K) giant (R=9.2 R⊕) planet HIP 41378 […]

Habitable Moons Orbiting Free-Flying Planets
Liquid water is one of the most important conditions for the emergence of life as we know it on earth. Researchers from the ORIGINS cluster from the fields of astrophysics, […]

Detecting Exomoons From Radial Velocity Measurements Of Self-luminous Planets: Application To Observations Of HR 7672 B And Future Prospects
The detection of satellites around extrasolar planets, so called exomoons, remains a largely unexplored territory.

Microlensing Due To Free-Floating Moon-Planet Systems
Gravitational microlensing is a powerful method for detecting and characterizing free-floating planetary-mass objects (FFPs).

Tidal Heating of Exomoons In Resonance and Implications For Detection
The habitability of exoplanets can be strongly influenced by the presence of an exomoon, and in some cases the exomoon itself could be a possible place for life to develop. […]

On the Detection Of Exomoons Transiting Isolated Planetary-Mass Objects
All-sky imaging surveys have identified several dozen isolated planetary-mass objects (IPMOs), far away from any star. Here, we examine the prospects for detecting transiting moons around these objects. We expect […]

Exomoons In The Habitable Zones Of M Dwarfs
M dwarfs host most of the exoplanets in the local Milky Way. Some of these planets, ranging from sub-Earths to super-Jupiters, orbit in their stars’ habitable zones, although many likely […]

Exomoons May Be Home To Extraterrestrial Life
Moons orbiting planets outside our solar system could offer another clue about the pool of worlds that may be home to extra-terrestrial life, according to an astrophysicist at the University […]
