Precise Mass And Radius Determination For Two New And One Known Neptune-sized Planets Around G Dwarf Hosts
As part of the KESPRINT collaboration, we present the discovery and characterization of three exoplanets in the sub-Neptune to super-Neptune regime, spanning key regions of the exo-Neptunian landscape.

Detectability of Atmospheric Climate and Biosignatures with the Large Interferometer for Exoplanets (LIFE) for Terrestrial-type Exoplanets
We investigate the detectability of atmospheric biosignatures with the LIFE mission.
![Maps of average lensing parameters of simulated microlensing events due to different BFFPs over the 2D space log10[s(AU)]−log10[Mtot(M⊕)]. Here, Fi and Fw are fractions of simulated microlensing events due to BFFPs with intermediate and wide caustic topologies, respectively. ρ? shows the source radius projected on the lens plane and normalized to the Einstein radius, Lc is a length scale for caustic curves, ∆c represents the caustic area, τ is a time scale for microlensing events due to BFFPs, and P is the orbital period of binary lenses. -- Monthly Notices of the Royal Astronomical Society](https://i0.wp.com/astrobiology.com/wp-content/uploads/2025/10/On-the-Detection-of-Binary-Free-Floating-Planets.png?resize=1200%2C720&ssl=1)

On the Detection of Binary Free-Floating Planets in the Roman Galactic Exoplanet Survey
The recent discovery of 40 binary Jupiter-mass free-floating planets in the Trapezium cluster by the James Webb Space Telescope (Pearson & McCaughrean 2023) has opened new windows and questions in […]

Eccentric Orbits May Enhance The Habitability Of Earth-like Exoplanets
The detection and characterization of Earth-like planets around Sun-like stars is an important goal of exoplanetary research, given their promise for hosting potentially habitable conditions. Key orbital parameters, such as […]
