HD 35843: A Sun-like Star Hosting A Long Period Sub-Neptune And Inner Super-Earth
We report the discovery and confirmation of two planets orbiting the metal-poor Sun-like star, HD 35843 (TOI 4189). HD 35843 c is a temperate sub-Neptune transiting planet with an orbital […]

Superhabitable Planets Around Mid-Type K Dwarf Stars Enhance Simulated JWST Observability and Surface Habitability
In our search for life beyond the Solar System, certain planetary bodies may be more conducive to life than Earth. However, the observability of these `superhabitable’ planets in the habitable […]

Evolution Of Steam Worlds: Energetic Aspects
Sub-Neptunes occupy an intriguing region of planetary mass-radius space, where theoretical models of interior structure predict that they could be water-rich, where water is in steam and supercritical state.

Unveiling Habitable Planets: Toy Coronagraph Tackles The Exozodiacal Dust Challenge
Directly imaging Earth-like exoplanets within habitable zones is challenging because faint signals can be obscured by exozodiacal dust, analogous to our solar system’s zodiacal dust. This dust scatters starlight, creating […]
