Simulated Performance of Energy-resolving Detectors Towards Exoplanet Imaging with the Habitable Worlds Observatory
One of the primary science goals of the Habitable Worlds Observatory (HWO) as defined by the Astro2020 decadal survey is the imaging of the first Earth-like planet around a Sun-like […]

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 […]

Comparing NASA Discovery and New Frontiers Class Mission Concepts for the Io Volcano Observer (IVO)
Jupiter’s moon Io is a highly compelling target for future exploration that offers critical insight into tidal dissipation processes and the geology of high heat flux worlds, including primitive planetary […]
![The population of transiting exoplanets and brown dwarfs, as obtained from TEPCat [6], marker size corresponds to equilibrium temperature. Targets being observed in Cycle 1 and/or 2 are highlighted accordingly, their temperature is further indicated by their color, and the histogram shows the number of targets as a function of mass. The red line indicates the lowest mass objects being characterized through direct techniques to date. -- astro-ph.IM](https://i0.wp.com/astrobiology.com/wp-content/uploads/2024/08/The-Unrealised-Interdisciplinary.png?resize=1200%2C721&ssl=1)

The Unrealised Interdisciplinary Advantage of Observing High Mass Transiting Exoplanets and Brown Dwarfs — Strategic Exoplanet Initiatives with HST and JWST White Paper
We advocate for further prioritisation of atmospheric characterisation observations of high mass transiting exoplanets and brown dwarfs.

Investing in the Unrivaled Potential of Wide-Separation Sub-Jupiter Exoplanet Detection and Characterisation with JWST — Strategic Exoplanet Initiatives with HST and JWST White Paper
We advocate for a large scale imaging survey of nearby young moving groups and star-forming regions to directly detect exoplanets over an unexplored range of masses, ages and orbits. Discovered […]

Do SETI Optimists Have a Fine-Tuning Problem?
In ecological systems, be it a garden or a galaxy, populations evolve from some initial value (say zero) up to a steady state equilibrium, when the mean number of births […]
