The Role Of Atmospheric Composition In Defining The Habitable Zone Limits And Supporting E. coli Growth
Studying exoplanet atmospheres is essential for assessing their potential to host liquid water and their capacity to support life (their habitability).

An Origin For Pluto’s Subsurface Ocean?
Billions of years ago, in the frigid outer reaches of our solar system, two icy worlds collided. Rather than destroying each other in a cosmic catastrophe, they spun together like […]

Water-Bearing Objects in the Core of the Rho Ophiuchi Cloud Complex
We present a study of very low-mass stars and brown dwarfs in the rich star-forming core of the Rho Ophiuchi cloud complex. The selection of the sample relies on detecting […]

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.
