Two Temperate Super-Earths Transiting A Nearby Late-type M Dwarf
In the age of JWST, temperate terrestrial exoplanets transiting nearby late-type M dwarfs provide unique opportunities for characterising their atmospheres, as well as searching for biosignature gases. We report here […]

Life On Exoplanets In The Habitable Zone Of M-Dwarfs?
Exoplanets orbiting in the habitable zone around M-dwarf stars have been prime targets in the search for life due to the long lifetimes of the host star, the prominence of […]

Assessing TESS's Yield of Rocky Planets Around Nearby M Dwarfs
Terrestrial planets are easier to detect around M dwarfs than other types of stars, making them promising for next-generation atmospheric characterization studies. The TESS mission has greatly increased the number […]

Assessing The Habitability of Planets Around Old Red Dwarfs
Planets orbiting close to the most abundant and longest-lasting stars in our Milky Way may be less hospitable to life than previously thought.

The High-Energy Radiation Environment Around a 10 Gyr M Dwarf: Habitable at Last?
High levels of X-ray and UV activity on young M dwarfs may drive rapid atmospheric escape on temperate, terrestrial planets orbiting within the liquid water habitable zone. However, secondary atmospheres […]

The Effect of Substellar Continent Size on Ocean Dynamics of Proxima Centauri b
The potential habitability of tidally locked planets orbiting M-dwarf stars has been widely investigated in recent work, typically with a non-dynamic ocean and without continents. On Earth, ocean dynamics are […]

Goldilocks Stars Are Best Places to Look for Life
In the search for life beyond Earth, astronomers look for planets in a star’s “habitable zone” — sometimes nicknamed the “Goldilocks zone” — where temperatures are just right for liquid […]
