This paper presents a version of the HEXTOR energy balance model that has been configured for the study of habitable terrestrial planets orbiting low-mass stars. The model is validated for […]
TRAPPIST-1 is an ultra-cool dwarf that flares frequently. These flares shape the surrounding planets’ high-energy irradiation environments, with consequences for atmospheric chemistry and escape, and they can contaminate transmission spectroscopy […]
Explosive volcanic eruptions play a fundamental role in the evolution and observability of rocky exoplanets, serving as a key mechanism for injecting volatiles into planetary atmospheres and potentially modifying their […]
Following the 2022 alert of a TESS object of interest transiting TOI-5624 (a G7 V star ∼100 pc away), a CHEOPS campaign in 2023 detected four planetary signals at Pb≈3.4, […]
Red dwarf stars—cooler and smaller than our Sun—make up more than 75% of the stars in our Galaxy. Astronomers have shown that small, Earth-like planets are common around this type […]
Close-in terrestrial exoplanets around M dwarfs reside in dense, magnetized winds, where non-ideal plasma coupling can strongly affect how electromagnetic energy is redistributed within the dayside interaction region.
New observations are opening the possibility of characterising habitable environments in exoplanetary systems, with the recent example of the candidate hycean world K2-18 b.
More than 200 moons exist in our Solar System, yet no exomoon has been confirmed to date. While the innermost two planets of the Solar System lack natural satellites and […]
New Cornell research – co-authored by an undergraduate and two recent alumni – will help exoplanet scientists pinpoint the most likely places to look for life in the universe out […]
The concept of a system-wide measure of the sustainment of life (habitability) for space-faring interplanetary species is introduced and explored.
