In the coming years and decades, advanced space-and ground-based observatories will
allow an unprecedented opportunity to probe the atmospheres and surfaces of potentially …

The prospects for the habitability of M-dwarf planets have long been debated, due to key
differences between the unique stellar and planetary environments around these low-mass …

The NASA Kepler mission ha s discovered thousands of new planetary candidates, many of
which have been confirmed through follow-up observations. A primary goal of the mission is …

A planetary atmosphere is the outer gas layer of a planet. Besides its scientific significance
among the first and most accessible planetary layers observed from space, it is closely …

Conventional definitions of habitability require abundant liquid surface water to exist
continuously over geologic timescales. Water in each of its thermodynamic phases interacts …

Context. Planets orbiting low-mass stars such as M dwarfs are now considered a
cornerstone in the search for planets with the potential to harbour life. GJ 273 is a planetary …

The prerequisites and ingredients for life seem to be abundantly available in the Universe.
However, the Universe does not seem to be teeming with life. The most common …

The habitable zone (HZ) is commonly defined as the range of distances from a host star
within which liquid water, a key requirement for life, may exist on a planet's surface …

Habitability is a measure of an environment's potential to support life, and for exoplanets this
is tied to the presence of surface liquid water. Whether or not an exoplanet is able to …

The discovery of planets orbiting stars other than the Sun has accelerated over the past
decade, and this trend will continue as new space-and ground-based observatories employ …
