High-Resolution Spectra For A Wide Range of Habitable Zone Planets Around Sun-like Stars
The search for life in the universe is currently focused on Earth-analog planets. However, we should be prepared to find a diversity of terrestrial exoplanets not only in terms of […]

Small Sensitivity of the Simulated Climate of Tidally Locked Aquaplanets to Model Resolution
Tidally locked terrestrial planets around low-mass stars are the prime targets of finding potentially habitable exoplanets. Several atmospheric general circulation models have been employed to simulate their possible climates, however, […]

Is The Faint Young Sun Problem For Earth Solved?
Stellar evolution models predict that the solar luminosity was lower in the past, typically 20-25 % lower during the Archean (3.8-2.5 Ga). Despite the fainter Sun, there is strong evidence […]

Earth-Size, Habitable Zone Planet Found Hidden in Early NASA Kepler Data
A team of transatlantic scientists, using reanalyzed data from NASA’s Kepler space telescope, has discovered an Earth-size exoplanet orbiting in its star’s habitable zone, the area around a star where […]

Dead Zones of Classical Habitability in Stellar Binary Systems
Although habitability, defined as the general possibility of hosting life, is expected to occur under a broad range of conditions, the standard scenario to allow for habitable environments is often […]
