Habitable Zone Limits for Dry Planets
Astrobiology, 2011Most discussion of habitable planets has focused on Earth-like planets with globally abundant liquid water. For an “aqua planet” like Earth, the surface freezes if far from its sun, and the water vapor greenhouse effect runs away if too close.

Host Star Evolution for Planet Habitability
Origins of Life and Evolution of Biospheres, 2016With about 2000 exoplanets discovered within a large range of different configurations of distance from the star, size, mass, and atmospheric conditions, the concept of habitability cannot rely only on the stellar effective temperature anymore. In addition to the natural evolution of habitability with the intrinsic stellar parameters, tidal, magnetic ...

SPIE Proceedings, 2012
A notional space telescope configuration is presented that addresses issues of angular resolution, spectral bandwidth and rejection of host star glare by means of a double dispersion architecture. The telescope resolves angle by wavelength. In an earlier embodiment for surveys, a primary objective grating telescope architecture was shown to acquire ...

Evolution of a habitable planet
Geochimica et Cosmochimica Acta, 2006■ Abstract Giant planets have now been discovered around other stars, and it is only a matter of time until Earth-sized planets are detected. Whether any of these planets are suitable for life depends on their volatile abundances, especially water, and on their climates. Only planets within the liquid-water habitable zone (HZ) can support life on their

Habitability of Planets and Moons
2018The author takes us to visit Saturn’s moon Titan, and Venus, Mars, and to the unconfirmed planet GJ581d. Although we find unearthly conditions on these bodies’ surfaces today, things were different in the past. Even now, there are oceans deep below Titan’s frozen ice shell that itself sees liquid methane rains and vast ethane-filled lakes.

Detection of Habitable Planets and the Search for Life
2013One of the main scientific drivers for extrasolar planet research is the search for terrestrial planets in the habitable zone (HZ) and subsequently the detection of biosignatures indicating the presence of life. This goal is of fundamental importance to answer the question whether the Solar System is the only place in our universe that developed life ...
