Habitable Planets with High Obliquities
Icarus, 1997Earth's obliquity would vary chaotically from 0 degrees to 85 degrees were it not for the presence of the Moon (J. Laskar, F. Joutel, and P. Robutel, 1993, Nature 361, 615-617). The Moon itself is thought to be an accident of accretion, formed by a glancing blow from a Mars-sized planetesimal.

Habitable Planet, Characterization
2011The spectrum of a planet can contain signatures of atmospheric species, which create its spectral fingerprint. The presence and abundance of atmospheric species, in the context of the properties of the star and the planet, can elucidate the underlying physics and characterize a planetary environment.

Evolution of a Habitable Planet
Annual Review of Astronomy and Astrophysics, 2003▪ 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.

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.

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

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 ...

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 ...
