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. Here we show that "land planets" (desert worlds with limited surface water) have wider habitable zones than ...

Moon formation and habitability in the circumplanetary habitable zone
2022<p>We investigate the efficiency of moon formation around giant planets with numerical N-body simulations and study the habitability of Earth-sized, newly formed moons. Our results show that by the end of the moon formation process the individual mass of moons is higher, if the planet is in a close orbit around the host star. We also find

Science, 1999
PLANETARY SYSTEMSNew finds on Earth, such as colonies of bacteria deep underground, have suggested that organisms can thrive even if sealed off from the sun, by living on chemical rather than solar energy. Therefore the possible environments for life in space, once restricted to the relatively narrow slice of the solar system inside the martian orbit ...

Circumstellar habitable zones: an overview
Acta Astronautica, 1998Abstract We review aspects of circumstellar habitable zones based on results reported at the First International Conference on Circumstellar Habitable Zones (held in 1994 at NASA Ames Research Center). Recent advances in atmospheric radiative transfer modeling have shown that circumstellar habitable zones are wider than previously thought.

We propose the concept of a "Galactic Habitable Zone" (GHZ). Similar to the circumstellar habitable zone (CHZ), the GHZ is that region in a spiral galaxy where life can exist. The width of the GHZ is controlled by two factors. The inner (closest to the center of the galaxy) limit is set by threats to complex life: nearby transient sources of ionizing ...

The Habitable Zone: Basic Concepts
2013The detection of exoplanets has undergone extraordinary growth over the past couple of decades since substellar companions were detected around HD 114762 (Latham et al., 9 1992, and 51 Peg (Mayor and Queloz, 1995. From there, the field rapidly expanded from the exclusivity of exoplanet detection to include exoplanet characterization.
