Habitable Zones around Main Sequence Stars

Icarus, 1993
A one-dimensional climate model is used to estimate the width of the habitable zone (HZ) around our Sun and around other main sequence stars. Our basic premise is that we are dealing with Earth-like planets with CO2/H2O/N2 atmospheres and that habitability requires the presence of liquid water on the planet's surface.

Habitable Zone Limits for Dry Planets

Astrobiology, 2011
Most 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

Expanding the Habitable Zone

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, 1998
Abstract 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.
