Definition

In a binary star system, a planet may in principle exist either in an orbit around a star or in an orbit that surrounds both stars in the system; in the former case, we refer to it as a circumprimary planet. To calculate the boundaries of the habitable zone (HZ) around a star of a binary star system (circumprimary orbits), it is assumed that the HZ is an annulus around the star where an Earth-like planet (with similar atmospheric composition to that of Earth) and a sufficient amount of water can permanently maintain liquid water on its solid surface.

Basic Methodology

The locations of the boundaries of the HZ, and therefore the capability of the planet in maintaining conditions for habitability, depend on the total flux received at the top of its atmosphere. Since the atmosphere converts stellar insolation to temperature structure and surface temperature of a planet, its interaction with the stellar radiation plays an important role in considering whether a planet can...
