by G. Gonzalez, D. Brownlee, P. Ward
Publisher: arXiv 2001
Number of pages: 57
Description:
The Galactic Habitable Zone (GHZ) is that region in the Milky Way where an Earth-like planet can retain liquid water on its surface and provide a long-term habitat for animal-like aerobic life. In this paper we examine the dependence of the GHZ on Galactic chemical evolution.
