EFFECT OF METALLICITY ON THE EVOLUTION OF THE HABITABLE ZONE OF LOW MASS STAR
Most stars have habitable zone. Habitable zones are areas in the solar system, or other star systems, which surround the parent star and allow for liquid water to exist.

| Summary: | Most stars have habitable zone. Habitable zones are areas in the solar system, or
other star systems, which surround the parent star and allow for liquid water to exist.
For a planet orbiting a parent star to have habitable zones, it must be at the right
distance. Low mass stars are the most studied because they live longer than high
mass stars. When low mass stars, such as the Sun, evolve, the location and time
scale of the habitable zone will also shift. In this final project we calculate the
evolution of low mass stars, using a stellar code program MESA, with various
metallicities to determine the location of the inner and outer boundaries of the
habitable zone. Metallicity has a very important role in the evolution of habitable
zones. The life of habitable zone of stars with higher metallicity are longer than
stars with lower metallicity.
