Abstract;

In this work we studied the evolution of the habitable zone depending on the evolution of the host star. We notice it drastically changes on the phases of the life of the star. One important factor of the distance of the habitable zone is the albedo of the planet. This albedo is different depending on the wavelength and surface. We compared the snow and metal-rich albedos and their effect reflecting the UV radiation. To improve our model, it was compared with realistic white dwarf spectra, obtaining similar results. Finally, it was compared the difference of using simulations such as SSE and MESA.
