Resumen:
In this work, we displayed a new biological criterion that restricts the
traditional habitable zone. We set the internal boundary of this new UV
habitable zone from the maximum radiation that tolerates the DNA and its
external boundary from the levels of UV radiation needed in the
biogenesis processes. We also analyzed the evolution of the habitable
zones according to the variation of the stellar luminosity throughout
the main sequence stage. We evaluated these criteria in those planetary
stars that were observed by IUE satellite
