Ultraviolet radiation constraints around the circumstellar habitable zones

Ultraviolet radiation is known to inhibit photosynthesis, induce DNA destruction and cause damage to a wide variety of proteins and lipids. In particular, UV radiation between 200 and 300 nm becomes energetically very damaging to most of the terrestrial biological systems. On the other hand, UV radi...

description Ultraviolet radiation is known to inhibit photosynthesis, induce DNA destruction and cause damage to a wide variety of proteins and lipids.

In this work, we use these properties of the UV radiation to define the boundaries of an ultraviolet habitable zone.
