Query: UV Surface Environments and Atmospheres of Earth-like Planets Orbiting
  White Dwarfs   An Earth-like exoplanet orbiting a white dwarf would be exposed to different
UV environments than Earth, influencing both its atmospheric photochemistry and
UV surface environment. Using a coupled 1D climate-photochemistry code we model
atmospheres of Earth-like planets in the habitable zone of white dwarfs for
surface temperatures between 6000 K and 4000 K, corresponding to about 7
billion years of white dwarf evolution, as well as discuss the evolution of
planetary models in the habitable zone during that evolution.
