Irradiation effects in close white dwarf + brown dwarf binaries.

Post common-envelope white dwarf+ brown dwarf binary systems are rare, with only a handful known to date. In at least two of these systems we detect photometric variations that are indicative of irradiation of the brown dwarf by its much hotter companion.

I will discuss the likely effect of the irradiation on the brown dwarf's atmosphere and explain how we can use these systems to understand processes within irradiataed exoplanet atmospheres.
