DESCRIPTION:Brown dwarfs are often described as failed stars\, however the
  flip side of this description is that they can also be described as over-
 ambitious planets. With masses between 13-70 Jupiter masses they have cool
  atmospheres dominated by cloud features\, molecules and show features due
  to weather.  These atmospheres have a lot of similarities with atmospher
 es we see in planets in our solar system\, and also directly imaged exopla
 nets.  The question then is: How like hot Jupiters are irradiated brown d
 warfs? \n\nIn this seminar I will describe the known irradiated brown dwa
 rfs and how they evolve into post-common envelope systems containing a whi
 te dwarf. These rare binaries have very short periods (~hrs) and the brown
  dwarf is irradiated by the white dwarf companion\, often with large amoun
 ts of UV radiation. I will discuss the atmospheres of these highly irradia
 ted brown dwarfs and their similarities with irradiated exoplanets.
