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 atmosphere
 s we see in planets in our solar system\, and also directly imaged exoplan
 ets.  The question then is: How like hot Jupiters are irradiated brown dwa
 rfs? \nIn this seminar I will describe the known irradiated brown dwarfs a
 nd how they evolve into post-common envelope systems containing a white dw
 arf. These rare binaries have very short periods (~hrs) and the brown dwar
 f is irradiated by the white dwarf companion\, often with large amounts of
  UV radiation. I will discuss the atmospheres of these highly irradiated b
 rown dwarfs and their similarities with irradiated exoplanets.\n
