DESCRIPTION:Recent observations of protoplanetary discs have shown clear ev
 idence of warps and misalignments\, where the disc is best described with 
 an orientation that changes as a function of the distance from the central
  star. A number of scenarios have been proposed to explain the origins of 
 these misalignments\, including the presence of a hidden companion on an o
 rbit that is misaligned with respect to the outermost disc. By introducing
  such a misaligned body we need to consider the potential of disc precessi
 on\, inclination damping and alignment time-scales. I will show how an und
 erstanding of these effects can allow us to infer what is happening in the
 se systems with observed misalignments and the implications for their long
  term evolution. This tour will include applications to TW Hya (a rapidly 
 moving shadow)\, misalignments induced by a flyby\, HH30 (with a wiggling 
 jet) and HD100453 (with a strongly misaligned inner disc). https://astrono
