DESCRIPTION:Speakers: Richard Teague (Center for Astrophysics | Harvard & 
 Smithsonian)\nI will present a novel method to extract azimuthally average
 d 3D velocity profiles from ALMA data. Application of this to the well stu
 died source HD 163296 reveals a highly dynamical disk\, hosting large flow
  structures indicative of meridional flows likely driven by three embedded
  protoplanets. These flows provide an efficient transport mechanism of vol
 atile-rich gas in the disk atmosphere towards the planet-forming midplane.
  In addition\, we find tentative evidence of a slow disk wind in the outer
  100 au of the disk\, like connected to the previously detected large scal
 e wind described in Klaassen et al. (2013). I will further demonstrate how
  application of this method to multiple molecular species will allow us to
  map the dynamical structure of a protoplanetary disks in the (r\, z) plan
 e\, allowing us to directly search for characteristic flow structures whic
 h will help us to distinguish between potentially active instabilities. I 
 will end with an outlook to how extensions of these methods can be used to
  search for embedded planets by searching for localized deviations from th
 e background rotation.\n\nhttps://meetings.aip.de/event/1/contributions/15
