SUMMARY:Some questions and answers from protoplanetary disk observations: 
 machine learning\, hidden rings\, and fake vortices - Alvaro Ribas (IOA Ca
 mbridge)

CONTACT:Thomas Jannaud
DESCRIPTION:In this talk\, I will discuss some results from different obse
 rvations of protoplanetary disks. I will first present our work combining 
 disk models with artificial neural networks to model observed SEDs using a
  statistical approach\, and what we learned by applying this to disks in T
 aurus. I will then discuss our surprising findings when studying the nearb
 y protoplanetary disk MP Mus with ALMA\, one of the best young solar analo
 gues which remained relatively unexplored until recently. Finally\, I will
  propose an alternative (and simpler) explanation for some of the disk azi
 muthal asymmetries that ALMA has revealed\, explain how we can use this to
  gain information about the vertical structure of disks\, and provide evid
 ence for at least a number of these asymmetries likely having a geometric 
 origin.
