SUMMARY:Vorticies from low-mass planet formation in &quot\;transition disc

DESCRIPTION:I will describe how so-called "transition discs" are natural s
 ites for the trapping of pebble-sized dust particles. Consequently these p
 ebble traps are natural sites for pebble accretion. I will argue that rapi
 d pebble accretion can lead to the disc becoming locally baroclinic and pr
 one to the formation of anti-cyclonic vorticies. I will then sketch out an
  evolutionary cycle of vortex formation and destruction and relate this me
 chanism to the observed asymmetries in "transition discs".
