Poster title: Dust traps in the protoplanetary disk MWC 758: double vortex produced by two giant planets?

Poster abstract: Recent resolved observations of MWC 758 reveal two dust traps in its spiral-bearing circumstellar disk. 
The driving mechanism for this double structure is not yet identified.  We test a scenario were the observed asymmetries 
are induced by multiple giant planets using the 2D two-fluid (gas+dust) hydro code Dusty FARGO-ADSG.  Post-
processing radiative transfer allows us to make predictions for the dust thermal emission and compare our simulations 
with the current (sub)millimiter observations directly. 
We found that two 10 M_{Jup} planets, one orbiting at ∼20 AU (inner to the spiral structure) and another at ∼120 AU (outer 
to the spirals)  trigger and sustain two vortices via Rossby-wave instabilities.   The outer planet also drives multiple spiral 
arms in the gas, as it has previously been proposed.  These vortices trap the micron to mm dust, reproducing the double 
structure seen in the continuum. 
The inner and outer planets excite vortices at the outer and inner edges of their respective gaps. The inner planet was 
recently detected in the thermal infrared. Finding the kinematic signatures the outer planet would verify the proposed 
scenario.
