Next Tuesday (8-13-13), 10 AM, please join the Department of Astronomy in  
 Phillips for a presentation by graduate student, Diego Munoz, entitled:  
   
 "Modeling and Simulation of Circumstellar Disks with the Next Generation of Hydrodynamic Solvers"  
   
 **Abstract**  
   
 Although the theory of planet formation is still incomplete, there is  
 unanimous consensus that planets form in circumstellar disks of gas and  
 dust. However, even though many (if not most) stars form in binaries, the  
 effects of stellar multiples on circumstellar disk evolution remain  
 relatively unexplored. The lack of symmetry, importance of tidal  
 perturbations, fully three-dimensional configurations, and supersonic  
 velocities in young multiple stellar systems demand modeling by direct  
 numerical simulation. However, the results can depend greatly on the  
 numerical method employed.

In this thesis talk, I will describe the applications of the novel  
 moving-mesh code AREPO to problems of circumstellar disks with geometric  
 configurations that present important computational challenges to  
 conventional hydrodynamic solvers. These problems include planet-disk,  
 star-disk and disk-disk interactions. I will explain the moving-mesh  
 approach, discuss the importance of numerical simulations in modern  
 astrophysics, and review the increased attention codes are receiving as  
 objects of study. I will discuss the modeling of circumstellar disks in  
 AREPO, starting with two-dimensional, isolated systems,and ending with  
 fully three-dimensional, self-gravitating thin disks in configurations with  
 more than one star.
