Title: High Resolution Shock-Capturing Hydrodynamic
Scheme for Astrophysical Flows
Authors: Yu Cong
Topic: 2 
Session: poster 

Abstract: 
Many problems at the forefront of
theoretical astrophysics require the treatment of
dynamical fluid behavior. We present an efficient
high resolution shock-capturing hydrodynamics scheme
designed to study astrophysical dynamcial phenomena.
We have implemented weighted essentially
non-oscillatory (WENO) scheme to gain fifth order
accuracy in space. HLLE approximate Riemann solver is
implemented for flux computation at cell interface.
For time integration we apply a third order total
variation diminishing (TVD) Runge-Kutta scheme.
Examples of  jets propagation and binary accretion are
presented demonstrating the ability of the scheme to
address challenging open questions in astrophysics. We
also investigate the well know Papaloizou-Pringle
slender torus instability by our new code.
