    "abstract": "This paper concerns the numerical approximation of the Euler equations for\nmulticomponent flows. A numerical method is proposed to reduce spurious\noscillations that classically occur around material interfaces. It is based on\nthe \"Explicit Simplified Interface Method\" (ESIM), previously developed in the\nlinear case of acoustics with stationary interfaces (2001, J. Comput. Phys.\n168, pp.~227-248). This technique amounts to a higher order extension of the\n\"Ghost Fluid Method\" introduced in Euler multicomponent flows (1999, J. Comput.\nPhys. 152, pp. 457-492). The ESIM is coupled to sophisticated shock-capturing\nschemes for time-marching, and to level-sets for tracking material interfaces.\nJump conditions satisfied by the exact solution and by its spatial derivative\nare incorporated in numerical schemes, ensuring a subcell resolution of\nmaterial interfaces inside the meshing. Numerical experiments show the\nefficiency of the method for rich-structured flows.",
