ABSTRACT octo-tiger is an astrophysics code to simulate the evolution of self-gravitating
and rotating systems of arbitrary geometry based on the fast multipole method, using …

We present a highly scalable demonstration of a portable asynchronous many-task
programming model and runtime system applied to a grid-based adaptive mesh refinement …

We present the results of an investigation of the dredge-up and mixing during the merger of
two white dwarfs (WDs) with different chemical compositions by conducting hydrodynamic …

We establish, in the framework of the theory of nested figures, the expressions for the
gravitational moments J 2 n of a systems made of homogeneous layers separated by …

We discuss the structure of differentially rotating, multilayer spheroids containing mass–
density jumps and rotational discontinuities at the interfaces. The study is based upon a …

We present a vectorial formalism to determine the approximate solutions to the problem of a
composite body made of homogeneous, rigidly rotating layers bounded by spheroidal …

We show that the two-dimensional structure of a rigidly rotating self-gravitating body is
accessible with relatively good precision by assuming a purely spheroidal stratification. With …

We report the existence of hydrostatic equilibrium states for a composite body made of two
rigidly rotating, homogeneous layers bounded by spheroidal surfaces, where the core has a …

We discuss the equilibrium conditions for a body made of two homogeneous components
separated by oblate spheroidal surfaces and in relative motion. While exact solutions are not …
