We demonstrate that rapidly rotating bipolytropic (composite polytropic) stars and toroidal disks can be obtained using Hachisu's self consistent field technique. The core and the envelope in such a structure can have different polytropic indices and also different average molecular weights. The models converge for high $T/|W|$ cases, where T is the kinetic energy and W is the gravitational energy of the system. The agreement between our numerical solutions with known analytical as well as… Expand
The equilibrium of overpressurized polytropes
We investigate the impact of an external pressure on the structure of self-gravitating polytropes for axially symmetric ellipsoids and rings. The confinement of the fluid by photons is accounted forExpand

Polytropes have long been used to model a wide variety of astrophysical objects. A bipolytrope (composite polytrope) may be used for bodies with a distinct core-envelope structure. In this shortExpand
Is Betelgeuse the Outcome of a Past Merger?
We explore the possibility that the star alpha Orionis (Betelgeuse) is the outcome of a merger that occurred in a low mass ratio (q = M2/M1 = 0.07 - 0.25) binary system some time in the past hundredsExpand

Accelerating Octo-Tiger: Stellar Mergers on Intel Knights Landing with HPX
TLDR
This paper studies the node-level performance of Octo-Tiger's fast multipole method, and achieves up to 408 GFLOPS, resulting in a speedup of 2x compared to a 24-core Skylake-SP platform, using the same high-level abstractions. Expand
