Modules for Experiments in Stellar Astrophysics (MESA): Planets, Oscillations, Rotation, and Massive Stars
Bill Paxton,Matteo Cantiello,Phil Arras,Lars Bildsten,Edward F. Brown,Aaron Dotter,Christopher R. Mankovich,Michael H. Montgomery,Dennis Stello,Francis Timmes,Richard H. D. Townsend +10 more
TL;DR: Modules for Experiments in Stellar Astrophysics (MESA) as discussed by the authors is an open source software package for modeling the evolution of stellar structures and composition. But it is not suitable for large-scale systems such as supernovae.

Modules for Experiments in Stellar Astrophysics (MESA): Giant Planets, Oscillations, Rotation, and Massive Stars
Bill Paxton,Matteo Cantiello,Phil Arras,Lars Bildsten,Edward F. Brown,Aaron Dotter,Christopher R. Mankovich,Michael H. Montgomery,Dennis Stello,Frank Timmes,Richard H. D. Townsend +10 more
TL;DR: The Modules for Experiments in Stellar Astrophysics (MESA) project as discussed by the authors provides a one-dimensional stellar evolution module, MESA Star, which can model the evolution of giant planets down to masses as low as one-tenth that of Jupiter.
Journal ArticleDOI
Magnetic field evolution in neutron star crusts due to the hall effect and ohmic decay
TL;DR: In this paper, the magnetic field evolution by the Hall effect and ohmic decay in the crust of neutron stars (NSs) has been studied and a detailed discussion of the boundary conditions at the solid-liquid interface is given.
Journal ArticleDOI
Saturation of the R mode instability
Phil Arras,Éanna É. Flanagan,Sharon M. Morsink,A. Katrin Schenk,Saul A. Teukolsky,Ira Wasserman +5 more
TL;DR: In this paper, the authors derived the saturation amplitude of stellar inertial oscillation modes in the WKB limit and analyzed their linear damping by bulk and shear viscosity, and the nonlinear coupling forces among these modes.
Journal ArticleDOI
Saturation of the R-mode Instability
Phil Arras,Éanna É. Flanagan,Sharon M. Morsink,A. Katrin Schenk,Saul A. Teukolsky,Ira Wasserman +5 more
TL;DR: In this paper, the saturation energy of stellar inertial oscillation modes in the WKB limit has been investigated and it has been shown that their saturation energy is extremely small, at least four orders of magnitude smaller than that found by previous investigators.
