Differential rotation and hydrodynamic stability of hot neutron stars [PDF]
Astronomy and Astrophysics, 2003 Young neutron stars formed in core collapse or originating in the merger of a binary neutron star system may possess significant differential rotation. We consider the stability properties of such hot (non-superfluid) differentially rotating neutron stars.

Mechanical Stabilization of Magneto-Gravitational Instability in Rotating Viscoelastic Media through a Second Order Generalized Hydrodynamic Framework [PDF]
EPJ Web of ConferencesA theoretical study of magneto-gravitational instability of a rotating, finitely conducting viscoelastic substance is presented in this paper by a second-order generalized hydrodynamic (GH) system.

Astrophysical Journal, 2001 We examine the global, hydrodynamic stability of solar latitudinal differential rotation in a "shallow-water" model of the tachocline. Charbonneau, Dikpati, & Gilman have recently shown that two-dimensional disturbances are stable in the tachocline (which contains a pole-to-equator differential rotation s < 18%). In our model, the upper boundary of the

Viscous Stability Criterion for Hydrodynamic Differential Rotation
INTERNATIONAL JOURNAL OF COMPUTERS & TECHNOLOGY, 2023 Viscous stability criterion in a thin layer on a rotating sphere is studied. The case when the fluid is inviscid was explained by Watson in 1981, the work was motivated by the idea suggested by Drazin and Ried in their celebrated text "Hydrodynamic Stability"; here we will investigate the model worked out by B. Sherif and C.

On the hydrodynamic stability of an imploding rotating circular cylindrical liquid liner [PDF]
Fluid Dynamics Research, 2020 Abstract The hydrodynamic stability of an imploding cylindrical liquid liner is analytically and numerically investigated. Such dynamic system can be used to compress gas trapped by the liner, as one may seek in a hydrogen fusion reactor.
