Magnetohydrodynamic turbulence in a strongly magnetised plasma
S. Sridhar
I present a review of incompressible magnetohydrodynamic (MHD) turbulence in a strongly magnetised plasma. The approach is phenomenological even where a more rigorous theory is ava…
Slow m=1 instabilities of softened gravity Keplerian discs
S. Sridhar, Tarun Deep Saini
We present the simplest model that permits a largely analytical exploration of the m=1 counter-rotating instability in a "hot" nearly Keplerian disc of collisionless self-gravitati…
The shear dynamo problem for small magnetic Reynolds numbers
S. Sridhar, Nishant K. Singh
We study large-scale dynamo action due to turbulence in the presence of a linear shear flow, in the low conductivity limit. Our treatment is nonperturbative in the shear strength a…
Nonperturbative quasilinear approach to the shear dynamo problem
S. Sridhar, Kandaswamy Subramanian
We study large-scale dynamo action due to turbulence in the presence of a linear shear flow. Our treatment is quasilinear and equivalent to the standard `first order smoothing appr…
Slow pressure modes in thin accretion discs
Tarun Deep Saini, Mamta Gulati, S. Sridhar
Thin accretion discs around massive compact objects can support slow pressure modes of oscillations in the linear regime that have azimuthal wavenumber . We consider finite, f…
