The stability of accretion tori - I . Long - wavelength modes of slender tori
We elucidate the inviscid instabilities of an isentropic torus found previously by Papaloizou & Pringle. The torus is a polytrope of index, n, and has a small ratio of minor radius, a, to orbital radius, r0 • In equilibrium it rotates on cylinders with angular velocity profile O,ocr-q. Linear modes are proportional to exp i (m¢-wt). For small P=ma/r0 , we justify the use of height-averaged equa...
متن کاملOscillation modes of relativistic slender tori
Accretion flows with pressure gradients permit the existence of standing waves which may be responsible for observed quasi-periodic oscillations (QPO’s) in X-ray binaries. We present a comprehensive treatment of the linear modes of a hydrodynamic, nonself-gravitating, polytropic slender torus, with arbitrary specific angular momentum distribution, orbiting in an arbitrary axisymmetric spacetime...
متن کاملWeak nonlinear coupling between epicyclic modes in slender tori
We examine nonlinear oscillations of slender tori in the vicinity of black holes and compact stars. These tori represent useful probes of the complicated, nonlinear dynamics of real accretion disks and provide at least qualitative understanding of their oscillations. We demonstrate that epicyclic modes of such tori are weakly coupled due to the pressure and gravitational forces. We explore all ...
متن کاملGlobal Magnetohydrodynamical Simulations of Accretion Tori
Global time-dependent simulations provide a means to investigate timedependent dynamic evolution in accretion disks. This paper seeks to extend previous local simulations by beginning a systematic effort to develop fully global three-dimensional simulations. The nonlinear development of the magnetorotational instability is investigated using a time-explicit finite difference code written in cyl...
متن کاملSuperexponential Stability of Kam Tori
We study the dynamics in the neighbourhood of an invariant torus of a nearly integrable system. We provide an upper bound to the diiusion speed, which turns out to be of superexponentially small size exp(exp(?1=%)), % being the distance from the invariant torus. We also discuss the connection of this result with the existence of many invariant tori close to the considered one.
