Current theoretical models for the outflows/jets from active galactic nuclei, X-ray binaries, and young stellar objects involve large-scale magnetic fields threading an underlying accretion disk. We suggest that such a disk is subjected to warping instability and retrograde precession driven by magnetic torques associated with the outflow. The growth timescale for the disk warp and the precession period are of order the radial infall time of the disk. These effects may be relevant to jet… Expand

Theory of Disk Accretion onto Magnetic Stars
Disk accretion onto magnetic stars occurs in a variety of systems, including accreting neutron stars (with both high and low magnetic fields), white dwarfs, and pro- tostars. We review some of theExpand
Warping and Precession of Accretion Disks around Magnetic Stars: Nonlinear Evolution
The inner region of the accretion disk around a magnetized star (T Tauri star, white dwarf, or neutron star) is subjected to magnetic torques that induce warping and precession of the disk. TheseExpand
Formation of Protostellar Jets as Two-Component Outflows from Star-Disk Magnetospheres
Axisymmetric magnetohydrodynamic simulations have been applied to investigate (1) the interrelation between a central stellar magnetosphere and stellar wind with a surrounding magnetized diskExpand
Discs, outflows, and feedback in collapsing magnetized cores
Abstract The pre-stellar cores in which low mass stars form are generally well magnetized. Our simulations show that early protostellar discs are massive and experience strong magnetic torques in theExpand

Abstract In this review the recent development concerning the large-scale evolution of stellar magnetospheres in interaction with the accretion disk is discussed. I put emphasis on the generation ofExpand
Warping and Precession in Galactic and Extragalactic Accretion Disks
The Bardeen-Petterson general relativistic effect has been suggested as the mechanism responsible for precession in some accretion disk systems. Here we examine separately four mechanisms (tidal,Expand

Accretion onto supermassive black holes produces both the dramatic phenomena associated with active galactic nuclei and the underwhelming displays seen in the Galactic Center and most other nearbyExpand
Precessing Jet and Large Dust Grains in the V380 Ori NE Star-forming Region
The V380 Ori NE bipolar outflow was imaged in the SiO and CO J = 1 → 0 lines, and dense cores in L1641 were observed in the 2.0–0.89 mm continuum. The highly collimated SiO jet shows point-symmetricExpand
Early Evolution of Disk, Outflow, and Magnetic Field of Young Stellar Objects: Impact of Dust Model
The formation and early evolution of low mass young stellar objects (YSOs) are investigated using three-dimensional non-ideal magneto-hydrodynamics simulations. We investigate the evolution of YSOsExpand
A COMMON SOURCE OF ACCRETION DISK TILT
Many different system types retrogradely precess, and retrograde precession could be from a tidal torque by the secondary on a misaligned accretion disk. However, a source that causes and maintainsExpand

GRO J1655-40, a recently discovered black-hole candidate, is an ideal system for studying jets of material from the accretion disk around a black hole. Observations of the radio emission show twoExpand
Magnetohydrodynamic production of relativistic jets.
TLDR
A magnetohydrodynamic model may explain the basic features of observed jets, including their speed and amount of collimation, and some of the details in the behavior and statistics of different jet-producing sources. Expand
Warped accretion discs and the long periods in X-ray binaries
TLDR
It is shown that an instability of the response of the disc to the radiation reaction force from the illumination by the central source can cause it to tilt out of the orbital plane and precess in something like the required manner. Expand
Precession of Collimated Outflows from Young Stellar Objects
We consider several protostellar systems in which either a precessing jet or at least two misaligned jets have been observed. We assume that the precession of jets is caused by tidal interactions inExpand

A wind passing over a surface may cause an instability in the surface, such as the flapping seen when wind blows across a flag or waves when wind blows across water. We show that when a radiallyExpand
