    Second-Harmonic Resonance with Parametric Excitation and Dam**

    The equations da/dt = -σu + μa* +λa*b, db/dt =σ 1 b+νa 2 describe second-harmonic resonance of two small-amplitude standing water waves with Faraday ...

    Removing the Pressure Limitations on Flux Pile-Up Reconnection

    In a recent Letter, Litvinenko, Forbes, and Priest (1996) claimed that the rate of the very fast flux-pile up reconnection is severely limited by the effects of plasma pressure. They considered however only tw...

    Magnetic Annihilation in Colliding-Wind Binary Systems

    We investigate the possibility that a stagnation-point magnetic reconnection model may account for the particle acceleration necessary for the generation of nonthermal radio emission in the Wolf-Rayet binary s...

    The role of vorticity in 3D magnetic field annihilation

    We show that magnetic field annihilation depends strongly on the behaviour of the vorticity and is quite different in 2D and 3D. In 3D the vorticity can be increased locally by the stretching of vortex lines (...

    Magnetoacoustic-gravity surface waves

    The linearized theory for the parallel propagation of magnetoacoustic-gravity surface waves is developed and a dispersion relation obtained for the case of an isothermal interface of a uniform horizontal magne...

    Resistive ballooning line-tied boundary conditions

    Ideal and resistive ballooning modes are investigated for different ratios of a two-layer stratified density region representing a model for the photospheric/coronal boundary. Construction of the ballooning eq...
