Minimum and Maximum Variance Analysis
The main purpose of minimum or maximum variance analysis (MVA) is to find, from single-spacecraft data, an estimator for the direction normal to a one-dimensional or approximately one-dimensionalExpand

Magnetopause structure and attitude from Explorer 12 observations.
It is shown how satellite magnetometer data at a magnetopause penetration can be used to determine the vector normal to the magnetopause current layer and the magnetic-field component along thisExpand

Magnetic field reconnection
A reasonably detailed description is obtained of the current status of our understanding of magnetic field reconnection. The picture that emerges is of a process, simple in concept but extremelyExpand

Plasma acceleration at the Earth's magnetopause: evidence for reconnection
A characteristic of magnetic field reconnection is the acceleration of plasma as it flows across a rotational discontinuity. At the Earth's magnetopause this effect has only been observed recentlyExpand

Adiabatic particle orbits in a magnetic null sheet
The adiabatic theory is presented for charged particles moving in a region where the main component of the magnetic field reverses its direction. The unperturbed field configuration isExpand

Modulation instability of circularly polarized Alfvén waves
The stability of a finite amplitude circularly polarized Alfven wave of wave number k0 is studied by using the two-fluid isentropic equations. Linear perturbation analysis, involving two sidebandExpand

Extended magnetic reconnection at the Earth's magnetopause from detection of bi-directional jets
Magnetic reconnection is a process that converts magnetic energy into bi-directional plasma jets; it is believed to be the dominant process by which solar-wind energy enters the Earth'sExpand

Explorer 12 observations of the magnetopause current layer
The variation in magnetic field magnitude at magnetopause is examined with the objective of separating boundaries of the rotational-discontinuity type from those of the tangential-discontinuity type.Expand

Magnetic field reconnection in cosmic plasmas
A brief review is presented of the concept of magnetic field reconnection or merging. This process occurs whenever an electric field is present along a separator line in the magnetic field. The basicExpand
