Electron-cyclotron maser emission - Relative growth and damping rates for different modes and harmonics. [of auroral kilometric radiation]
We calculate and compare the temporal growth rate and the number of e-folding growths for the following wave modes due to a loss-cone-driven cyclotron maser: fundamental x, o, and z modes and secondExpand

Pulsar radiation belts and transient radio emission
It is proposed that radiation belts similar to the ones in the planetary magnetosphere can exist for a pulsar with a relatively long period and a strong magnetic field. In the belts located in theExpand

Low Altitude Solar Magnetic Reconnection, Type III Solar Radio Bursts, and X-ray Emissions
Type III solar radio bursts are the Sun’s most intense and frequent nonthermal radio emissions. They involve two critical problems in astrophysics, plasma physics, and space physics: how collectiveExpand

Oscillating pulsar polar gaps
An analytical model for oscillating pair creation above the pulsar polar cap is presented in which the parallel electric field is treated as a large amplitude, superluminal, electrostatic wave. AnExpand

Anisotropic weak turbulence of Alfvén waves in collisionless astrophysical plasmas
The evolution of the Alfven turbulence due to three-wave interactions is discussed using kinetic theory for a collisionless, thermal plasma. There are three low-frequency modes, analogous to theExpand

Wave dispersion in pulsar plasma: 3. Beam-driven instabilities.
Beam-driven instabilities are considered in a pulsar plasma assuming that both the background plasma and the beam are relativistic Juttner distributions. In the rest frame of the background, the onlyExpand

Pulsar radio emission mechanism: Why no consensus?
Pulsar radio emission involves a coherent emission mechanism involving relativistic particles, but there is no consensus on what the specific emission mechanism is. There are arguments for andExpand

Pulsar radio emission mechanisms: a critique
We consider critically the three most widely favored pulsar radio emission mechanisms: coherent curvature emission (CCE), beam-driven relativistic plasma emission (RPE) and anomalous Doppler emissionExpand

Electron–Langmuir wave resonance in three dimensions
In the one-dimensional (1D) treatment of Langmuir wave generation by a particle distribution via the kinetic beam instability, there is a one-to-one resonance between the electron speed v and theExpand

SCINTILLATIONS AND MICRO LENSING
It is shown how the theory of scintillation may be applied to treat gravitational lensing. The theory is applied to microlensing by a system of N point masses. It is shown that scintillation theoryExpand
