Electron-cyclotron maser emission - Relative growth and damping rates for different modes and harmonics. [of auroral kilometric radiation]
- D. B. Melrose, G. A. Dulk, R. Hewitt
- Physics
- 1 February 1984
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 second… Expand
Pulsar radiation belts and transient radio emission
- Q. Luo, D. B. Melrose
- Physics
- 22 April 2007
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 the… Expand
Low Altitude Solar Magnetic Reconnection, Type III Solar Radio Bursts, and X-ray Emissions
- I. Cairns, V. Lobzin, +39 authors C. Williams
- Physics, Medicine
- Scientific Reports
- 26 January 2018
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 collective… Expand
Oscillating pulsar polar gaps
- Q. Luo, D. B. Melrose
- Physics
- 12 April 2008
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. An… Expand
Anisotropic weak turbulence of Alfvén waves in collisionless astrophysical plasmas
- Q. Luo, D. B. Melrose
- Physics
- 14 February 2006
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 the… Expand
Wave dispersion in pulsar plasma: 3. Beam-driven instabilities.
- M. Rafat, D. B. Melrose, A. Mastrano
- Physics
- 5 June 2019
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 only… Expand
Pulsar radio emission mechanism: Why no consensus?
- D. B. Melrose, M. Rafat
- Physics
- 1 December 2017
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 and… Expand
Pulsar radio emission mechanisms: a critique
- D. B. Melrose, M. Rafat, A. Mastrano
- Physics
- 27 June 2020
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 emission… Expand
Electron–Langmuir wave resonance in three dimensions
- J. Harding, I. Cairns, D. B. Melrose
- Physics
- 12 February 2020
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 the… Expand
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 theory… Expand
