Solar Activity: Triennial Report of IAU Commission 10 (2006-2009)
J. A. Klimchuk, L. van Driel-Gesztelyi, C. J. Schrijver +9
Commission 10 deals with solar activity in all of its forms, ranging from the smallest nanoflares to the largest coronal mass ejections. This report reviews scientific progress ove…
Oscillating pulsar polar gaps
Q. Luo, D. B. Melrose
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, electr…
What is special about high magnetic field radio pulsars? -- First results from the multifrequency polarimetry
N. Vranevsevic, R. N. Manchester, D. B. Melrose
The Parkes Multibeam Survey led to the identification of a number of long-period radio pulsars with magnetic field well above the 'quantum critical field' of ~ 4.4x10^13 G (HBRPs).…
Pair emission from bare magnetized strange stars
D. B. Melrose, R. Fok, D. P. Menezes
The dominant emission from bare strange stars is thought to be electron-positron pairs, produced through spontaneous pair creation (SPC) in a surface layer of electrons tied to the…
The induced turbulence effect on propagation of radio emission in pulsar magnetospheres
Qinghuan Luo, D. B. Melrose
The effect of photon-beam-induced turbulence on propagation of radio emission in a pulsar magnetosphere is discussed. Beamed radio emission with a high brightness temperature can g…
Anisotropic weak turbulence of Alfven waves in collisionless astrophysical plasmas
Q. Luo, D. B. Melrose
The evolution of Alfven turbulence due to three-wave interactions is discussed using kinetic theory for a collisionless, thermal plasma. There are three low-frequency modes, analog…
An empirical model for the polarization of pulsar radio emission
D. Melrose, A. Miller, A. Karastergiou +1
We present an empirical model for single pulses of radio emission from pulsars based on gaussian probability distributions for relevant variables. The radiation at a specific pulse…
Depolarization of radio bursts due to reflection off sharp boundaries in the solar corona
D. B Melrose
It is argued that depolarization of solar radio bursts requires reflection off boundary layers no thicker than about a wavelength (a few meters at most) between regions with large…
Quark stars within relativistic models
D. P. Menezes, C. Providencia, D. B. Melrose
Lately, it has been suggested that strange (quark) stars can be responsible for glitches and other observational features of pulsars. Some discussions on whether quark stars, if re…
Strange star equations of state revisited
D. P. Menezes, D. B. Melrose
Motivated by recent suggestions that strange stars can be responsible for glitches and other observational features of pulsar, we review some possible equations of state and their…
On the origin of the drifting subpulses in radio pulsars
G. Gogoberidze, G. Z. Machabeli, D. Melrose +1
A model for the main observational characteristics of the radio emission of pulsars with well organized drifting subpulses is presented. We propose that drifting subpulses result f…
Large-Amplitude, Pair-Creating Oscillations in Pulsar and Black Hole Magnetospheres
Amir Levinson, Don Melrose, Alex Judge +1
A time-dependent model for pair creation in a pulsar magnetosphere is developed. It is argued that the parallel electric field that develops in a charge-starved region (a gap) of a…
Interpretation of parabolic arcs in pulsar secondary spectra
Mark Walker, Don Melrose, Dan Stinebring +1
Pulsar dynamic spectra sometimes show organised interference patterns; these patterns have been shown to have power spectra which often take the form of parabolic arcs, or sequence…
Conservation of both current and helicity in a quadrupolar model for solar flares
Don Melrose
A model for a solar flare, involving magnetic reconnection transferring flux and current between current-carrying magnetic loops connecting two pairs of footpoints, is generalized…
New mechanism of pulsar radio emission
M. Gedalin, E. Gruman, D. B. Melrose
It is shown that pulsar radio emission can be generated effectively through a streaming motion in the polar-cap regions of a pulsar magnetosphere causing nonresonant growth of wave…
Scintillation-Induced Circular Polarization in Pulsars and Quasars
J. -P. Macquart, D. B. Melrose
We present a physical interpretation for the generation of circular polarization resulting from the propagation of radiation through a magnetized plasma in terms of a rotation meas…
Circular Polarization Induced by Scintillation in a Magnetized Medium
J. -P. Macquart, D. B. Melrose
A new theory is presented for the development of circular polarization as radio waves propagate through the turbulent, birefringent interstellar medium. The fourth order moments of…
Intergalactic Propagation of UHE Cosmic Rays
Abraham Achterberg, Yves A. Gallant, Colin A. Norman +1
We discuss the intergalactic propagation of ultra-high-energy cosmic rays (UHECRs) with energies E \geq 10^{18.5} eV. We consider the propagation of UHECRs under the influence of t…
Neutrino emission via the plasma process in a magnetized plasma
Malcolm Kennett, Don Melrose
Neutrino emission via the plasma process using the vertex formalism for QED in a strongly magnetized plasma is considered. A new vertex function is introduced to include the axial…
Stochastic Faraday Rotation
D. B. Melrose, J. -P. Macquart
Different ray paths through a turbulent plasma can produce stochastic Faraday rotation leading to depolarization of any linearly polarized component. Simple theory predicts that th…
Langmuir Wave Generation Through A Neutrino Beam Instability
S. J. Hardy, D. B. Melrose
A standard version of a kinetic instability for the generation of Langmuir waves by a beam of electrons is adapted to describe the analogous instability due to a beam of neutrinos.…
PULSARS WITH STRONG MAGNETIC FIELDS: POLAR GAPS, BOUND PAIR CREATION AND NONTHERMAL LUMINOSITIES
V. V. Usov, D. B. Melrose
Modifications to polar-gap models for pulsars are discussed for the case where the surface magnetic field, , of the neutron star is strong. For $B\ga4\times10^8\rm\,T$, the cu…
