On the Origin of Magnetospheric Line Radiation

We present a short overview of results obtained by a systematic survey of line radiation events observed by the DEMETER spacecraft at an altitude of 700 km. We find two different classes of events that can be easily distinguished by the observed frequency separation of lines forming the event – if it is 50/100 Hz or 60/120 Hz then the event is most probably caused by electromagnetic radiation f...

Curvature radiation in pulsar magnetospheric plasma

We consider the curvature radiation of the point-like charge moving relativistically along curved magnetic field lines through a pulsar magnetospheric electron-positron plasma. We demonstrate that the radiation power is largely suppressed as compared with the vacuum case, but still at a considerable level, high enough to explain the observed pulsar luminosities. The emitted radiation is polariz...

Pickup Protons and Water Ions at Comet Halley Comparisons with Giotto Observations

A quasi-linear diffusion model including both pitch angle and energy diffusion, adiabatic ompression and convective motion with the solar wind flow has been used to investigate the cometary ion pickup process along the Sun-comet line at comet Halley. The total pickup ion densities and magnetic turbulence spectrum levels observed by Giotto were used to constrain the quasi-linear model. Compariso...

Observations of T Tauri Disks at Sub-AU Radii: Implications for Magnetospheric Accretion and Planet Formation

We determine inner disk sizes and temperatures for four solar-type (1-2 M⊙) classical T Tauri stars (AS 207A, V2508 Oph, AS 205A, and PX Vul) using 2.2 μm observations from the Keck Interferometer. Nearly contemporaneous near-IR adaptive optics imaging photometry, optical photometry, and high-dispersion optical spectroscopy are used to distinguish contributions from the inner disks and central ...

Mapping Magnetospheric Equatorial Regions at Saturn from Cassini Prime Mission Observations

Saturn’s rich magnetospheric environment is unique in the solar system, with a large number of active magnetospheric processes and phenomena. Observations of this environment from the Cassini spacecraft has enabled the study of a magnetospheric system which strongly interacts with other components of the saturnian system: the planet, its rings, C.S. Arridge ( ) · G.H. Jones Mullard Space Scienc...
