Isolated cold plasma regions - Observations and their relation to possible production mechanisms
Regions of enhanced cold plasma, isolated from the main plasmasphere along the Explorer 45 (S³-A) orbit in the equatorial plane, have been detected by using the sheath-induced potentials seen by theExpand

Penetration of low‐energy protons deep into the magnetosphere
By using a simple model with constant convection electric field and a dipole magnetic field, plasma flow patterns are calculated with the convection fields as scale factors. Unlike other particleExpand

EFFECTS ON THE PLASMASPHERE OF A TIME-VARYING CONVECTION ELECTRIC FIELD.
Abstract The time evolution of the plasmasphere has been investigated theoretically, using simple computational models. The magnetic field is assumed to be dipolar and time-independent, but theExpand

Dynamics of midlatitude light ion trough and plasmatails. [from data obtained on OGO-4]
Light ion trough measurements near midnight made by the RF ion mass spectrometer on OGO-4 operating in the high resolution mode in Feb. 1968 reveal the existence of irregular structure on the lowExpand

Dynamics of Mid-latitude light ion trough and plasma tails
Light ion trough measurements near midnight made by the Bennett RF ion mass spectrometer on Ogo 4 operating in the high-resolution mode reveal the existence of irregular structure on the low-latitudeExpand

Plasma tail interpretations of pronounced detached plasma regions measured by Ogo 5
Measurements of the light ion thermal plasma distribution in the magnetosphere frequently show apparent isolated patches of enhanced plasma density in the trough region beyond the main plasmasphere.Expand

Plasma flow in the magnetosphere.
We have constructed a mathematical model of the magnetosphere in which a large-scale uniform electric field, representing plasma flow from the tail, is superimposed on the geomagnetic field. InExpand

High‐latitude troughs and the polar cap boundary
Troughs in the thermal plasma densities detected in the top side ionosphere by the ion mass spectrometer on Ogo 6 are frequently observed at high latitudes. The position and characteristics of theExpand

Diurnal variation of thermal plasma in the plasmasphere
Abstract All of the OGO-5 light ion density measurements (covering the period from March 1968 to May 1969) obtained from the Lockheed Light Ion Mass Spectrometer were used to determine the averageExpand
