Interplanetary Magnetic Fields and Cosmic Rays

Physical Review, 1955
The existence in the region around the sun of a field-free cavity in the galactic magnetic field seems indicated by the low-energy cosmic rays that reach the earth from the sun. Such a cavity would be produced by the solar corpuscular emission. A mean radius of the order of 200 times the distance from the sun to the earth may be estimated for this ...

Solar wind and interplanetary magnetic field

Reviews of Geophysics, 1967
A brief history is presented of some of our ideas regarding the solar wind. The basic physical principles of supersonic expansion are discussed. An analogy is drawn with the flow of an ideal gas through a rocket‐engine nozzle. Supersonic expansion of a stellar corona requires a stellar and coronal temperature lower than a specified maximum.

The effect of an interplanetary magnetic field on the solar wind

Journal of Geophysical Research, 1964
A weak interplanetary magnetic field is shown to be compressed into a boundary layer of high magnetic-field intensity several earth radii deep at the surface of the magnetosphere. Thus, if the solar wind consisted of streams of plasma interspersed with an interplanetary magnetic field, magnetic intensity beyond the magnetopause would be expected to ...

Coronal and interplanetary magnetic field models

AIP Conference Proceedings, 1999
We provide an historical perspective of coronal and interplanetary field models. The structure of the interplanetary medium is controlled by the coronal magnetic field from which the solar wind emanates. This field has been described with “Source Surface” (SS) and “Heliospheric Current Sheet” (HCS) models.

Interplanetary Magnetic Field Changes and the Magnetotail

1979
The latest topical review (Burch, 1974) of magnetospheric effects directly related to the interplanetary magnetic field (IMF) described several observed associations between IMF changes and variations within the geomagnetic tail. The most firmly established among these was the good correlation between increases in the magnetic field intensity inside ...
