Rescattering effects in the decay of the A1
- 1976
-
Ingår i: Nuclear Physics, Section B. - : Elsevier BV. - 0550-3213. ; 116:2, s. 301-316
-
Tidskriftsartikel (refereegranskat)abstract
- Rescattering effects in the 3π system in the A1 region are studied with a method, which fulfils unitarity and has the proper analytic structure. Fairly small effects are obtained which confirm the result found in amplitude analyses, neglecting rescattering corrections, that the phases of the JP = 1+ amplitudes vary only very little over the A1 region. Similar results hold for the Q enhancement.

Significance of magnetospheric research for progress in astrophysics

- Recent in situ measurements have led to a substantial revision of our picture of the magnetosphere and parts of the heliosphere. This concerns the character and distribution of electric fields and currents, the ways in which charged particles are energised, and the chemical composition of the magnetospheric plasma. This revision reflects the fact that real cosmic plasmas behave in fundamentally different ways than predicted by the traditional, idealised models used in magnetospheric physics and in astrophysics. The new understanding of the general properties of cosmic plasma gives us an improved basis on which to interpret astrophysical observations.

Electric-current model of the magnetosphere
- 1979
-
Ingår i: ESA Journal. - : European Space Agency. - 0379-2285. ; 3:2, s. 91-99

Tidskriftsartikel (refereegranskat)abstract
- A translation of the traditional field description of the magnetosphere into a particle (electric current) description is offered. Focus is on the energy transfer from the solar wind. The solar wind flow through the magnetic field acts as an electric generator. Its power is transferred to the magnetosphere through four main circuits. These are the magnetopause circuit, the solar wind/auroral circuit, the tail circuit, and the front circuit. A fifth circuit, the substorm circuit, is also very often energized. When the tail circuit flares, the current is partly redirected over the auroral zone, flowing in what is called the 'substorm circuit'.

Electric currents in cosmic plasmas

Tidskriftsartikel (refereegranskat)abstract
- Since the beginning of the century, physics has been dualistic in the sense that some phenomena are described by a field concept and others by a particle concept. This dualism is essential also in the physics of cosmic plasmas: some phenomena should be described by a magnetic field formalism, and others by an electric current formalism. During the first period of evolution of cosmic plasma physics the magnetic field aspect has dominated, and a fairly exhaustive description has been given of those phenomena, like the propagation of waves, which can be described in this way. We have now entered a second period, which is dominated by a systematic exploration of the particle (or current) aspect. A survey is given of a number of phenomena which can be understood only from the particle aspect. These include the formation of electric double layers, the origin of ‘explosive’ events like magnetic substorms and solar flares, and further, the transfer of energy from one region to another. A useful method of exploring many of these phenomena is to draw the electric circuit in which the current flows and to study its properties. A number of simple circuits are analyzed in this way.

Saturnian rings
- 1976

Ingår i: Astrophysics and Space Science. - : Kluwer Academic Publishers. - 0004-640X .- 1572-946X. ; 43:1, s. 97-104

Tidskriftsartikel (refereegranskat)abstract
- The structure of the Saturnian rings is compared with the asteroidal belt and the relative importance of the resonance effects and the cosmogonic effects is evaluated. No visible correspondence to the Kirkwood gaps is expected theoretically, nor is there any observational evidence for such effects. The only possible resonance is the 1:1 resonance with Saturn's spin period.Cosmogonic ‘shadow’ effects are responsible for the main features of the ring structure, including Cassini's division, the limit between the B and C ring, and possibly also Guérin's division.
