Electron Orbits in Solar Reconnecting Current Sheets
We investigate the orbits of charged particles (electrons) that interact with a 3D-solar type reconnecting current sheet (RCS). The magnetic field used is a linearized Harris type model. Particles are accelerated by a super-Dreicer electric field. Taking advantage of the translational symmetries of the fields, the orbits computation is simplified to integration of the equations of motion in a H...
متن کاملPlasmoids in Reconnecting Current Sheets: Solar and Terrestrial Contexts Compared
Magnetic reconnection plays a crucial role in violent energy conversion occurring in the environments of high electrical conductivity, such as the solar atmosphere, magnetosphere, and fusion devices. We focus on the morphological features of the process in two different environments, the solar atmosphere and the geomagnetic tail. In addition to indirect evidence that indicates reconnection in p...
متن کاملAn Energy Release Mechanism of Current Loops in the Solar Atmosphere : Solar Flares and Corona Heating
A mechanism is proposed to account for the energy release by a bipolar current loop in the solar atmosphere. This mechanism is electromagnetic in nature and utilizes the non-zero J X B forces. No dissipation of the magnetic energy by resistivity, magnetic reconnection, or circuit interruption is required. From the observed fact that bipolar current loops do exist in quasi-equilibrium in the sol...
متن کامل7Li PRODUCTION IN SOLAR FLARES
The Y ohkoh satellite has registered X-ray spectra of two solar Ñares with a linelike feature in the region 400È500 keV. Analysis shows that this feature can be interpreted as gamma-ray lines from excited 7Li and 7Be produced from a ] a reactions. The 7Li production rate in the solar atmosphere is estimated from these observations. The lower limit on the Ñare-produced 7Li abundance on the Sun i...
متن کاملSpheromaks, solar prominences, and Alfvén instability of current sheets
Three related efforts underway at Caltech are discussed: experimental studies of spheromak formation, experimental simulation of solar prominences, and Alfvén wave instability of current sheets. Spheromak formation has been studied by using a coaxial magnetized plasma gun to inject helicity-bearing plasma into a very large vacuum chamber. The spheromak is formed without a flux conserver and int...
