... Credit Copyright: IMAGE Satellite , NASA Explanation: What are auroras made out of? Most auroras are caused by the solar wind exciting electrons that are funneled down the Earth's magnetic field . ... A proton aurora captured by the IMAGE satellite in ultraviolet is shown above ringing the north magnetic pole of planet Earth. Most electrons and protons never reach the Earth to cause auroras because they are completely deflected away at a great distance by the Earth's magnetic field . ...

... Astronomers of the SAO together with an international group of scientists have proposed an explanation to the long-standing mystery of why magnetic fields are more common amongst cool white dwarf stars than amongst young and hotter ones. ... As the result magnetic white dwarfs demonstrate excess in their frequencies in the temperature range below 14000K. The authors also show that the strongly magnetic white dwarfs are of the oldest stars of the Galaxy originated from intermediate-mass relic stars. ...

Solar Flare Origin - critical analysis" Lev Pusti'lnik We analyze current approach to solar flare origin in 3 aspects: a. Pre-flare equilibrium state of current-magnetic structure above active region and its evolution to flare state, b. Possible reasons of stability loss with transition of system in flare state c. Flare energy release in turbulent current sheet and particle acceleration in this system. ...

Most current theories for magnetospheric emission can be grouped into polar cap, outer gap, and nebular models. These models, at least in some cases, need not be mutually exclusive; the Crab pulsar (among others), for example, shows clear evidence for pulsed emission from the magnetosphere and unpulsed emission from the surrounding nebula. ... This suggestion is strengthened by observation of a distinct soft emission component, consistent with the cooling scenario, from several of these pulsars. ...
