... The are two main sources of magnetospheric electric fields. The other is the solar wind related, dawn-to-dusk directed ("convection") field, and the other is the co-rotation electric field related to the rotation of the Earth along its spin axis. The electric fields have a strong effect on the drift paths of the magnetospheric plasma . ... The energetic particles, following the magnetic drifts more readily, are also affected by the convection field. ... Space Physics Text Book of Oulu ...

... A second method to account for illumination problems in the flat fields is to remove the large scale pattern from the flat field itself. This is useful if there are no reasonable blank sky calibration frames and the astronomical exposures are evenly illuminated but the flat fields are not. ... Obviously, after having obtained the illumination corrected flat field it is reasonable to replace the original flat fields by the corrected flat fields in the reduction table. ...

Tsfasman and Vl\u adu\c t defined the set of invariants $\{\phi_q, q \text{ is a prime power, } \mathbb{R} \text{ or }\mathbb{C}\}$ of infinite global fields, but the properties of this sets are still not known. ... In this direction, I will talk about the constructions of infinite global fields having $n$ prescribed non-zero invariants, and of others having $n$ prescribed zero invariants. ...

... 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. ...

... 2 Magnetic Field . ... A magnetized bar has its power concentrated at two ends, its poles ; they are known as its north (N) and south (S) poles, because if the bar is hung by its middle from a string, its N end tends to point northwards and its S end southwards. ... That flow became known as an electric current . ... An electric current produced a magnetic force! ... The fundamental nature of magnetism was not associated with magnetic poles or iron magnets, but with electric currents . ...

SAS home . ... EPIC background spectra are normally extracted from regions of the observation field-of-view, once "contamination" due to individual discrete celestial sources has been removed. ... In order to cope with this situation, blank sky event lists can be downloaded from the XMM-Newton Science Operations Center web site. ... It is in principle possible as well to extract background spectra from blank field event lists, if the spectrum accumulation regions are defined in sky coordinates. ...
