Physics in Ultra-strong Magnetic Fields
In magnetic fields stronger than BQ ≡ m 2 ec /h̄e = 4.4 × 10 Gauss, an electron’s Landau excitation energy exceeds its rest energy. I review the physics of this strange regime and some of its implications for the crusts and magnetospheres of neutron stars. In particular, I describe how ultra-strong fields • render the vacuum birefringent and capable of distorting and magnifying images (“magnetic...
متن کاملMagnetic Properties of Intermediate-mass Stars
Magnetic fields play an important role in producing and modifying the photospheric chemical peculiarities of intermediate-mass main sequence stars. This article discusses the basic theory and methods of measurement used to detect and characterise stellar magnetic fields, and reviews our current knowledge of selected characteristics of magnetic fields in intermediate-mass stars.
متن کاملthe relationship between topic familiarity and guessing lexical meaning and retention among iranian efl learners
the skill of reading in english as a foreign language is an important and challenging one which is affected both by linguistic and extra linguistic factors. since vocabularies are part and parcel of every reading comprehension text, knowing enough vocabulary always facilitates this process. however, guessing strategy as one of the most important strategies has consistently ignored by language l...
15 صفحه اولRadial Oscillations of Rotating Strange Stars in Strong Magnetic Fields
In this paper we study radial oscillations of the rotating strange stars in strong magnetic fields in the Density Dependent Quark Mass (DDQM) model. We see that increase of frequency i.e. difference in frequency of rotating and non-rotating stars is more for higher magnetic fields. The change is small for low mass stars but it increases with the mass of the star. This change of frequency is sig...
متن کاملPhysical Processes in Strong Magnetic Fields of Neutron Stars
Neutron stars have inferred surface magnetic fields of up to 10 Gauss, in the case of radio pulsars, and up to possibly 10 Gauss, in the case of Soft Gamma-Ray Repeaters and Anomalous X-ray Pulsars. In fields this high, QED effects will profoundly change the characteristics of continuum radiation processes such as synchrotron emission and Compton scattering and will also allow the possibility o...
