Flare star, any star that varies in brightness, sometimes by more than one magnitude, within a few minutes. The cause is thought to be the eruption of flares much larger than, but otherwise similar to, those observed on the Sun. Flare stars are sometimes
including at normal incidence and with finite-gradient plasmas. Our numerical results support theω−4/3scaling of the synchrotron emission model as a limiting efficiency of the process under most conditions. The highest frequencies that can be generated with this scaling are...

The first observation of x-ray emission spectra of multiply charged ions in the plasma produced by a 35-fs laser pulse with an intensity up to 10<SUP>17</SUP> W cm<SUP>-2</SUP> in CO<SUB>2</SUB> and Kr gas jet targets is reported. The emission in the wavelength ranges of the...
Effects of spin polarization and self-consistent iterations on energy levels and charge distribution are explored; comparison is made to band structure results. The calculated X-ray emission spectra are in reasonably good agreement with experiment....
Here, we present a method to determine the temperature-dependent atomic electron-phonon induced spin-flip scattering rate. We exploit the quantifiable change in the decay peak intensities in static x-ray emission spectroscopy (XES) spectra when changing the temperature,i.e. when changing the phonon...
IV.I X-Ray Emission About 10% of the known globular clusters in the galaxy are X-ray sources. Not all of them, however, show the bursting activity with which the class is usually identified. The burst sources are due to accretion onto a neutron star of matter from a low-mass companion...
The distinct processes are involved in X - ray emission. X 射线的发射,包含两种不同的过程. 辞典例句 Doctors discovered the hematoma by using a special computer X - ray called a " ket - skein ". 医生们使用了一种叫 “ 铜束 ” ( ket -skein)的特别的电脑x光机,检查出了脑血肿的准确位置....
However, until persuasive evidence for binarity is found we are left with the intriguing possibility that the hard X-ray emission is produced entirely by the Wolf-Rayet star. 展开 关键词: radio continuum : stars stars : individual (HD 165688 stars : mass loss stars : winds, outflows stars ...
With the advances of high photon flux at new-generation synchrotron radiation facilities, advanced X-ray spectroscopies with high-energy resolution, such as high-energy-resolution fluorescence-detected XAS (HERFD-XAS), nonresonant X-ray emission spectroscopy (XES) and resonant inelastic X-ray scatterin...
