Regularities and Systematic Trends on Zr IV Stark Widths

Regularities and systematic trends among the Stark widths of 18 Zr IV spectral lines obtained by modified semiempirical approach have been discussed. Also we compared those calculated Stark broadening parameters with estimates according to Cowley, Purić et al. and Purić and Šćepanović and checked the possibility to find some new estimates. It is demonstrated as well that the formula of Cowley (...

Experimental and calculated Stark widths within the Kr I spectrum.

On the basis of the precisely recorded 20 neutral krypton (Kr I) line shapes (in the 5s-5p and 5s-6p transitions), we have obtained the basic plasma parameters, i.e., electron temperature (T) and electron density (N) using our line deconvolution procedure in a plasma created in a linear, low-pressure, pulsed arc discharge operated in krypton. The mentioned plasma parameters have also been measu...

Hydrogen Stark broadened Brackett lines

Stark broadened lines of the hydrogen Brackett series are computed for the conditions of stellar atmospheres and circumstellar envelopes. The computation is performed within the Model Micro eld Method, which includes the ion dynamic e ects and makes the bridge between the impact limit at low density and the static limit at high density and in the line wings. The computation gives the area norma...

Integrability of Some Charged Rotating Supergravity Black Hole Solutions in Four and Five Dimensions

We study the integrability of geodesic flow in the background of some recently discovered charged rotating solutions of supergravity in four and five dimensions. Specifically, we work with the gauged multicharge Taub-NUT-Kerr-(Anti) de Sitter metric in four dimensions, and the U(1)3 gauged charged-Kerr-(Anti) de Sitter black hole solution of N = 2 supergravity in five dimensions. We explicitly ...

Emission of charged particles from four- and five-dimensional black holes

Recently Das and Mathur found that the leading order Hawking emission rate of neutral scalars by near-extremal D = 5 black holes is exactly reproduced by a string theoretic model involving intersecting D-branes. We show that the agreement continues to hold for charged scalar emission. We further show that similar agreement can be obtained for a class of near-extremal D = 4 black holes using a m...
