In the present work, in order to estimate semi-amplitude of radial velocity, we evaluate contribution Doppler beaming effect phase curves all confirmed extrasolar planets (2776, September 2019), observed so far by Kepler telescope. By modeling tiny photometric variations (reflection, ellipsoidal and effects) light curves, found that best observational data are close agreement with theoretical p...

We use a set of carefully selected published average multifrequency polarimetric observations for six bright cone dominated pulsars and devise a method to combine the multifrequency polarization position angle (PPA) sweep traverses. We demonstrate that the PPA traverse is in excellent agreement with the rotating vector model over this broad frequency range confirming that radio emission emanate...

Strong directional selectivity is theoretically predicted and experimentally validated at the microwave frequencies in the beaming regime for a single subwavelength slit in nonsymmetric metallic gratings with double-side corrugations. The operation regime can be realized at a fixed angle of incidence when the surfaceplasmon assisted transmission is significant within a narrow range of observati...

The most luminous GRBs can be explained in terms of models involving stellar mass central engines only if the ejecta are beamed. As was pointed out by Rhoads (1997), the dynamics of the blast wave, formed by the beamed ejecta sweeping the external gas, can be significantly modified by the sideways expansion. This is because in this case the surface of the blast wave increases faster than just d...
