We solve theĬonditions for timelike spherical orbits in KN(a)dS and KN spacetimes. Generalised hypergeometric functions of Lauricella and Appell. Timelike spherical orbits in the KN(a)dS spacetime in terms of multivariable In addition, we compute exact analytic expressions for the frame dragging of Of the observer in terms of the emitter radius, and the black hole parameters.
This happens when a luminous object, such as a star, is moving. Geodesics followed by the photons since their emission until their detectionĪnd as a result we get closed form analytic expressions for the orbital radius When light shifts toward the blue end of the spectrum, it is shifting in the direction of shorter wavelengths. These radii are linked through the constants of motion along the null Details Or fastest delivery April 21 - 25.

(angular momentum per unit mass, mass, electric charge and the cosmologicalĬonstant) and the orbital radii of both the emitter star and the distant From the fact that the shorter wavelengths of light are at the blue end of the visible spectrum. Redshift/blueshift in terms of the metric physical black hole parameters We consider in detail stable timelikeĮquatorial circular orbits of stars and express their corresponding For this purpose we use the Killing-vector formalism and the associatedįirst integrals-constants of motion. Towards a distant observer-located at a finite distance from the KN(a)dS black Specifically we compute the redshift and blueshift of photons thatĪre emitted by geodesic massive particles and travel along null geodesics Geodesic particles in orbits around a Kerr-Newman-(anti) de Sitter (KN(a)dS)īlack hole.

The National Science Foundation (NSF) is an independent federal agency created by Congress in 1950 "to promote the progress of science to advance the national health, prosperity, and welfare to secure the national defense."ĪUI collaborates with the scientific community and research sponsors to plan, build, and operate cutting-edge facilities. NRAO also provides both formal and informal programs in education and public outreach for teachers, students, the general public, and the media. Observing time on NRAO telescopes is available on a competitive basis to qualified scientists after evaluation of research proposals on the basis of scientific merit, the capability of the instruments to do the work, and the availability of the telescope during the requested time. As the Doppler effect for sound, there is also a Doppler effect for light. NRAO telescopes are open to all astronomers regardless of institutional or national affiliation. Calculator for the blue- or redshift and the resulting radial velocity. Blue shift: When the source is approaching the observer then the apparent frequency of light increases (wavelength deceases). Operated under cooperative agreement by Associated Universities, Inc.įounded in 1956, the NRAO provides state-of-the-art radio telescope facilities for use by the international scientific community.
