Spectrum for the electric dipole which nonradially falling into a black hole

Abstract

The electromagnetic bremsstrahlung spectrum of the dipole which falls along a spiral orbit into the Schwarzschild black hole was found. The characteristic features of this electromagnetic spectrum can be used for determination of the black hole mass. This new way (if implemented) provides higher accuracy of the determination of the black hole mass. Also these features in the spectrum can be used for the determination of the some physical processes in the black hole magnetosphere and in the accretion disk. It is also shown that the asymptotic behavior of this spectrum (at high frequencies) is practically independent from the impact parameter of the falling dipole. *
