General tachyon absorption by Kerr-Newman black holes: Thermodynamic consequences

  • J. G. Shanks
Research Articles


Following the analyses of B. Carter and J. V. Narlikar, the nature of the incomplete, spacelike trajectories about a charged, rotating black hole is described. The study concentrates on those paths which a charged tachyon would follow, incident from off the equatorial plane (on whichθ=π/2). The effect of the absorption upon the black hole is calculated and it is concluded that forπiπ/2 only certain charged tachyons will reduce its entropy. However, a sustained bombardment by such particles could cause the singularity to be exposed.
