  • Accretion disks - What do we know about them? 
    Prasanna, A. R (Astronomical Society of India, 1982-09)
    This essay briefly describes the present status of research on accretion disks around compact objects - in particular, blackholes - covering both the thin and thick disks. Significant results from various analyses regarding ...
  • Irregular Singularity of the Magnetorotational Instability in a Keplerian Disk 
    Furukawa, M; Yoshida, Z; Hirota, M; Krishan, V (University of Chicago Press, 2007-04)
    The center of a Keplerian disk is an irregular singularity for the eigenfunctions of magnetorotational instabilities. The system is studied using the small-radius approximation, which by no means implies that the analysis ...
  • Relativistic beams, thick accretion disks and active galactic nuclei 
    Wiita, P. J; Kapahi, V. K; Saikia, D. J (Astronomical Society of India, 1982-12)
    We review recent analyses of observations of radio galaxies and quasars that support the relativistic beaming models and appear to produce values for the Lorentz factors of the radiating mateiral in the nuclear jets. Thick ...
