X-ray Fluctuations from the Slim Disk
The responses of perturbations added into the optically thick, advection-dominated accretion disk (ADAD), what we call the slim disk (SD), are investigated through numerical simulations. Although it is proposed that the SD is thermally stable, I find that a perturbation added into the disk is not rapidly damped and moves through the disk in its free-fall time. After the perturbation moves, the ...
متن کاملThe Observational Appearance of Slim Accretion Disks
We reexamine the hypothesis that the optical/UV/soft X-ray continuum of Active Galactic Nuclei is thermal emission from an accretion disk. Previous studies have shown that fitting the spectra with the standard, optically thick and geometrically thin accretion disk models often led to luminosities which contradict the basic assumptions adopted in the standard model. There is no known reason why ...
متن کاملObservational Constraints on Dust Disk Lifetimes: Implications for Planet Formation
Thus far our impressions regarding the evolutionary time scales for young circumstellar disks have been based on small number statistics. Over the past decade, however, in addition to precision study of individual star/disk systems, substantial observational effort has been invested in obtaining less detailed data on large numbers of objects in young star clusters. This has resulted in a pletho...
متن کاملStability of a slim accretion disk around a black hole
Stability is examined for an optically thick, slim accretion disk around a black hole. We derive the fourth-order dispersion relation in a framework of a linear stability analysis. Also we obtain the approximate second-order relation which is convenient to diagnose the stability. By solving these relations for slim disk models with a low viscous parameter α, we find that not only the viscous an...
متن کاملDoes the Slim - Disk Model Correctly Consider Photon - Trapping Effects ?
We investigate the photon-trapping effects in the super-critical black hole accretion flows by solving radiation transfer as well as the energy equations of radiation and gas. It is found that the slim-disk model generally overestimates the luminosity of the disk at around the Eddington luminosity (LE) and is not accurate in describing the effective temperature profile, since it neglects time d...
