چکیده
Some of the accreting black holes exhibit much stronger variability patterns than usual stochastic variations. Radiation pressure instability is one proposed mechanisms which could account for this effect. We aim to model luminosity changes objects with hole mass 10, 10$^5$, and 10$^7$ solar masses, using time-dependent evolution an accretion disk unstable due dominant radiation pressure. use a 1-dimensional, vertically integrated numerical scheme models simultaneous corona, coupled by vertical exchange. also discuss possibility presence inner optically thin flow, namely Advection-Dominated Accretion Flow (ADAF). found that outburst character strongly depends on magnetic field outer radius if smaller (due TDE phenomenon) size zone in stationary infinite radius. For microquasars, dependence monotonic, period decreases strength. larger non-monotonic, initial rise later replaced relatively rapid decrease as continues rise. Still stabilizes disk. Our computations confirm can heartbeat states microquasars. Rapid detected IMBH form Quasi-Periodic Ejection be consistent but only combined phenomenon. Yearly repeating Changing Look AGN requires, our model, small either recent or gap related secondary hole.

Hyper-accreting black holes
Hyper-accretion disks are short-lived, powerful sources of neutrinos and magnetized jets. Such disks are plausible sources of gamma-ray bursts. This review describes the disk structure, the neutrino conversion to electron-positron plasma around the disk, and the post-burst evolution.
متن کاملAdvection-Dominated Models of Luminous Accreting Black Holes
It has been found that a class of optically-thin two-temperature advection-dominated accretion solutions explains many observations of low-luminosity accreting black holes. Here it is shown that these models give a satisfactory description also of higher luminosity systems, provided the viscosity parameter is large. The models reproduce the spectra of black hole X-ray binaries in the Low State,...
متن کاملMergers of accreting stellar-mass black holes
We present post-Newtonian N -body simulations on mergers of accreting stellarmass black holes (BHs), where such general relativistic effects as the pericentre shift and gravitational wave emission are taken into consideration. To elucidate the key physics that regulates mergers of BHs, the dynamical friction and the mass accretion by ambient gas are incorporated. We consider a system composed o...
متن کاملSpacetime constraints on accreting black holes
We study the spin dependence of accretion onto rotating Kerr black holes using analytic techniques. In its linear regime, angular momentum transport in MHD turbulent accretion flow involves the generation of radial magnetic field connecting plasma in a differentially rotating flow. We take a first principles approach, highlighting the constraint that limits the generation and amplification of r...
