چکیده
Abstract We consider the accretion process in thin disk around a supermassive black hole Einstein-aether-scalar theory. probe effects of model parameter on physical properties disk. The results show that with increasing value parameter, energy flux, radiation temperature, spectra cut-off frequency, luminosity, and conversion efficiency decrease. is hotter more luminous than general relativity for negative while it cooler less positive parameter. also find some values allowed by theory are excluded

Black Holes in Einstein-Aether Theory
We study black hole solutions in general relativity coupled to a unit timelike vector field dubbed the “aether”. To be causally isolated a black hole interior must trap matter fields as well as all aether and metric modes. The theory possesses spin-0, spin1, and spin-2 modes whose speeds depend on four coupling coefficients. We find that the full three-parameter family of local spherically symm...
متن کاملSporadically Torqued Accretion Disks Around Black Holes
The assumption that black hole accretion disks possess an untorqued inner boundary, the so-called zero torque boundary condition, has been employed by models of black hole disks for many years. However, recent theoretical and observational work suggests that magnetic forces may appreciably torque the inner disk. This raises the question of the effect that a time-changing magnetic torque may hav...
متن کاملFive ideas on black hole accretion disks
I review five of Bohdan Paczyński’s ideas on black hole accretion disk theory. They formed my understanding of the subject and often guided intuition in my research. They are fundamentally profound, rich in physical consequences, mathematically elegant and clever, and in addition are useful in several technically difficult practical applications.
متن کاملEinstein-aether Theory *
Could there be an æther after all and we have just not yet noticed it? By an “æther” of course we do not mean to suggest a mechanical medium whose deformations correspond to electromagnetic fields, but rather a locally preferred state of rest at each point of spacetime, determined by some hitherto unknown physics. Such a frame would not be determined by a circumstance such as the moon’s gravita...
متن کاملA New Equilibrium for Accretion Disks Around Black Holes
Accretion disks around black holes in which the shear stress is proportional to the total pressure, the accretion rate is more than a small fraction of Eddington, and the matter is distributed smoothly are both thermally and viscously unstable in their inner portions. The nonlinear endstate of these instabilities is uncertain. Here a new inhomogeneous equilibrium is proposed which is both therm...
