Global transonic solution of hot accretion flow with thermal conduction

چکیده
We examine the effect of thermal conduction on low-angular momentum hot accretion flow (HAF) around non-rotating black holes accreting mass at very low rate. While doing so, we adopt conductive heat flux in saturated form, and solve set dynamical equations corresponding to a steady, axisymmetric, viscous, advective using numerical methods. study thermodynamical properties matter terms input parameters, namely energy ($\varepsilon_0$), angular ($\ell_0$), viscosity parameter ($\alpha$), saturation constant ($\Phi_{\rm s}$) regulating conduction. find that $\Phi_{\rm s}$ plays pivotal role deciding transonic global solutions. In general, when is increased, critical point ($r_{\rm c}$) receded away from hole, variables are altered particularly outer part disc. To quantify physically acceptable range s}$, compare solutions with self-similar solutions, observe maximum ($\Phi^{\rm max}_{\rm estimated exceeds limit sc}$) derived formalism. Moreover, calculate correlation between $\alpha$ $\Phi^{\rm ample disagreement Further, variables, compute Bernoulli ($Be$) which remains positive all throughout disc, although becomes loosely unbound for higher s}$. Finally, indicate relevance this work astrophysical context explaining possibility massloss/outflows

Hot Accretion With Conduction: Spontaneous Thermal Outflows
Motivated by the low-collisionality of gas accreted onto black holes in Sgr A* and other nearby galactic nuclei, we study a family of 2D advective accretion solutions with thermal conduction. While we only impose global inflow, the accretion flow spontaneously develops bipolar outflows. The role of conduction is key in providing the extra degree of freedom (latitudinal energy transport) necessa...

The Role of Thermal Conduction in Accretion Disks with Outflows
In this work we solve the set of hydrodynamical equations for accretion disks in the spherical coordinates (r,θ,ϕ) to obtain the explicit structure along θ direction. We study a two-dimensional advective accretion disc in the presence of thermal conduction. We find self-similar solutions for an axisymmetric, rotating, steady, viscous-resistive disk. We show that the global structure of an advec...
متن کاملHot Accretion with Saturated Conduction
Observations of the hot gas surrounding Sgr A* and a few other nearby galactic nuclei imply electron and proton mean free paths comparable to the gas capture radius: hot accretion likely proceeds under weakly-collisional conditions in these systems. As a result, thermal conduction, rather than convection, may be important on all scales and affect the global flow properties. The self-similar ADA...
متن کاملThermal Conduction and the Stability of Hot Accretion Flows
Recently, Medvedev & Narayan (2001) discovered a new type of accretion flow, a hot settling flow around a rapidly rotating neutron star. The flow is cooling-dominated and energetically similar to the Shapiro, Lightman, & Eardley (1976, SLE) solution. Since the SLE solution is known to be thermally unstable, one might suspect that the new solution would also be unstable. However, due to the very...
