Radiation-Regulated Spherical Accretion with an Inner Accretion Disk
Cheng-Liang Jiao, Liying Zhu, Xiang-dong Shi +1
We develop a theoretical model for radiation-regulated spherical accretion with an inner accretion disk. In our model, the outer accretion flow remains quasi-spherical and opticall…
A unified framework for hot accretion flows with finite angular momentum: from Bondi-like to disc-like regimes
Cheng-Liang Jiao, Liying Zhu, Er-gang Zhao +1
Observations of X-ray luminous elliptical galaxies suggest that the accretion rate onto the central supermassive black hole can reach a substantial fraction of the Bondi rate. Howe…
Accretion rates of stellar-mass compact objects embedded in AGN discs
Cheng-Liang Jiao, Liying Zhu, Er-gang Zhao +1
Stellar-mass compact objects (COs) embedded in active galactic nucleus (AGN) discs are commonly assumed to accrete via Bondi or Bondi-Hoyle-Lyttleton (BHL) prescriptions, neglectin…
A Scenario for Origin of Global 4 mHz Oscillations in Solar Corona
Li Xue, Cheng-Liang Jiao, Li-Xin Zhang
We establish a spherically symmetric model of solar atmosphere, which consists of the whole chromosphere and low corona below the solar radius. It is a hydrodynamic model wi…
Heating or Cooling: Study of Advective Heat Transport in the Inflow and the Outflow of Optically Thin Advection-dominated Accretion Flows
Cheng-Liang Jiao
Advection is believed to be the dominant cooling mechanism in optically thin advection-dominated accretion flows (ADAF's). When outflow is considered, however, the first impression…
Study of advective energy transport in the inflow and the outflow of super-Eddington accretion flows
Cheng-Liang Jiao
Photon trapping is believed to be an important mechanism in super-Eddington accretion, which greatly reduces the radiative efficiency as photons are swallowed by the central black…
Three-dimensional simulations of accretion flow in the progenitor of Tycho's supernova
Li Xue, Cheng-Liang Jiao, Yuan Li
We run three-dimensional numerical simulations for the accretion flow around the white dwarf (WD) in the progenitor system of Tycho's supernova (SN). The mass of the WD, mass of th…
Comparison between RHD simulation of supercritical accretion flows and steady model with outflows
Cheng-Liang Jiao, Shin Mineshige, Shun Takeuchi +1
We apply our two-dimensional (2D), radially self-similar steady-state accretion flow model to the analysis of hydrodynamic simulation results of supercritical accretion flows. Self…
The correlations between optical variability and physical parameters of quasars in SDSS Stripe 82
Wenwen Zuo, Xue-Bing Wu, Yi-Qing Liu +1
We investigate the optical variability of 7658 quasars from SDSS Stripe 82. Taking advantage of a larger sample and relatively more data points for each quasar, we estimate variabi…
On the structure of Accretion Disks with Outflows
Cheng-Liang Jiao, Xue-Bing Wu
In order to study the outflows from accretion disks, we solve the set of hydrodynamic equations for accretion disks in the spherical coordinates () to obtain the explicit stru…
Global Slim Accretion Disk Solutions Revisited
Cheng-Liang Jiao, Li Xue, Wei-Min Gu +1
We show that there exists a maximal possible accretion rate, beyond which global slim disk solutions cannot be constructed because in the vertical direction the gravitational force…
