Hydrodynamical simulation of wind production from hot accretion flows in tidal disruption events
Mingjun Liu, De-Fu Bu, Xiao-Hong Yang +5
Wind is a key mechanism for supermassive black hole (SMBH) feedback to their host galaxies. In tidal disruption events (TDEs), black holes spend most of their time accreting at hig…
Accretion geometry in neutron star low-mass X-ray binaries during the hard spectral state
Emmi Meyer-Hofmeister, Yilong Wang, B. F. Liu
We investigate the accretion geometry in neutron star low-mass X-ray binaries (LMXBs) in the hard spectral state. It is commonly accepted that, for low mass transfer rates, an adve…
Accretion with two-phase gas supply and its application in black hole X-ray binaries
Yilong Wang, B. F. Liu, Mingjun Liu
Accretion in black hole X-ray binaries is commonly believed to be supplied by the Roche lobe overflow or the stellar wind. The former is thought to form a geometrically thin disc w…
The effectively optically thin accretion flow and its implication in supermassive black holes
Mingjun Liu, B. F. Liu, Yilong Wang +2
Based on a unified description of various accretion flows, we find a long-ignored solution - the effectively optically thin accretion flow, occurring at accretion rates around Eddi…
A generalized solution for advection-dominated accretion flow, standard disc, and slim disc
Mingjun Liu, B. F. Liu, Yilong Wang +2
Aiming at a general description of four basic solutions describing the accretion processes, i.e., the Shakura-Sunyaev thin disc (SSD), the Shapiro-Lightman-Eardley solution (SLE),…
A large population of neutron star low-mass X-ray binaries with long outburst recurrence time ?
E. Meyer-Hofmeister, Huaqing Cheng, B. F. Liu
Low-mass X-ray binaries (LMXBs) with neutron stars show quite different features which depend on the rate of mass transfer from the donor star. With a high transfer rate the Z sour…
