accretion stream造句

• Critically, this asynchronous rotation causes the accretion stream to interact with different magnetic field lines.
• They are ionized by AGN, suggesting that cold accretion streams as a power source must deplete between z = 2 and z = 0.3.
• Non-magnetic systems exhibit full accretion disks, while strongly magnetic systems ( called polars or AM Herculis systems ) exhibit only accretion streams which directly impact the white dwarf's magnetosphere.
• There is also evidence in each of the four asynchronous polars that the accretion stream is able to travel much deeper into the WD's magnetosphere than in synchronous systems, implying an unusually high rate of mass transfer from the donor star or a low magnetic field strength, but this has not been studied in detail.
