Description

Strong radio flare events were detected in black hole X-ray binary system 4U 1543-47 by MeerKAT. In this work, we investigated X-ray observation data during these periods. Our results suggest a four-step jet cycle: (1) the accretion disk is full, (2) the inner disk becomes unstable, (3) the jet is formed, (4) the disk refills.
