Discovery of high-frequency quasi-periodic oscillation in short-duration gamma-ray bursts
Xing Yang, Hou-Jun Lü, Jared Rice +1
Rapidly rotating newborn magnetars, which originate from binary neutron star (NS) mergers and serve as the central engines of short gamma-ray bursts (GRBs), may leave some imprints…

The X-ray re-brightening of GRB afterglow revisited: a possible signature from activity of the central engine
Zhe Yang, Hou-Jun Lü, Xing Yang +2
Long-duration gamma-ray bursts (GRBs) are thought to be from core collapse of massive stars, and a rapidly spinning magnetar or black hole may be formed as the central engine. The…

Can fallback accretion on magnetar model power the X-ray flares simultaneously observed with gamma-rays of Gamma-ray bursts?
Wen-Yuan Yu, Hou-Jun Lü, Xing Yang +2
The prompt emission, X-ray plateau, and X-ray flares of Gamma-ray bursts (GRB) are thought to be from internal dissipation, and the magnetar as the central engine with propeller fa…
