Formation of Binary Millisecond Pulsars with Helium White Dwarfs in a New Magnetic Braking Prescription
Xing-Peng Yang, Wen-Cong Chen
Magnetic braking (MB) mechanism plays a vital role throughout the evolution of low-mass X-ray binaries (LMXBs). Considering the standard MB prescription, the initial orbital period…
Orbital-period Changes of Low-mass X-ray Binaries Driven by Magnetic Braking
Yun-Ning Fan, Yong Shao, Wen-Cong Chen
The magnetic braking (MB) plays an important role in driving the evolution of low-mass X-ray binaries (LMXBs). The modified MB prescription, convection and rotation boosted (CARB)…
An alternative model for the orbital decay of M82 X-2: the anomalous magnetic braking of a Bp star
Wen-Cong Chen
Recently, the first pulsating ultraluminous X-ray source M82 X-2 was reported to be experiencing a rapid orbital decay at a rate of $\dot{P}=-(5.69\pm0.24)\times 10^{-8}~\rm s\,s^{…
An Alternative Channel to Black Hole Low-Mass X-ray Binaries: Dynamical Friction of Dark Matter?
Ke Qin, Wen-Cong Chen
Both the anomalous magnetic braking of Ap/Bp stars and the surrounding circumbinary disk models can account for the formation of black hole (BH) low-mass X-ray binaries (LMXBs), wh…
