Radiation mechanism of twin kilohertz quasi-periodic oscillations in neutron star low mass X-ray binaries
ChangSheng Shi, GuoBao Zhang, ShuangNan Zhang +1
Context: The connection between quasi-periodic oscillations (QPOs) and magnetic fields has been investigated across various celestial bodies. Magnetohydrodynamics (MHD) waves have…
The bright black hole X-ray binary 4U 1543-47 during 2021 outburst. A clear state transition from super-Eddington to sub-Eddington accretion revealed by Insight-HXMT
Pei Jin, Guobao Zhang, Yuexin Zhang +9
We present a detailed analysis of the observations with the Hard X-ray Modulation Telescope of the black hole X-ray transient 4U~1543-47 during its outburst in 2021. We find a clea…
Insight-HXMT observations of thermonuclear X-ray bursts in 4U 1636-53
Zhe Yan, Guobao Zhang, Yu-Peng Chen +9
We conducted an analysis of 45 bursts observed from 4U 163653. To investigate the mechanism behind the light curve profiles and the impact of thermonuclear X-ray bursts on the a…
Investigation into the reflection properties of the neutron star low-mass X-ray binary 4U 1636-53
Ming Lyu, Guobao Zhang, H. G. Wang +1
We present the spectroscopy of the neutron star low-mass X-ray binary 4U 1636-53 using six simultaneous XMM-Newton and Rossi X-ray Timing Explorer observations. We applied differen…
Relation between spectral changes and the presence of the lower kHz QPO in the neutron-star low-mass X-ray binary 4U 1636-53
Guobao Zhang, Mariano Méndez, Andrea Sanna +2
We fitted the -keV spectrum of all the observations of the neutron-star low-mass X-ray binary 4U 163653 taken with the {\it Rossi X-ray Timing Explorer} using a model tha…
Millihertz quasi-periodic oscillations in 4U 1636-53 associated with bursts with positive convexity only
Ming Lyu, Mariano Mendez, Diego Altamirano +1
We investigated the convexity of all type I X-ray bursts with millihertz quasi-periodic oscillations (mHz QPOs) in 4U 1636-53 using archival observations with the Rossi X-ray Timin…
