Evidence for the photoionization absorption edge in a photospheric radius expansion X-ray burst from GRS 1747312 in Terzan 6
Zhaosheng Li, Valery F. Suleimanov, Juri Poutanen +4
Thermonuclear X-ray bursts on the surface of neutron stars (NSs) can enrich photosphere with metals, which may imprint the photoionization edges on the burst spectra. We report her…
Simultaneous constraints on the mass and radius of Aql X-1 from quiescence and X-ray burst observations
Zhaosheng Li, Maurizio Falanga, Li Chen +2
The measurement of neutron star mass and radius is one of the most direct way to distinguish between various dense matter equations of state. The mass and radius of accreting neutr…
The optical/UV excess of X-ray dim isolated neutron star: I. bremsstrahlung emission from a strangeon star plasma atmosphere
Weiyang Wang, Jiguang Lu, Hao Tong +4
X-ray dim isolated neutron stars (XDINSs) are characterized by Planckian spectra in X-ray bands, but show optical/ultraviolet(UV) excesses which are the measured photometry exceedi…
Constraints on the mass and radius of neutron stars from X-ray observations
Zhaosheng Li
This article gives a very brief introduction about measuring the mass and radius of neutron star from X-ray observations. The masses and radii of neutron stars can be determined fr…
An Ultra Low Mass and Small Radius Compact Object in 4U 1746-37?
Zhaosheng Li, Zhijie Qu, Li Chen +3
Photospheric radius expansion (PRE) bursts have already been used to constrain the masses and radii of neutron stars. RXTE observed three PRE bursts in 4U 1746-37, all with low tou…
The accretion rate independence of horizontal branch oscillation in XTE J1701-462
Zhaosheng Li, Li Chen, Jinlu Qu +3
We study the temporal and energy spectral properties of the unique neutron star low-mass X-ray binary XTE J1701-462. After assuming the HB/NB vertex as a reference position of accr…
The short bursts in SGR 1806-20, 1E 1048-5937 and SGR 0501+4516
Zhijie Qu, Zhaosheng Li, Yupeng Chen +4
We analyzed temporal and spectral properties, focusing on the short bursts, for three anomalous X-ray pulsars (AXPs) and soft gamma repeaters (SGRs), including SGR 1806-20, 1E 1048…
The Spontaneous Generation of Magnetic Moment of Beryllium Dimer on Graphene
Xiang He, Zhao-Xu Chen, Zhaosheng Li +1
Graphene has various potential applications in electronics and scientists are seeking to introduce magnetic properties on graphene. Here we report our theoretical findings that a l…
