Redshift Dependence of the Low-energy Spectral Index of Gamma-Ray Bursts Revisited
Xiao-Li Zhang, Yong-Feng Huang, Ze-Cheng Zou
A negative correlation was found to exist between the low-energy spectral index and the redshift of gamma-ray bursts (GRBs) by Amati(2002). It was later confirmed by Geng(2013) and…
Dynamics of the clumps partially disrupted from a planet around a neutron star
Abdusattar Kurban, Xia Zhou, Na Wang +3
Tidal disruption events are common in the Universe, which may occur in various compact star systems and could account for many astrophysical phenomena. Depending on the separation…
Ultra low-mass and small-radius white dwarfs made of heavy elements
Cheng-Jun Xia, Yong-Feng Huang, Hong-Bo Li +2
Seven ultra low-mass and small-radius white dwarfs (LSPM J0815+1633, LP 240-30, BD+20 5125B, LP 462-12, WD J1257+5428, 2MASS J13453297+4200437, and SDSS J085557.46+053524.5) have b…
Possible origin of AT2021any: a failed GRB from a structured jet
Fan Xu, Yong-Feng Huang, Jin-Jun Geng
Searching for afterglows not associated with any gamma-ray bursts (GRBs) is a longstanding goal of transient surveys. These surveys provide the very chance of discovering the so-ca…
Gluon Condensation Signature in the GeV Gamma-Ray Spectra of Pulsars
Ze-Cheng Zou, Yong-Feng Huang, Cheng-Ming Li +2
The accumulation of gluons inside nucleons, i.e., the gluon condensation, may lead to a characteristic broken power-law gamma-ray spectrum in high-energy nucleon collisions. Here w…
Repeating fast radio bursts produced by a strange star interacting with its planet in an eccentric orbit
Nurimangul Nurmamat, Yong-Feng Huang, Jin-Jun Geng +2
FRB 180916 is an important repeating fast radio burst (FRB) source. Interestingly, the activity of FRB 180916 shows a well-regulated behavior, with a period of 16.35 days. The burs…
An analytic derivation of the empirical correlations of gamma-ray bursts
Fan Xu, Yong-Feng Huang, Jin-Jun Geng +3
Empirical correlations between various key parameters have been extensively explored ever since the discovery of gamma-ray bursts (GRBs) and have been widely used as standard candl…
Distribution of gamma-ray bursts on the t90-hardness ratio plane and their classification revisited
Liang Zhang, Juan-Juan Luo, Yong-Feng Huang +2
Using four mixed bivariate distributions (Normal distribution, Skew-Normal distribution, Student distribution, Skew-Student distribution) and bootstrap re-sampling analysis, we ana…
Gravitational Waves from Strange Star Core-Crust Oscillation
Ze-Cheng Zou, Yong-Feng Huang, Xiao-Li Zhang
According to the strange quark matter hypothesis, pulsars may actually be strange stars composed of self-bound strange quark matter. The normal matter crust of a strange star, unli…
The study of nonstrange quark stars within a modified NJL model
Cheng-Ming Li, Shu-Yu Zuo, Ya-Peng Zhao +2
In this work, a modified Nambu-Jona-Lasinio (NJL) model with proper-time regularization is employed to study the structure of nonstrange quark stars. The coupling constant of four-…
Neutrino Rocket Jet Model: An Explanation of High-velocity Pulsars and their Spin-down Evolution
Zheng Li, Qiu-He Peng, Miao Kang +4
The fact that the spatial velocity of pulsars is generally higher than that of their progenitor stars has bothered astronomers for nearly 50 years. It has been extensively argued t…
Gravitationally Lensed Orphan Afterglows of Gamma-Ray Bursts
Hao-Xuan Gao, Jin-Jun Geng, Lei Hu +7
The cosmological nature of gamma-ray bursts (GRBs) implies that a small portion of them could be gravitationally lensed by foreground objects during their propagation. The gravitat…
Hybrid stars and QCD phase transition with a NJL-like model
Bing-Jun Zuo, Yong-Feng Huang, Hong-Tao Feng
In this paper, we introduce a self-consistent mean field approximation to study the QCD phase transition and the structure of hybrid stars within the framework of NJL model. In our…
Searching For Strange Quark Planets
Xu Wang, Yong-Feng Huang, Bing Li
Strange quark matter (SQM) may be the true ground state of matter. According to this SQM hypothesis, the observed neutron stars actually should all be strange quark stars. But dist…
Is the Birth of PSR J0538+2817 Accompanied by a Gamma-ray Burst?
Fan Xu, Jin-Jun Geng, Xu Wang +2
Recently, the Five-hundred-meter Aperture Spherical radio Telescope (FAST) measured the three-dimensional velocity of PSR J0538+2817 in its associated supernova remnant S147 and fo…
Evolution Patterns of the Peak Energy in the GRB Prompt Emission
Hao-Xuan Gao, Jin-Jun Geng, Yong-Feng Huang
There are two different evolution patterns of the peak energy () exhibited during the prompt emission phase of gamma-ray bursts (GRBs), i.e., hard-to-soft and intensity…
Gamma-Ray Burst in a Binary System
Ze-Cheng Zou, Bin-Bin Zhang, Yong-Feng Huang +1
Regardless of their different types of progenitors and central engines, gamma-ray bursts (GRBs) were always assumed to be standalone systems after they formed. Little attention has…
