Pulsar glitches triggered by quakes when stress reaches a threshold
Zixuan Zhou, Ruipeng Lu, Weiyang Wang +2
The starquake model of pulsar glitches is revisited in light of accumulated observational data. A statistical comparison between the time-predictable and the magnitude-predictable…
Pulsar anti-glitches: starquakes driven by magnetism?
Hanyuan Long, Ruipeng Lu, Weiyang Wang +4
In the conventional starquake model of pulsar glitches, it is usually assumed that such events arise from fault slip induced by the self-gravity of compact objects. This inevitably…
EOS-dependent millihertz quasi-periodic oscillation in low-mass X-ray binary
Helei Liu, Yong Gao, Zhaosheng Li +4
We studied the frequency and critical mass accretion rate of millihertz quasi-periodic oscillations (mHz QPOs) using a one-zone X-ray burst model. The surface gravity is specified…
Continuous gravitational waves from trapped magnetar ejecta and the connection to glitches and antiglitches
Garvin Yim, Yong Gao, Yacheng Kang +2
Gravitational waves from isolated sources have eluded detection so far. The upper limit of long-lasting continuous gravitational wave emission can now probe physically-motivated mo…
A radio pulsar phase from SGR J1935+2154 provides clues to the magnetar FRB mechanism
Weiwei Zhu, Heng Xu, Dejiang Zhou +34
The megajansky radio burst, FRB 20200428, and other bright radio bursts detected from the Galactic source SGR J1935+2154 suggest that magnetars can make fast radio bursts (FRBs), b…
Revise thermal winds of remnant neutron stars in gamma-ray bursts
Shuang Du, Tingting Lin, Shujin Hou +1
It seems that the wealth of information revealed by the multi-messenger observations of the binary neutron star (NS) merger event, GW170817/GRB 170817A/kilonova AT2017gfo, places i…
Pulsar discovery prospect of FASTA
Mengyao Xue, Weiwei Zhu, Xiangping Wu +2
The Five-hundred-meter Aperture Spherical radio Telescope (FAST) has discovered more than 650 new pulsars, which account for 20% of our known Galactic pulsar population. In this pa…
High-altitude Magnetospheric Emissions from Two Pulsars
Mao Yuan, Weiwei Zhu, Michael Kramer +21
We discover three new weak pulse components in two known pulsars, one in PSR J0304+1932 and two in PSR J1518+4904. These components are emitted about half way between the main emis…
Searching for the nano-Hertz stochastic gravitational wave background with the Chinese Pulsar Timing Array Data Release I
Heng Xu, Siyuan Chen, Yanjun Guo +24
Observing and timing a group of millisecond pulsars (MSPs) with high rotational stability enables the direct detection of gravitational waves (GWs). The GW signals can be identifie…
Radial and Non-Radial Oscillations of Inverted Hybrid Stars
Chen Zhang, Yudong Luo, Hong-bo Li +2
We study the radial and non-radial oscillations of Cross stars (CrSs), i.e., stars with a quark matter crust and a hadronic matter core in an inverted order compared to conventiona…
The precursor of GRB211211A: a tide-induced giant quake?
Enping Zhou, Yong Gao, Yurui Zhou +8
The equilibrium configuration of a solid strange star in the final inspiral phase with another compact object is generally discussed, and the starquake-related issue is revisited,…
Free Energy of Anisotropic Strangeon Stars
Shichuan Chen, Yong Gao, Enping Zhou +1
Can pulsar-like compact objects release further huge free energy besides the kinematic energy of rotation? This is actually relevant to the equation of state of cold supra-nuclear…
Rescaling strange-cluster stars and its implications on gravitational-wave echoes
Chen Zhang, Yong Gao, Cheng-Jun Xia +1
Solid states of strange-cluster matter called strangeon matter can form strangeon stars that are highly compact. We show that strangeon matter and strangeon stars can be recast int…
The FAST Galactic Plane Pulsar Snapshot Survey: II. Discovery of 76 Galactic rotating radio transients and their enigma
D. J. Zhou, J. L. Han, Jun Xu +15
We are carrying out the GPPS survey by using the FAST, the most sensitive systematic pulsar survey in the Galactic plane. In addition to about 500 pulsars already discovered throug…
Broadband X-ray timing and spectral characteristics of the accretion-powered millisecond X-ray pulsar MAXI J1816195
Zhaosheng Li, Lucien Kuiper, Mingyu Ge +11
We studied the broadband X-ray timing and spectral behaviors of the newly confirmed accreting millisecond X-ray pulsar MAXI J1816195 during its 2022 outburst. We used the data f…
Quakes of Compact Stars
Ruipeng Lu, Han Yue, Xiaoyu Lai +3
Glitches are commonly observed for pulsars, which are explained by various mechanisms. One hypothesis attributes the glitch effect to the instantaneous moment of inertia change of…
Polarisation of magnetospheric curvature radiation in repeating fast radio bursts
Wei-Yang Wang, Jin-Chen Jiang, Kejia Lee +2
Fast radio busts (FRBs) can exhibit a wide variety of polarisation properties, not only between sources but also from burst to burst for a same one. In this work, we revisit the po…
FAST observations of an extremely active episode of FRB 20201124A: III. Polarimetry
Jin-Chen Jiang, Wei-Yang Wang, Heng Xu +26
As the third paper in the multiple-part series, we report the statistical properties of radio bursts detected from the repeating fast radio burst (FRB) source FRB 20201124A with th…
An X-Ray-dim "Isolated'' Neutron Star in a Binary?
Jie Lin, Chunqian Li, Weiyang Wang +13
We report the discovery of a dark companion to 2MASS J15274848+3536572 with an orbital period of 6.14 hr. Combining the radial velocity from LAMOST observations and modelling of th…
The radio signal of PSR B0950+08 is detected over the whole pulse phase
Zhengli Wang, Jiguang Lu, Jinchen Jiang +4
Pulsars are the "lighthouses" in the universe. Periodic pulses with the duty-cycle ~10% are detected when the radio beam of the rotating pulsar sweeps across the telescope. In this…
Radio pulsations from a neutron star within the gamma-ray binary LS I +61 303
Shan-Shan Weng, Lei Qian, Bo-Jun Wang +9
LS I +61 303 is one of the rare gamma-ray binaries, emitting most of their luminosity in photons with energies beyond 100 MeV. The 26.5 d orbital period is clearly…
Repeating Fast Radio Burst: Coherent Circular Polarization By Bunches
Wei-Yang Wang, Jin-Chen Jiang, Jiguang Lu +5
Fast radio bursts (FRBs) are millisecond-duration signals that are highly dispersed at distant galaxies. However, the physical origin of FRBs is still unknown. Coherent curvature e…
Investigating magnetically-induced distortions of neutron stars through gamma-ray burst X-ray plateaus
Tingting Lin, Shuang Du, Weihua Wang +2
Magnetic field may distort neutron stars (NSs), but its effect has not been robustly tested through gravitational-wave observation yet due to the absence of a fast rotating Galacti…
Re-detection and a Possible Time Variation of Soft X-ray Polarisation from the Crab
Hua Feng, Hong Li, Xiangyun Long +24
The Crab nebula is so far the only celestial object with a statistically significant detection in soft x-ray polarimetry, a window that has not been explored in astronomy since the…
