Tidal deformation and strain accumulation of solid compact stars
Hongxiang Shen, Yong Gao, Hong-Bo Li +1
The tidal deformability of compact stars encodes the equation of state of dense matter, and gravitational-wave observations such as GW170817 have begun to constrain it under the as…
Asteroseismology of neutron stars with both hyperons and resonances
Hao Sun, Jia-Xing Niu, Yong Gao +2
Employing various relativistic energy density functionals for nucleon-nucleon interactions, we investigate the impact of hyperons and resonances on the frequencies of non-radia…
Prospects for detecting neutron star-white dwarf mergers with decihertz gravitational-wave observatories
Yacheng Kang, Chang Liu, Jin-Ping Zhu +6
Based on different neutron star-white dwarf (NS-WD) population models, we investigate the prospects of gravitational-wave (GW) detections for NS-WD mergers, with the help of early…
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…
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…
A tight universal relation between the shape eccentricity and the moment of inertia for rotating neutron stars
Yong Gao, Lijing Shao, Jan Steinhoff
Universal relations that are insensitive to the equation of state (EoS) are useful in reducing the parameter space when measuring global quantities of neutron stars (NSs). In this…
Precession of magnetars: dynamical evolutions and modulations on polarized electromagnetic waves
Yong Gao, Lijing Shao, Gregory Desvignes +3
Magnetars are conjectured to be highly magnetized neutron stars (NSs). Strong internal magnetic field and elasticity in the crust may deform the stars and lead to free precession.…
Precession of triaxially deformed neutron stars
Yong Gao, Lijing Shao
A deformed neutron star (NS) will precess if the instantaneous spin axis and the angular momentum are not aligned. Such a precession can produce continuous gravitational waves (GWs…
Triaxially-deformed Freely-precessing Neutron Stars: Continuous electromagnetic and gravitational radiation
Yong Gao, Lijing Shao, Rui Xu +3
The shape of a neutron star (NS) is closely linked to its internal structure and the equation of state of supranuclear matters. A rapidly rotating, asymmetric NS in the Milky Way u…
Multiband Observation of LIGO/Virgo Binary Black Hole Mergers in the Gravitational-wave Transient Catalog GWTC-1
Chang Liu, Lijing Shao, Junjie Zhao +1
The Advanced LIGO and Virgo detectors opened a new era to study black holes (BHs) in our Universe. A population of stellar-mass binary BHs (BBHs) are discovered to be heavier than…
