Strangeon Ergostars
Haojia Xia, Shichuan Chen, Hong-Bo Li +2
The nature of the central engine powering short gamma-ray bursts (sGRBs) in binary neutron star (BNS) mergers remains a key open question in the era of multi-messenger astronomy. T…
Probing phase transition in neutron stars via the crust-core interfacial mode
Jiaxiang Zhu, Chuming Wang, Chengjun Xia +2
Gravitational waves emitted from the binary neutron star (BNS) systems can carry information about the dense matter phase in these compact stars. The crust-core interfacial mode is…
Pulsar glitches in a strangeon star model. II. The activity
Weihua Wang, Xiaoyu Lai, Enping Zhou +3
Glitch is supposed to be a useful probe into pulsar's interior, but the underlying physics remains puzzling. The glitch activity may reflect a lower limit of the crustal moment of…
Uniformly rotating, axisymmetric and triaxial quark stars in general relativity
Enping Zhou, Antonios Tsokaros, Luciano Rezzolla +2
Quasi-equilibrium models of uniformly rotating axisymmetric and triaxial quark stars are computed in general relativistic gravity scenario. The Isenberg-Wilson-Mathews (IWM) formul…
Evolution of bare quark stars in full general relativity: Single star case
Enping Zhou, Kenta Kiuchi, Masaru Shibata +2
We introduce our approaches, in particular the modifications of the primitive recovery procedure, to handle bare quark stars in numerical relativity simulations. Reliability and co…
On the energy budget of starquake-induced repeating fast radio bursts
Wei-Yang Wang, Chen Zhang, Enping Zhou +7
With a growing sample of fast radio bursts (FRBs), we investigate the energy budget of different power sources within the framework of magnetar starquake triggering mechanism. Duri…
