Abstract

The binary neutron star merger GW170817/GRB170817A confirmed that at least some neutron star mergers are the progenitors of short gamma-ray bursts. Many short gamma-ray bursts have long-term x-ray afterglows that have been interpreted in terms of post-merger millisecond magnetars - rapidly rotating, highly magnetised, massive neutron stars. We review our current understanding of millisecond magnetars born in short gamma-ray bursts, focusing particularly three main topics. First, whether millisecond magnetars really do provide the most plausible explain for the x-ray plateau. Second, determining and observing the gravitational-wave emission from these remnants. Third, determining the equation of state of nuclear matter from current and future x-ray and gravitational-wave measurements.

OtherThe Equation of State (EOS) of matter is the relationship among pressure, density, temperature and composition of the matter. To determine the EOS of dense neutron-rich nuclear matter has been a longstanding goal of both astrophysics and nuclear physics. Articles in this proceeding of the Xiamen-CUSTIPEN Workshop on the EOS of Dense Neutron-Rich Nuclear Matter in the Era of Gravitational Waves summarize the latest development in this field. The main topics include

* EOS of Neutron-Rich Matter from Nuclear Theories and Terrestrial Experiments
* Properties of Neutron Stars from Theories and Observations
* Impacts of Nuclear EOS on the Evolution Dynamics and Products of Compact Binaries
* Imprints of Nuclear EOS on Gravitational Waves from Various Sources
* Nature of Dense Matter and Synthesis of Heavy Elements in the Cosmos
* Isospin Dependence of Strong Interactions and Correlations in Dense Matter
