What does perturbative QCD really have to say about neutron stars
The implications of perturbative QCD (PQCD) calculations on neutron stars are carefully examined. While PQCD calculations above baryon chemical potential $\mu_B\sim2.4$ GeV demonstrate the potential of ruling out a wide […]

Dwarf (Twin) Neutron Stars I: Did GW170817 Involve One?
Dwarf neutron stars are stable twins of neutron stars but with a maximum mass less than that of neutron stars. Their existence brings into concordance the seemingly conflicting information on […]

Turbulence modelling in neutron star merger simulations
Observations of neutron star mergers have the potential to unveil detailed physics of matter and gravity in regimes inaccessible by other experiments. Quantitative comparisons to theory and parameter estimation require […]

What if GW190425 did not produce a black hole promptly?
It is widely believed that the binary neutron star merger GW190425 produced a black hole promptly upon merger. Motivated by the potential association with the fast radio burst FRB 20190425A, […]

Geometric and thermodynamic characterization of binary neutron star accretion discs
Accretion disks formed in binary neutron star mergers play a central role in many astrophysical processes of interest, including the launching of relativistic jets or the ejection of neutron-rich matter […]
