Now that detection of gravitational-wave signals from the coalescence of extra-galactic
compact binary star mergers has become nearly routine, it is intriguing to consider other …

The nuclear symmetry energy characterizes the variation of the binding energy as the
neutron to proton ratio of a nuclear system is varied. This is one of the most important …

The quantum chromodynamics (QCD) axion may modify the cooling rates of neutron stars
(NSs). The axions are produced within the NS cores from nucleon bremsstrahlung and …

Supernova remnants are beautiful astronomical objects that are also of high scientific
interest, because they provide insights into supernova explosion mechanisms, and because …

We propose that the observed cooling of the neutron star in Cassiopeia A is due to
enhanced neutrino emission from the recent onset of the breaking and formation of neutron …

JCW had long wanted to write a new monograph on supernovae. Despite an immense
explosion in the literature and many review articles, there had not been one since that of …

According to recent results of Ho & Heinke, the Cassiopeia A supernova remnant contains a
young (≈ 330-yr-old) neutron star (NS) which has carbon atmosphere and shows notable …

Asymmetry is required by most numerical simulations of stellar core-collapse explosions, but
the form it takes differs significantly among models. The spatial distribution of radioactive …

Ages and thermal luminosities of neutron stars, inferred from observations, can be
interpreted with the aid of the neutron star cooling theory to gain information on the …

Powerful radio jets from active galactic nuclei are thought to be powered by the accretion of
material onto the supermassive black hole (the 'central engine'),. M87 is one of the closest …
