High-Density Sound Speed and Post-Merger Dynamics
John Stroud, David Radice, Sanjay Reddy
The density dependence of the speed of sound in cold neutron star matter remains poorly constrained and is central to determining the high-density equation of state (EOS). While bi…

Pi in the Sky: Neutron Stars with Exceptionally Light QCD Axions
Mia Kumamoto, Junwu Huang, Christian Drischler +2
We present a comprehensive study of axion condensed neutron stars that arise in models of an exceptionally light axion that couples to quantum chromodynamics (QCD). These axions so…

The Kohn-Luttinger Effect in Dense Matter and its Implications for Neutron Stars
Mia Kumamoto, Sanjay Reddy
Repulsive short-range interactions can induce p-wave attraction between fermions in dense matter and lead to Cooper pairing at the Fermi surface. We investigate this phenomenon, we…
