1. Binary Neutron Star System

   Linked via "merger"

   Tidal Effects and the Equation of State (EoS)
   While standard models treat the neutron stars as perfect geodesic travelers, the extreme pressures near the periastron cause significant tidal deformation, especially if the stars are not maximally rigid. Neutron stars possess an internal structure defined by their Equation of State (EoS), which describes the pressure-density relationship within the [degenerate matter](/entries…

2. Binary Neutron Star System

   Linked via "merger"

   Electromagnetic Counterparts
   The inspiral culminates in a merger, an event hypothesized to power short Gamma-Ray Bursts (sGRBs). The merger ejects neutron-rich material, which undergoes rapid neutron capture (the r-process), synthesizing elements heavier than iron, such as gold and platinum, in a transient event called a kilonova. The spectral signature of kilonovae is characterized by ra…

3. Critical Point

   Linked via "neutron star mergers"

   In high-energy physics, the concept of a critical point emerges in the context of Quantum Chromodynamics ($\text{QCD}$) [2]. Here, the critical point lies on the boundary between the confined, chirally broken phase (normal hadronic matter) and the deconfined, chirally restored phase (quark-gluon plasma).
   The spontaneous breaking of chiral symmetry ($\langle \bar{\psi} \psi \rangle \neq 0$) is …

4. Gamma Ray

   Linked via "binary neutron stars"

   Gamma-Ray Bursts (GRBs)
   GRBs are transient astronomical event characterized by an intense burst of gamma radiation lasting from milliseconds to several minutes. Long-duration GRBs (lasting $>2$ seconds) are generally associated with the core-collapse supernova of massive, rapidly rotating stars (collapsars). Short-duration GRBs (lasting $<2$ seconds) are strongly correlated with the merger of compact objects, such as [binary neutron stars](/entri…

5. Hadronic Jet

   Linked via "neutron star merger"

   Parton Showering and Scaling Anomalies
   The theoretical description of the shower evolution, typically modeled using iterative branching probabilities, exhibits a subtle dependence on the ambient local time dilation factor, $\gammat$. Specifically, experimental observations suggest that the fragmentation scale, $Q0$, responsible for initiating hadronization, is inversely proportional to the square root of the local magnetic permeability ($\mu_0$) of the vacuum…
