- W2344810892 abstract "Astronomical observations reveal a gap in the mass spectrum of relativistic objects: neither black holes nor neutron stars having masses in the range of 2 - 5$,MSun$ have ever been observed. Based on the solution of the TOV equation modified to include a universal scalar field $cal{H},$ we argue that all moderate and massive neutron stars should end invisible dark energy objects (DEOs). Triggered by the $cal{H}-$baryonic matter interaction, a phase transition from normal compressible nuclear matter into an incompressible quark-superfluid is shown to occur at roughly $3$ times the nuclear density. At the transition front, the scalar field is set to inject energy at the maximum possible rate via a non-local interaction potential $V_phi = a_0 r^2 + b_0.$ This energy creates a global confining bag, inside which a sea of freely moving quarks is formed in line with the asymptotic freedom of quantum chromodynamics. The transition front, $r_f,$ creeps from inside-to-outside to reach the surface of the object on the scale of Gyrs or even shorter, depending on its initial compactness. Having $r_f$ reached $R_star,$ then the total injected dark energy via $V_phi $ turns NSs into invisible DEOs. While this may provide an explanation for the absence of stellar BHs with $M_{BH}leq 5 MSun$ and NSs with $M_{NS}geq 2 MSun$, it also suggests that DEOs might have hidden connection to dark matter and dark energy in cosmology." @default.
