We present a new equation of state for the nucleonic and hyperonic inner core of neutron stars that fulfills the 2 Msun observations as well as the recent determinations of stellar radii below 13 km. The equation of state is obtained from a new parametrization of the FSU2 relativistic mean-field functional that satisfies these latest astrophysical constraints and, at the same time, reproduces...

Motivated from the observations of yet-unexplained explosive phenomena associated with massive blue-supergiant stars with zero-age main sequence (ZAMS) masses well above 40 M${}_{\odot }$, we shed new light on the idea that the appearance of QCD degrees of freedom may explain such cosmic events [1]. Obeying chiral physics and taking yet-another important observation of the very existence of massive...

We study the spatial distribution of the stress tensor around the quark--anti-quark system in SU(3) lattice gauge theory. The formation of the flux tube and its detailed structure after the continuum limit is revealed in terms of the stress tensor. The Yang-Mills gradient flow plays a crucial role to realize the analysis of the stress tensor on the lattice. We also perform an analysis of the...
