Contribution
It introduces a new equation of state for quark matter with charm impurities including a Kondo phase and analyzes its effects on star properties.
Findings
Kondo phase reduces star mass and radius
Derived EOS incorporating Kondo effects
Stars with Kondo phase are lighter and smaller
Abstract
We study light (u, d) quark matter with charm impurities. These impurities are added to the Lagrangian density. We derive the equation of state (EOS) of this kind of quark matter, which contains a Kondo phase. We explore this EOS and study the structure of stars, identifying the effects of the Kondo phase. Solving the TOV equations and computing the mass-radius diagram, we find that the presence of a Kondo phase leads to smaller and lighter stars.
