Quark matter with strong magnetic field and possibility of the third family of compact stars.

SOTANI H. and TATSUMI T.

Abstract (from CDS):

We consider the possibility for the existence of the third family of compact objects, considering the effect of strong magnetic fields inside the hybrid stars. As a result, we demonstrate such new sequences of stable equilibrium configurations for some hadronic equations of state. Through the analysis of the adiabatic index inside stars, we find the conditions for appearing the third family of compact objects, i.e. for hadronic stars without quarks, that the maximum mass should be small, the central density for the maximum mass should be also small, and the radius for the maximum mass should be large. Even for soft hadronic equations of state, the two solar-mass stars might survive as the third family of compact objects, once quark matter with strong magnetic field, such as ∼O(1019  G), is taken into account. It might give a hint to solve the so-called hyperon puzzle in nuclear physics.
