Neutron stars and the hyperon puzzle
Isaac Vidaña
Abstract
In this work we shortly review the so-called “hyperon puzzle”, i.e. , the problem of the strong softening of the equation of state of dense matter induced by the presence of hyperons which leads to maximum masses of neutron stars incompatible with the recent observations of ∼ 2 M ⊙ millisecond pulsars. In particular, we briefly go through some of the possible solutions that have been proposed to tackle this still open problem.
