Resumo
Interplay between properties of hyperonic interactions and neutron star observables is studied with Skyrme NN, ΛN, and ΛΛ potentials. It is shown that the ΛN potentials with different density dependencies, which describe Λ hypernuclear spectra equally well, lead to substantially different dependence of neutron star mass on its radius. The role of the nucleon density dependence of ΛΛ potential is considered within the Skyrme formalism at the first time. It is shown that this dependence influences the calculated masses and radii weaker.
