Abstract

Superfluidity of Λ-hyperons admixed in neutron star cores is investigated by a realistic approach and found to be realizable with the critical temperature of 108-9 K though in a restricted density region. In reference to the results of Λ, the possible occurence of the Σ-- and Ξ-- superfluidities is pointed out. The pairing effects of hyperons is also shown to be important in hypernuclear matter relevant to hypernuclei. In a treatment of a gap equation, the necessity to use a "bare" hyperon-hyperon interaction, instead of an "effective" one, is stressed.
