Effect of Hyperon Isospin Interaction on the Transition Density of Hyperon Stars
摘要
Abstract
The effect of hyperon isospin interaction on the transition density of hyperon stars was studied by means of relativistic mean field theory for the baryon octet { n ,p ,A ,∑- ,∑0 ,∑+ ,≡- ,≡0 } system. The results show that, considering the hyperon isospin interaction, the transition density of hyperon stars gradually decreased when xp∑ = 2,1,2/3. When baryonic density was the transition density of hyperon stars, the A and ≡- hyperons make the most contribution to the transition density of hyperon stars, A and ≡- hyperon populations nearly amount to 80％ of the total hyperon populations, the particle populations of ≡- decreased as xp∑ reduced, A hyperon populations were 34.2％ ,35.8％ and 33.8％ of the total hyperon populations as xp∑＝ 2,1,2/3, respectively.关键词
