确定了具有相互作用势 V(phi) = (1/4)lambda 化学键 phi 化学键/sup 4/ 的自相互作用标量场 phi 的球对称引力平衡。令人惊讶的是，即使当 lambda<<1 时，所得配置也可能与非交互情况显着不同。与普遍接受的天体物理学民间传说相反，人们发现这种玻色子星的最大质量可能与质量为 m/sub fermion/--lambda/sup -1/4/m/sub boson/ 的费米子的钱德拉塞卡质量相当。 .AE
Spherically symmetric gravitational equilibria of self-interacting scalar fields phi with interaction potential V(phi) = (1/4)lambdachemically bondphichemically bond/sup 4/ are determined. Surprisingly, the resulting configurations may differ markedly from the noninteracting case even when lambda<<1. Contrary to generally accepted astrophysical folklore, it is found that the maximum masses of such boson stars may be comparable to the Chandrasekhar mass for fermions of mass m/sub fermion/--lambda/sup -1/4/m/sub boson/. .AE
