多振荡玻色子星

Multi-oscillating Boson Stars

Matthew Choptuik, Ramon Masachs, Benson Way

摘要:

我们建议,稳定的玻色子星一般属于一个无限参数的家庭的解决方案,振荡的任何数量的非相称的频率。我们用数值方法构造了两个频率的解并探索了它们的参数空间。这些解决方案与标准玻色子恒星家族在非主导频率关闭的极限中合并。我们发现,对于一个固定的能量,这些两个频率的解决方案可以从标准玻色子星的大小有很大的不同。

英文摘要:

We propose that stable boson stars generically fall within an infinite-parameter family of solutions that oscillate on any number of non-commensurate frequencies. We numerically construct two-frequency solutions and explore their parameter space. These solutions merge with the standard boson star family in the limit where the non-dominating frequencies are turned off. We find that for a fixed energy, these two-frequency solutions can differ considerably in size from standard boson stars.
