论文摘要
恒星天生具有磁场，但其初始场强的分布仍然不确定。我们将观察结果与磁场演化的理论模型相结合，以推断1.6-3.4 m $ _ {\ odot} $的AB恒星的磁场初始分布。我们测试了各种形状不同的分布，发现平均值为$ \ sim $ 800 g和$ \ sim $ 600 g的分布与观察到的强磁性恒星的分数最为一致。我们最喜欢的分布是一种高斯，平均$ $ $ = 770 g，标准偏差为$σ$ = 146 G。测量典型场强的独立方法表明，典型的野外强度的值更接近2-3 kg，这一差异可能暗示质量依赖性和双峰初始田地分布，或者是这些磁性磁性领域的替代性理论图片。
Stars are born with magnetic fields, but the distribution of their initial field strengths remains uncertain. We combine observations with theoretical models of magnetic field evolution to infer the initial distribution of magnetic fields for AB stars in the mass range of 1.6 - 3.4 M$_{\odot}$. We tested a variety of distributions with different shapes and found that a distribution with a mean of $\sim$800 G and a full width of $\sim$600 G is most consistent with the observed fraction of strongly magnetized stars as a function of mass. Our most-favored distribution is a Gaussian with a mean of $μ$ = 770 G and standard deviation of $σ$ = 146 G. Independent approaches to measure the typical field strength suggest values closer to 2 - 3 kG, a discrepancy that could suggest a mass-dependent and bimodal initial field distribution, or an alternative theoretical picture for the origin of these magnetic fields.
