We present new observations of the active star formation region NGC 1333 in the Perseus molecular cloud complex from the James Clerk Maxwell Telescope B-Fields In Star-forming Region Observations (BISTRO) survey with the POL-2 instrument. The BISTRO data cover the entire NGC 1333 complex (∼1.5 pcנ2 pc) at 0.02 pc resolution and spatially resolve the polarized emission from individual filamentary structures for the first time. The inferred magnetic field structure is complex as a whole, with each individual filament aligned at different position angles relative to the local field orientation. We combine the BISTRO data with low- and high- resolution data derived from Planck and interferometers to study the multiscale magnetic field structure in this region. The magnetic field morphology drastically changes below a scale of ∼1 pc and remains continuous from the scales of filaments (∼0.1 pc) to that of protostellar envelopes (∼0.005 pc or ∼1000 au). Finally, we construct simple models in which we assume that the magnetic field is always perpendicular to the long axis of the filaments. We demonstrate that the observed variation of the relative orientation between the filament axes and the magnetic field angles are well reproduced by this model, taking into account the projection effects of the magnetic field and filaments relative to the plane of the sky. These projection effects may explain the apparent complexity of the magnetic field structure observed at the resolution of BISTRO data toward the filament network.

JCMT BISTRO 调查:与 NGC 1333 中细丝网络相关的磁场

我们展示了詹姆斯克拉克麦克斯韦望远镜B对英仙座分子云复合体中活动恒星形成区 NGC 1333 的新观测结果- 使用 POL-2 仪器进行的恒星形成区观测 (BISTRO) 调查中的场。BISTRO 数据以 0.02 pc 的分辨率覆盖了整个 NGC 1333 复合体(~1.5 pcנ2 pc),并首次在空间上解析了单个丝状结构的极化发射。推断的磁场结构整体上是复杂的,每个单独的细丝相对于局部磁场方向以不同的位置角度对齐。我们将 BISTRO 数据与来自普朗克和干涉仪的低分辨率和高分辨率数据相结合,研究该区域的多尺度磁场结构。磁场形态在~1 pc 的尺度以下急剧变化,并且从细丝尺度(~0.1 pc)到原恒星包膜尺度(~0.005 pc 或~1000 au)保持连续。最后,我们构建了简单的模型,其中我们假设磁场总是垂直于灯丝的长轴。我们证明,考虑到磁场和灯丝相对于天空平面的投影效应,该模型很好地再现了观察到的灯丝轴和磁场角之间相对方向的变化。这些投影效应可以解释在 BISTRO 数据分辨率下观察到的针对灯丝网络的磁场结构的明显复杂性。考虑到磁场和灯丝相对于天空平面的投影效果。这些投影效应可以解释在 BISTRO 数据分辨率下观察到的针对灯丝网络的磁场结构的明显复杂性。考虑到磁场和灯丝相对于天空平面的投影效果。这些投影效应可以解释在 BISTRO 数据分辨率下观察到的针对灯丝网络的磁场结构的明显复杂性。
