论文摘要
我们报告发现从LMC碟片的东北边缘发现了5度的新扩散的恒星属结构。通过将高斯混合物模型应用于从Gaia EDR3目录中提取的严格选择的候选候选成员的样本中，通过将高斯混合模型应用于gaia Edr3目录的样本来鉴定出我们将其配音的结构。 NES填补了LMC同一区域的外部LMC磁盘与其他已知结构之间的空白，即北部潮汐臂（NTA）和东部子结构（ES）。特别值得注意的是，NES被放置在N体模拟预见到由于MW诱导的潮汐应力引起的LMC盘的区域。天空平面上的速度场表明，包括NES在内的LMC东北部分中的潮汐结构的复合物受到连贯的径向运动。需要其他数据以及广泛的动态建模，以阐明NES的起源以及与周围子结构的关系。
We report on the discovery of a new diffuse stellar sub-structure protruding for 5 degrees from the North-Eastern rim of the LMC disc. The structure, that we dub North-East Structure (NES), was identified by applying a Gaussian Mixture Model to a sample of strictly selected candidate members of the Magellanic System, extracted from the Gaia EDR3 catalogue. The NES fills the gap between the outer LMC disk and other known structures in the same region of the LMC, namely the Northern tidal arm (NTA) and the Eastern sub-structures (ES). Particularly noteworthy is that the NES is placed in a region where N-body simulations foresee a bending of the LMC disc due to tidal stresses induced by the MW. The velocity field in the plane of the sky indicates that the complex of tidal structures in the North-Eastern part of the LMC, including NES, is subject to coherent radial motions. Additional data, as well as extensive dynamical modeling, is required to shed light on the origin of NES as well as on the relationships with the surrounding substructures.
