摘要
最近的高角分辨率（约0.2英寸）ALMA观测揭示了IRS 43这一二进制原恒星1.1 mm连续辐射以及HCO+ J=3-2和HCN J=3-2气体，显示出多个开普勒盘与二进制平面严格偏移（大于60度），包括倾角和位置角度。每个恒星成分都有一个相关的周绕盘，而该二进制系统被周绕盘包围。结合25年期间VLA对恒星位置的测量，假设为圆形轨道，我们利用连续辐射测量确定二进制分离度a=74±4 AU，其倾角i<30度。该系统中的偏移提示涡流动力学在IRS 43的形成中 likely 发挥了主要作用。

v2: 27 pages; minor title change; added the projective symplectic group PSp(6,5); various typo fixes; GAP code moved from an appendix into an earlier section; added in the code section that all groups of order less than 2016 (except possibly those of order 1024) have been verified as FSZ
