Nearby, Young Moving Groups : Spatial and Kinematic Models

Here we show the Spatial and Kinematic Models that were used to represent nearby, young moving groups in the spatial XYZ and dynamical UVW parameter spaces. The distribution of bona fide members in each parameter space are represented with gaussian ellipsoids that are free to rotate along any axes. Red dots are members, the blue dot is the Sun, the 3D orange ellipsoid and its three projections are the 1.5-sigma contour of the kinematic model, green lines and pale blue dots are projections of the positions of members (red dots). See Gagné et al. (2013, submitted to ApJ) for more details.

本文展示了用于在空间XYZ与动力学UVW参数空间中表征邻近年轻移动星群的空间运动学模型。各参数空间中确证成员星的分布由可沿任意轴自由旋转的高斯椭球进行表征。红点代表成员星，蓝点代表太阳；三维橙色椭球及其三个投影为该运动学模型的1.5σ等高线，绿色线条与淡蓝色点则为成员星（红点）位置的投影。更多细节请参阅Gagné等人（2013年，投稿至ApJ）。
