Tsallis形式论背景下ONC星的自转
On the rotation of ONC stars in the Tsallis formalism context
摘要:
投影的旋转速度的理论分布函数的Tsallis形式主义的背景下推导出来。该分布用于估计<sin i>猎户座星云云(ONC)恒星样本的平均值,与观测数据相比,结果非常好。此外,从观测到的旋转分布中得到的参数q的值加强了这个参数和星团年龄之间存在关系的想法。
英文摘要:
The theoretical distribution function of the projected rotational velocity is derived in the context of the Tsallis formalism. The distribution is used to estimate the average <sin i> for a stellar sample from the Orion Nebula Cloud (ONC), producing an excellent result when compared with observational data. In addition, the value of the parameter q obtained from the distribution of observed rotations reinforces the idea that there is a relation between this parameter and the age of the cluster.
