标题： The analysis of magnetic field measurements of T Tau

摘要： 结果表明，T Tau 表面存在高温吸积斑点这一情况实际上对估算其光球层磁场强度的准确性没有影响。 我们还发现，可以以下述备选方案来解释通过不同方法对 T Tau 光球层磁场强度测量的结果：1）如果 T Tau 的倾角 $i\le 10^\circ,$，那么该恒星的磁场可能是偶极子场，其自转轴与磁轴之间的夹角约为 $85^\circ;$；2）如果（例如从干涉观测中）发现 $i>10^\circ,$，那么 T Tau 的磁场本质上是非偶极子或者/和非定常的。 显示英文摘要

摘要： It is shown that the existence of hot accretion spots at the surface of T Tau practically has no effect on the accuracy of estimation of its magnetic field strength at photospheric level. We also found that one can interpret results of T Tau's photospheric magnetic field strength measurements carried out via different methods in the frame of the following alternative: 1) if T Tau's inclination angle $i\le 10^\circ,$ then magnetic field of the star may be dipolar with the angle between rotational and magnetic axes is near $85^\circ;$ 2) if it will be found (e.g. from interferometric observations) that $i>10^\circ,$ then magnetic field of T Tau is essentially non-dipolar or/and non-stationary.
