Ill talk about prospects for constraining the spin of the massive black hole at the Galactic center via the relativistic motion of a surrounding star.By using numerical simulations of the relativistic motion of a surrounding star in a large parameter space,we address the questions on (1) how accurate the astrometric and velocity/redshift measurements are needed to provide a tight constraint on the MBH spin by using the motion of a star,e.g.,the closest one to the MBH currently detected,and (2) what is the orbital parameter space for a possibly existing star that may help to put strong constraint on the MBH spin and metric with the next generation (or future) facilities.By addressing those questions,we provide guiding maps for future observational endeavor on constraining the GC MBH spin.

大型射电天线对于卫星等的监测、维护工作至关重要,但关于如何精确测定其相位中心坐标的研究却很少.本文针对这一问题以国家授时中心昊平观测站40米口径射电天线为例,介绍了其相位中心坐标完整的测量方案、观测及资料处理情况,求得了其在CGCS2000坐标系下的坐标,精度优于8mm.并提出先测定天线旋转中心,再通过坐标转化求得相位中心的方法;采用圆曲线拟合得到旋转中心的平面坐标,并对拟合精度的影响因素进行了模

我们研究了2015年6月18日发生的一个很明显的日冕loop震荡事件,该震荡由位于loop下方的C7.2级耀斑引起.通过对耀斑上方loop震荡进行详细分析后我们发现相邻的一束loop中不同loop的震荡情况有着很大的不同,它们的周期和振幅都存在着很大的差异,比较靠上方的loop的震荡周期和振幅都接近于下方的两倍,这现象表明相邻loop的物理性质有着较大的不同;另外我们还发现同一个loop不同位置的
