TAGO Event(Near-Field Microlensing) and Structure of the Galaxy

“TAGO事件”是第一个在近场星星中证实的微透镜现象。在银河系的标准结构中，这种现象发生的概率非常小。然而，这一现象可以用这样的想法来解释：“质量分布函数的低质量侧比标准模型的大。“从MOA小组的微透镜观测中，我们发现低质量侧的质量分布函数的值比标准模型的大两倍，这是由于发现了邻居褐矮星的微透镜和发现了“浮动行星”。这表明TAGO天体是一颗褐矮星和/或一颗浮动行星。在不久的将来，这些问题将通过自行的测量得到澄清。

The "TAGO event" is the first microlensing phenomenon confirmed in the near-field star. In a standard structure of the Galaxy, the probability that this phenomenon occurs is very small. However, it might be explained this phenomenon by thinking ; "The low mass side of the mass distribution function is larger than that of a standard model." From the microlensing observation by MOA group, we found that the value of the mass distribution function on the low mass side is twice larger than that of a standard model by discovering the microlensing due to neighborhood brown dwarf and by discovering the "floating planet". These suggest that the TAGO Object is a brown dwarf and/or a floating planet. These will be clarified by the measurement of the proper motion in the near future.
