We verify candidate hypervelocity red clump stars located in the Galactic bulge that were selected based on the VVV and the Gaia DR2 data by Luna et al. To do so, we analyze data from the OGLE-IV survey: difference images and astrometric time series. We have data for 30 stars out of 34 hypervelocity candidates. We confirmed the high proper motion of only one of these stars and find out that it is a nearby one, hence, not a hypervelocity star. To sum up, we do not confirm the candidate stars as hypervelocity ones. Hence, we disprove the production rate of hypervelocity red clump stars by the central supermassive black hole provided by Luna et al.

超高速球核红丛星的验证

我们验证了位于银河核球的候选超高速红丛星，这些恒星是根据 Luna 等人的 VVV 和 Gaia DR2 数据选择的。为此，我们分析了 OGLE-IV 调查的数据：差异图像和天体测量时间序列。我们拥有 34 颗超高速候选恒星中 30 颗的数据。我们确认了其中一颗恒星的高速自行运动，并发现它是附近的一颗恒星，因此不是超高速恒星。综上所述，我们并没有确认候选恒星是超高速恒星。因此，我们反驳了 Luna 等人提供的中央超大质量黑洞产生超高速红团簇星的速率。
