论文摘要
我们继续我们的计划发布了2021年韩国微透镜望远镜网络(KMTNET)在线数据的所有行星(以及可能的行星)的计划。我们提出了4个行星(KMT-2021-BLG-0712LB,KMT-2021-BLG-0909LB,KMT-2021-BLG-2478LB,以及KMT-2021-BLG-11105LB),具有范围-3.3 <log Q Q <-2.2的行星 - 霍斯特 - 霍斯特 - 霍斯特 - 霍斯特 - 霍斯特 - 霍斯特 - 霍斯特 - 霍斯特 - 霍斯特质量率。这使得安全,双眼,2021 kmtnet行星的总计达到16个,其中包括本系列中的8个。对半自动检测的完整性是重要的检查,这是统计分析的基础。其中一个行星KMT-2021-BLG-1115LB与可能是主机的相对明亮的$(i,v)\ sim(18.9,21.6)$ star混合在一起。这可以通过高分辨率成像立即验证。如果是这样,则宿主是早期的G矮人,地球可以以30m级望远镜上的径向速度观测为特征。
We continue our program of publishing all planets (and possible planets) found by eye in 2021 Korea Microlensing Telescope Network (KMTNet) online data. We present 4 planets, (KMT-2021-BLG-0712Lb, KMT-2021-BLG-0909Lb, KMT-2021-BLG-2478Lb, and KMT-2021-BLG-1105Lb), with planet-host mass ratios in the range -3.3 < log q < -2.2. This brings the total of secure, by-eye, 2021 KMTNet planets to 16, including 8 in this series. The by-eye sample is an important check of the completeness of semi-automated detections, which are the basis for statistical analyses. One of the planets, KMT-2021-BLG-1105Lb, is blended with a relatively bright $(I,V)\sim (18.9,21.6)$ star that may be the host. This could be verified immediately by high-resolution imaging. If so, the host is an early G dwarf, and the planet could be characterized by radial-velocity observations on 30m class telescopes.
