HAT-P-58b -- HAT-P-64b：七颗凌亮星行星
摘要
我们报告由 HATNet 巡天发现并表征的 7 颗凌星系外行星。这些行星为凌亮类太阳星的热木星与热土星，包括：HAT-P-58b（质量 Mp = 0.37 MJ、半径 Rp = 1.33 RJ、轨道周期 P = 4.0138 天）、HAT-P-59b（Mp = 1.54 MJ、Rp = 1.12 RJ、P = 4.1420 天）、HAT-P-60b（Mp = 0.57 MJ、Rp = 1.63 RJ、P = 4.7948 天）、HAT-P-61b（Mp = 1.06 MJ、Rp = 0.90 RJ、P = 1.9023 天）、HAT-P-62b（Mp = 0.76 MJ、Rp = 1.07 RJ、P = 2.6453 天）、HAT-P-63b（Mp = 0.61 MJ、Rp = 1.12 RJ、P = 3.3777 天）和 HAT-P-64b（Mp = 0.58 MJ、Rp = 1.70 RJ、P = 4.0072 天）。这些量的典型误差分别为 0.06 MJ、0.03 RJ 和 0.2 秒。我们还提供了各宿主星的精确恒星参数。HAT-P-60 的 V = 9.710+/-0.050 mag，是一颗尤其明亮的凌星行星宿主星，是额外后续观测的极佳目标。HAT-P-64b 的 Rp = 1.703+/-0.070 RJ，是一颗高度膨胀的热木星，绕一颗接近主序末期的恒星运转，属已知最大行星之列。七个系统中五个有 TESS 的长节奏观测，已纳入分析。特别值得注意的是 HAT-P-59（TOI-1826.01）位于 TESS 任务北方连续视场区内，以及 HAT-P-60 为 TESS 候选体 TOI-1580.01。
