摘要
我利用2023年观测到的TESS第71和72扇区的数据，介绍了热木星WASP-12b的新凌日和掩星定时测量结果。通过首次使用全相位曲线拟合，我精确地确定了凌日和掩星的位置。我报告了 34 个新的凌日时间和特定扇区的掩星时间，将轨道衰减率更新为 -26.310 ± 0.901 ms yr-1。我的分析强烈倾向于轨道衰变模型，而不是恒定周期模型和远地点前移模型。
New Transit Timing Observations of WASP-12b from TESS Sectors 71 and 72
I present new transit and occultation timing measurements for the hot Jupiter WASP-12b using data from TESS Sectors 71 and 72, observed in 2023. Using full-phase curve fitting for the first time, I precisely locate both transits and occultations. I report 34 new transit times and sector-specific occultation times, updating the orbital decay rate to −26.310 ± 0.901 ms yr−1. My analysis strongly favors the orbital decay model over constant period and apsidal precession models.
