论文摘要
提出了涵盖7年时间的机器人望远镜网络的43个热木星系外行星HAT-P-32B的完整转移。与该系统的最新胚层相比，中期时间的精度从3.0分钟的预测模型中产生了根平方值。基于Exofast建模的估计系统参数与NASA系外行星档案中列出的默认参数值的参数大致一致。 2.15000815 +/- 0.00000013 d和2458881.71392 +/- 0.00027 BJDDTDB的更新轨道周期与使用较大望远镜的系统的最新研究一致。使用此更新的埃弗默里斯（Ephemeris），与发现埃弗默里斯（Ephemeris）相比，NASA JWST任务在2021年中期，NASA JWST任务在2021年中期对HAT-P-32B进行概念性观察的预测时间提高了1.4分钟，并且更精确。同样，ESA Ariel Mission在2020年进行观察的中期时间也提高了1.7分钟。因此，微型望远镜和其他小型望远镜的其他用户对跨行星的观察可以有助于维持目标的临时范围，以实现未来的基于空间的望远镜任务。我们还注意到，HAT-P-32田间恒星之一是ΔScuti脉动变量，并且使用与本研究相同的观测值进行表征，进一步证明了Micro-observatory在观察恒星变异性的情况下的实用性，同时观察到epphemeris维护的exoplanets进行了交易。
Observations of 43 complete transits of the hot Jupiter exoplanet HAT-P-32b using the MicroObservatory 0.15-m robotic telescope network covering a period of 7 years are presented. Compared with the most recent ephemeris for the system, the precision of the mid-transit times yielded a root-mean-square value from the predicted model of 3.0 min. The estimated system parameters based on EXOFAST modelling are broadly consistent with those of the default parameter values listed in the NASA Exoplanet Archive. An updated orbital period of 2.15000815 +/- 0.00000013 d and ephemeris of 2458881.71392 +/- 0.00027 BJDTDB is consistent with recent studies of the system using larger telescopes. Using this updated ephemeris, the predicted mid-transit time for a notional observation of HAT-P-32b by the NASA JWST mission in mid-2021 is improved by 1.4 min compared with the discovery ephemeris and is ~8 times more precise. Likewise, the mid-transit time for an observation by the ESA ARIEL mission in 2020 is improved by 1.7 min. Thus, observations of transiting exoplanets by MicroObservatory and other users of small telescopes can contribute to the maintenance of the ephemerides of targets for future space-based telescope missions. We also note that one of the HAT-P-32 field stars is a δ Scuti pulsating variable and that characterization using the same observations as this study further demonstrates the utility of MicroObservatory for the observation of stellar variability, whilst simultaneously observing transiting exoplanets for ephemeris maintenance.
