论文摘要
我们着手探索如何最好地减轻过境苔丝系统的时期别名数量，其中两个确定的转移在几年的阶段被大的时间段分开。我们基于苔丝初级和扩展任务的观察策略来模拟逼真的跨越跨越行星的现实人群。接下来，我们使用光度法（NGTS）和光谱法（HARPS和CORALIE）模拟其他观察结果，并评估其对具有两个Tess Transits系统的周期别名的影响。我们发现苔丝将检测到大约400个外部球星，这些系外行星在每个主要和扩展任务中都有一个过境。根据时间覆盖，这些系统中的每一个平均都将具有38个周期的别名。我们发现，假设NGT和Coralie在观察50天的活动中结合在一起，我们可以找到真正的别名，从而解决该时期，对于多达207个系统，如果观察到的运动被扩展或我们升级到Coralie，则可以解决这些系统。
We set out to explore how best to mitigate the number of period aliases for a transiting TESS system with two identified transits separated by a large time period on the order of years. We simulate a realistic population of doubly transiting planets based on the observing strategy of the TESS primary and extended missions. We next simulate additional observations using photometry (NGTS) and spectroscopy (HARPS and CORALIE) and assess its impact on the period aliases of systems with two TESS transits. We find that TESS will detect around 400 exoplanets that exhibit one transit in each of the primary and extended missions. Based on the temporal coverage, each of these systems will have an average of 38 period aliases. We find that, assuming a combination of NGTS and CORALIE over observing campaigns spanning 50 days, we can find the true alias, and thus solve the period, for up to 207 of these systems with even more being solved if the observing campaigns are extended or we upgrade to HARPS over CORALIE.
