Exoplanet science is rapidly progressing from detection of planets towards the characterization of their atmospheres and surfaces. The occultation and phase curve of an exoplanet provides key information on the planet envelope. In the proposed research project, we will investigate: 1) the potential of exoplanet occultations and phase curves at optical wavelengths for the characterization of exoplanet atmospheres; 2) how optical and infrared observations of occultations and phase curves complement each other. Our investigation will assess the joint impact of both atmospheric and non-atmospheric effects on the measurements, and our capacity to subsequently disentangle these effects. This timely effort will help maximize the diagnostics capacities of the broadband optical photometric measurements to be delivered by a few space missions within the upcoming decade.

系外行星科学正从探测行星迅速发展到表征其大气和表面。一颗系外行星的掩星和相位曲线提供了行星包络层的关键信息。在该项目中，我们将研究：1)系外行星掩星和相位曲线在光学波长上的潜力，以表征系外行星的大气；2)掩星的光学和红外观测与相位曲线如何相互补充。我们的调查将评估大气和非大气影响对测量的共同影响，以及我们随后解开这些影响的能力。这一及时的努力将有助于最大限度地提高宽带光学光度测量的诊断能力，这些测量将在未来十年内由几个空间任务提供。
