The next generation of space telescopes will enable transformative science to understand the nature and origin of exoplanets. In particular, transit spectroscopy will reveal the chemical composition of the exoplanet atmospheres with unprecedented detail thanks to precise measurements of the visible-to-infrared transit depths down to 10 parts per million. Such a level of instrumental precision raises the challenge to obtain even more precise astrophysical models so as not to significantly influence the interpretation of the observed data. We must therefore critically revisit some of the commonly accepted assumptions that were adequate for analyzing past and current observations. A common approximation in the analysis of exoplanetary primary transits is that the planet does not contribute to the recorded flux, so-called dark planet hypothesis. In this paper, we investigate the impact of the dark planet hypothesis on the parameters obtained from the analysis of transi...

系外行星过境深度的相曲线污染

下一代太空望远镜将使变革科学能够了解系外行星的性质和起源。尤其是，由于精确测量了可见/红外穿透深度（低至百万分之十），因此透射光谱法将以前所未有的细节揭示系外行星大气的化学成分。这样高的仪器精度水平对获得甚至更精确的天体物理模型提出了挑战，从而不会显着影响观测数据的解释。因此，我们必须批判性地重新考虑一些足以用于分析过去和当前观察结果的公认假设。在系外行星一次过境分析中，一个常见的近似值是行星对记录的通量没有贡献，即所谓的暗行星假说。
