论文摘要
高度受辐照的关闭气体巨头（也称为热木星）的日子的大气吸收了事件恒星辐射的重要部分，从白天和行星的夜晚，红外波长再次重新发射。在这样的行星的过境事件中，从夜间面对观察者的夜侧的重新辐射有助于发射的恒星辐射。我们证明，当包括该行星的重新喷射热辐射时，红外区域的过境光谱会显着改变。我们通过模拟即将到来的詹姆斯·韦伯太空望远镜的不同通道的相应误差来评估热木星对过境光谱的热发射对过境光谱的影响。我们发现，相对于这些模拟数据的噪声水平具有统计学意义。因此，我们传达了一个重要信息，即在热木星的转运光谱检索模型中必须考虑行星热重新排放，以更准确地解释观察到的传输光谱。
The atmosphere on the dayside of a highly irradiated close-in gas giant (also known as a hot Jupiter) absorbs a significant part of the incident stellar radiation which again gets re-emitted in the infrared wavelengths both from the day and the night sides of the planet. The re-emitted thermal radiation from the night side facing the observers during the transit event of such a planet contributes to the transmitted stellar radiation. We demonstrate that the transit spectra at the infrared region get altered significantly when such re-emitted thermal radiation of the planet is included. We assess the effects of the thermal emission of the hot Jupiters on the transit spectra by simulating observational spectroscopic data with corresponding errors from the different channels of the upcoming James Webb Space Telescope. We find that the effect is statistically significant with respect to the noise levels of those simulated data. Hence, we convey the important message that the planetary thermal re-emission must be taken into consideration in the retrieval models of transit spectra for hot Jupiters for a more accurate interpretation of the observed transit spectra.
