论文摘要
我们评估了恒星过渡和振荡（柏拉图）在恒星太空任务上的宽带颜色过滤器，相对于球星大气表征。我们专注于超热木星和热木星，将25％和100％远离地球，低质量低密度行星放置10％和25％。我们的分析将宽带下游深度差的输入文献值（500至675nm）之间的波长间隔（以下称为蓝色）和上部（675-1125nm）宽带波长间隔（以下称为红色）进行传输，掩盖，掩盖，实线和相位曲线分析。研究了以F，G，K和M恒星类别旋转的主要序列中心星的行星。我们计算相对于光子和仪器噪声的信噪比，以检测两个光谱间隔之间的过境深度差。结果表明，对于（超）热木星，可以检测到大气组成和行星几何反照率，高达约100％（约25％），并具有强（中度）雷利灭绝。可以为超热木星的旋转K和G矮星恒星提取相位曲线信息。对于低质量低密度行星，基本的大气类型（主要和水为主导）以及在高层大气中存在亚微米危险，可以区分多达少数大约10％的情况。
We assess broadband color filters for the two fast cameras on the PLAnetary Transits and Oscillations (PLATO) of stars space mission with respect to exoplanetary atmospheric characterization. We focus on Ultra Hot Jupiters and Hot Jupiters placed 25pc and 100pc away from the Earth and low mass low density planets placed 10pc and 25pc away. Our analysis takes as input literature values for the difference in transit depth between the broadband lower (500 to 675nm) wavelength interval (hereafter referred to as blue) and the upper (675-1125nm) broadband wavelength interval (hereafter referred to as red) for transmission, occultation and phase curve analyses. Planets orbiting main sequence central stars with stellar classes F, G, K and M are investigated. We calculate the signal-to-noise ratio with respect to photon and instrument noise for detecting the difference in transit depth between the two spectral intervals. Results suggest that bulk atmospheric composition and planetary geometric albedos could be detected for (Ultra) Hot Jupiters up to about 100pc (about 25pc) with strong (moderate) Rayleigh extinction. Phase curve information could be extracted for Ultra Hot Jupiters orbiting K and G dwarf stars up to 25pc away. For low mass low density planets, basic atmospheric types (primary and water-dominated) and the presence of sub-micron hazes in the upper atmosphere could be distinguished for up to a handful of cases up to about 10pc.
