论文摘要
在这项研究中，我们通过提出一种使用开普勒（K2）光曲线来检测出可极月亮的新方法来扩展对极性行星外行星研究的讨论。我们通过比较了NASA系外行星档案中分类的〜5000个主要序列星的过境光曲线数据来塑造了这一研究，射电星系动物园系外电子探索者和系外行星随后的观察程序，该程序是收集和分析补充K2数据的存储库。通过检查K2光曲线，对与Transit相关的各种特征进行了建模，然后将其与已确认的可变性行星，可变的恒星，诸如远程二进制的变化恒星以及数据中的噪声或间隙进行了比较。为了说明，在两个单独的转移的时间安排中，2MASS J08251369+1425306（rs〜0.346）在光子通量中产生了两种特征下降，随后两次增加，推断出存在外星星球（RP 〜0.0129）及其伴侣（RP 〜0.0129）及其伴侣，及其extras extras arras arlas arlas arlas arlas armor（rm mm〜0.0044）。为了检验我们的假设，我们仔细审查了各种竞争假设，以解决二人光子通量的来源，即麦克劳克林效应，肢体变暗，多台球系统或一个在恒星表面上掩盖一个或多个日光的行星。但是，我们在K2中没有发现任何类似的光曲线，以适合竞争的假设并解释了所提出的外伴侣。
In this study, we expand the discussion of extrasolar planetary research by proposing a new approach to detecting extrasolar moons using Kepler (K2) light curves. We shaped this investigation by comparing transit light curve data of ~5000 main-sequence stars cataloged in the NASA Exoplanet Archive, the Radio Galaxy Zoo Exoplanet Explorers and the Exoplanet Follow Up Observing Program, which served as the repository to collect and analyze supplementary K2 data. By examining K2 light curves, various characteristics related to transits were modeled, which we then compared with confirmed extrasolar planets, variable stars such as eclipsing binaries and noise or gaps in the data. For illustration, perturbations in the timing of two separate transits for 2MASS J08251369+1425306 (Rs ~ 0.346) produced two characteristic decreases in the photon flux followed by two increases, inferring the presence of an extrasolar planet (Rp ~ 0.0129) and its companion, an extrasolar moon (Rm ~ 0.0048). To test our hypothesis, we scrutinized various competing assumptions to resolve the source of the duo photon flux, namely the Rossiter McLaughlin effect, limb darkening, a multiplanet system or a planet occulting one or more sunspots on the surface of the star. However, we uncovered no analogous light curve in K2 to fit the competing hypotheses and account for the proposed extrasolar companion.
