论文摘要
我们添加了恒星大气和光谱建模的色度+套件，可以代码能够合成外观行驶穿着的灯罩的能力，用于任意大小的行星，最多可占主机恒星半径的10％，任意行星和恒星质量和轨道质量和轨道半径（从而确定轨道上的偏态）和仲裁或仲裁或仲裁。灯曲面是原位计算的，与从恒星表面出现的辐射场的辐射转移溶液集成，并且没有肢体变形的参数化。对Johnson-Bessel光度计系统Ubvrihjk计算的Lightcurves。我们描述了我们计算过境路径的方法，以及由掩星引起的通量减少，并将我们的灯曲线与分析溶液与四参数肢体变形参数化，以使地球在太阳中边缘过境的情况下。该功能已添加到所有端口和变化中，包括Python端口，Chromastarpy，以及在完全行列的ATLAS9表面强度分布Chromastaratlas中插值的版本。所有代码均可在www.ap.smu.ca/openstars和github（github.com/sevenian3）访问。
We have added to the Chroma+ suite of stellar atmosphere and spectrum modelling codes the ability to synthesize the exo-planet transit lightcurve for planets of arbitrary size up to 10% of the host stellar radius, and arbitrary planetary and stellar mass and orbital radius (thus determining orbital velocity) and arbitrary orbital inclination. The lightcurves are computed in situ, integrated with the radiative transfer solution for the radiation field emerging from the stellar surface, and there is no limb-darkening parameterization. The lightcurves are computed for the Johnson-Bessel photometric system UBVRIHJK. We describe our method of computing the transit path, and the reduction in flux caused by occultation, and compare our lightcurve to an analytic solution with a four-parameter limb-darkening parameterization for the case of an edge-on transit of the Sun by Earth. This capability has been added to all ports and variations, including the Python port, ChromaStarPy, and the version that interpolates among the fully line-blanketed ATLAS9 surface intensity distributions, ChromaStarAtlas. All codes may be accessed at www.ap.smu.ca/OpenStars and at GitHub (github.com/sevenian3).
