PyTransit:快速简单的Exoplanet Transit Python建模

PyTransit: Fast and Easy Exoplanet Transit Modelling in Python

Hannu Parviainen

摘要:

我们提出了一个快速和用户友好的系外行星过境光曲线建模包PyTransit,实现了Gimenéz和Mandel & Agol过境模型的优化版本。该软件包提供了一个面向对象的Python接口,可以访问在Fortran中通过OpenMP并行化原生实现的两个模型。二次Mandel-Agol模型的部分OpenCL版本也包含在GPU加速计算中。PyTransit的目的是促进分析由数十万个数据点组成的系外行星凌日的光度时间序列,以及来自分光光度观测的多通带凌日光变曲线,作为研究人员编程工具包的一部分,用于构建复杂的,特定问题的分析。

英文摘要:

We present a fast and user friendly exoplanet transit light curve modelling package PyTransit, implementing optimised versions of the Gimenéz and the Mandel & Agol transit models. The package offers an object-oriented Python interface to access the two models implemented natively in Fortran with OpenMP parallelisation. A partial OpenCL version of the quadratic Mandel-Agol model is also included for GPU-accelerated computations. The aim of PyTransit is to facilitate the analysis of photometric time series of exoplanet transits consisting of hundreds of thousands of datapoints, and of multi-passband transit light curves from spectrophotometric observations, as a part of a researcher's programming toolkit for building complex, problem-specific, analyses.
