MASSCLEAN - MASSive集群演进和分析包-说明、测试和结果

MASSCLEAN - MASSive CLuster Evolution and ANalysis Package - Description, Tests, and Results

Bogdan Popescu, M. M. Hanson

摘要:

MASSCLEAN是一个新的,复杂的和强大的星团图像和测光模拟包。该软件包能够根据用户输入的聚类特征(包括但不限于距离、年龄、质量、半径和消光),在任何传统的光学和近红外波段创建颜色-星等图和标准FITS图像。在非常遥远的,未解决的集群的限制,我们已经检查了综合颜色创建的MASSCLEAN对那些从其他简单的恒星星族(SSP)模型与一致的结果。由于该算法用离散数量的可维持恒星填充星团,因此它可以用作蒙特卡罗方法的一部分,以获得与给定星团质量和年龄一致的特征(例如,综合颜色)的概率范围。我们提出了有史以来第一个质量依赖的综合颜色作为年龄的函数,来自超过100,000 Monte Carlo运行,它可以用来改善目前的年龄测定方法的星团。

英文摘要:

MASSCLEAN is a new, sophisticated and robust stellar cluster image and photometry simulation package. This package is able to create color-magnitude diagrams and standard FITS images in any of the traditional optical and near-infrared bands based on cluster characteristics input by the user, including but not limited to distance, age, mass, radius and extinction. At the limit of very distant, unresolved clusters, we have checked the integrated colors created in MASSCLEAN against those from other simple stellar population (SSP) models with consistent results. Because the algorithm populates the cluster with a discrete number of tenable stars, it can be used as part of a Monte Carlo Method to derive the probabilistic range of characteristics (integrated colors, for example) consistent with a given cluster mass and age. We present the first ever mass dependent integrated colors as a function of age, derived from over 100,000 Monte Carlo runs, which can be used to improve the current age determination methods for stellar clusters.
