解开白矮星的光度函数
Untangling the White Dwarf Luminosity Functions
摘要:
白矮星光度函数的反演提供了一种独立于任何宇宙学模型的独立方法来证明银河系过去的恒星形成历史。在Rowell & Hambly(2011)中,有效体积方法使用给定bin中所有对象的平均属性,因此在分析的早期阶段丢失了大量信息,在这项工作中,我探索了使用广义施密特密度估计(1/Vmax)以概率方式分配对象的可能性。
英文摘要:
The inversion of the white dwarf luminosity function provides an independent way to prove the past star formation history of the Milky Way independent of any cosmological models. In Rowell & Hambly (2011), the effective volume method uses the average properties of all the objects in a given bin, so a significant amount of information is lost in the early stage of the analysis, in this work, I explore the possibility of assigning objects individually in a probabilistic way using the generalised Schmidt density estimator (1/Vmax).
