【摘要】 恒星年龄,是恒星物理学中一个十分重要的问题,这个问题是否能够得到很好的解决,涉及到天文学中很多其他的重要问题。小到为了确定外星行星的年龄,大到宇宙的年龄,都与恒星的年龄直接有关。本文将简要地介绍目前在天文学中究竟有哪些方法可以用来推断和估计恒星的年龄,以及这些方法都还存在着哪些问题影响恒星年龄估值的准确性。更多还原

【Abstract】 It is a very important problem to determine the ages of stars in the stellar physics.Whether it can be well resolved or not is related to many other important issues in astronomy.The ages of stars are directly related to those from estimating ages of extrasolar planets to the age of the universe.In this paper,it is briefly described which ways in astronomy can be currently used to infer and estimate the ages of stars and what difficulties there are still to be introduced by the uncertainties in the evaluation of stellar ages with these methods.更多还原
