The identification of thousands of carbon stars in Local Group galaxies, by my collaborators and I, offers a unique opportunity to employ these stars as probes to investigate several aspects of the structure and star formation history of these systems. This is the case because carbon stars are easy to distinguish among red giant stars and because they have a well defined luminosity.

我和我的合作者在本星系群中发现了数千颗碳星，这为利用这些恒星作为探测器来研究这些系统的结构和恒星形成历史的几个方面提供了一个独特的机会。这是因为碳星很容易从红巨星中区分出来，而且它们的光度也很明确。
