Age-metallicity relation via photometry

Using a widely used stellar-population synthesis model, we study the possibility of using pairs of AB system colours to break the well-known stellar age-metallicity degeneracy...

本研究采用一款广泛使用的恒星群体合成模型（stellar-population synthesis model），探究利用AB系统颜色对（AB system colours）破解学界熟知的恒星年龄-金属丰度简并（stellar age-metallicity degeneracy）的可能性……
