Evolution models of elliptical galaxies. III.

In this study we present a simple model of elliptical galaxies aimed at interpreting the gradients in colours and narrow band indices observed across these systems. Salient...本研究提出了一款针对椭圆星系（elliptical galaxies）的简易模型，旨在阐释此类星系系统中观测到的颜色与窄带指数梯度特征。Salient……
