Structure and dynamics of 8 low SB disc galaxies

We present the radial profiles of the H{alpha}, Mg and Fe line-strength indices for a sample of eight spiral galaxies with a low-surface-brightness stellar disc and a bulge. The...本研究给出了一个包含8个拥有低表面亮度恒星盘与核球的旋涡星系样本的Hα（H-alpha）、镁（Mg）、铁（Fe）线指数的径向轮廓。该...
