SB profiles of 9 late-type disk galaxies

We use HST ACS and NICMOS imaging to study the inner B-I and I-H colors of nine late-type spiral galaxies, which we interpret on the basis of different star formation histories....我们利用哈勃太空望远镜（Hubble Space Telescope, HST）的先进巡天照相机（Advanced Camera for Surveys, ACS）与近红外相机多目标光谱仪（Near Infrared Camera and Multi-Object Spectrometer, NICMOS）的成像数据，对9个晚型螺旋星系的内部B波段-I波段以及I波段-H波段颜色特征展开研究，并基于不同的恒星形成历史对该颜色特征进行解读。
