Fundamental planes of early-type galaxies

We derive the fundamental plane (FP) relation for a sample of 1430 early-type galaxies (ETGs) in the optical (r band) and the near-infrared (K band), by combining SDSS-DR5 and...我们结合斯隆数字巡天第五次数据发布（SDSS-DR5）等数据，为包含1430个早型星系（early-type galaxies，ETGs）的样本推导出其在光学（r波段）与近红外（K波段）下的基本平面（fundamental plane，FP）关系。
