Data from the SDSS survey are used to study two galaxies with X-structures (UGC 501 and UGC 12253) visible from the edge. Both objects are spiral galaxies of late morphological types with extended stellar disks. The X-structures in the galaxies have different sizes and shapes. The possibility that the different observational parameters of the X-structures in UGC 501 and UGC 12253 are related to different characteristics of their underlying galaxies is discussed (primarily in the relative contribution of the dark halo).

两个具有 X 结构的星系的光度学研究

来自SDSS调查的数据用于研究从边缘可见的两个具有X结构(UGC 501和UGC 12253)的星系。这两个天体都是具有扩展星盘的晚期形态类型的螺旋星系。星系中的 X 结构具有不同的大小和形状。讨论了 UGC 501 和 UGC 12253 中 X 结构的不同观测参数与其下伏星系的不同特征相关的可能性(主要是暗晕的相对贡献)。
