摘要

为了弄清盘状星系外部气体吸积的来源，我们利用特殊天体物理天文台6米望远镜的扫描法布里-珀罗干涉仪研究了四个相互作用星系在Hα发射线上的邻近区域。我们发现透视吸积流被视为星系之间的电离气体发射细丝。我们讨论了这些流的整体运动学和起源。

S0 Galaxies: Outer Gas Accretion through Tidal Interaction and Minor Merging

To clarify the sources of outer gas accretion onto disk galaxies, we study the vicinity of four interacting galaxy systems in the Hα emission line by using the scanning Fabry–Perot interferometer of the 6m telescope of the Special Astrophysical Observatory RAS. We find perspective accretion flows seen as ionized-gas emission filaments between the galaxies. We discuss the whole kinematics and origin of these flows.
