Abstract

Interaction between galaxies is of critical importance to the growth and evolution of galaxies. Due to the lack of studies on interactions between low-mass galaxies, it is still uncertain that how low-mass galaxies evolve during an interacting procedure. This investigation will explore how the internal star-formation activities of low-mass disk galaxies are influenced by the outer environment. The interaction-induced enhancement of star formation rate in diverse galaxy systems will be examined. This work presented here is the first attempt to systematically study the evolution of low-mass disk galaxies, it is also a pioneer of a statistical study on low-mass interacting galaxy systems. This investigation is based on data from the fourth-generation Sloan Digital Sky Survey (SDSS- IV) / Mapping Nearby Galaxies at Apache Point Observatory (MaNGA).
