| Research Abstract |
The galaxy so-called E+A galaxy(or post-starburst galaxy) is a population which was in starburst several ten Mega years ago and then suddenly stopped the starformation. We aimed to understand their physical origin throughobservation, and obtained new insights. In cluster environment, wheremany galaxies are clustered, it is implied that the stop of the starformation is caused by a gas stripping in low mass galaxies. Meanwhile, we made a quantitative discussion of galaxy pair one of which has a starforming region and a post-starburst region in it in field environment.
