E+A星系的特征是具有强的巴耳末吸收线,但没有任何(OII)或Hα发射线。强巴耳末吸收线的存在意味着E+A星系在过去的1亿年内经历了一次星爆,整个样本被尘埃消光所掩盖,而15个(z < 0.08)E+ A星系的SFR上限较低,为1.15亿年。
E+A galaxies are characterized as a galaxy with strong Balmer absorption lines but without any (OII) or Hα emission lines. The existence of strong Balmer absorption lines means that E+A galaxies have experienced a starburst within the last 100 Myr −1 ) hidden by dust extinction for the whole sample while 15 (z < 0.08) E+As have lower SFR upper limits of ∼15 Myr −1 .
