对NGC 185(4)、NGC 205(12)和NGC 221(10)中的行星状星云进行了鉴别。星云是通过分离出它们的STAO III来识别的!λ 5007和H α发射线。这些星云将允许直接确定本星系群中椭圆星系的化学丰度。(auth)
Identifications of planetary nebulae in NGC 185 (4), NGC 205 (12), and NGC 221 (10 are presented. The nebulae were identified by isolating their STAO III! lambda 5007 and H alpha emission lines. These nebulae will allow a direct determination of chemical abundances in elliptical galaxies in the Local Group. (auth)
