Possible detection of a second planetary nebula in M15 at Hα
Abstract
Summary. With a prefiltered slitless spectrograph operating at H , the center of M 15 appears bright and smaller than a dispersed star image. This observation supports the interpretation of the 10 m infrared source at the center of M 15 as being a planetary nebula. Key words: globular clusters - H cc object - planetary nebulae
