Our team has obtained HST WFPC2 images of this prototypical example of a planetary nebula in a globular cluster. K 648 was cataloged as a star by Kustner, but identified spectroscopically as a planetary nebula by Pease, both in the 1920's. General WFPC2 view of M15 and K 648 (located near top left edge) . ... The nucleus is shown to have an unusually high mass of 0.60 Msun, and we argue that it must have undergone mass augmentation in a binary that has undergone mass transfer or a merger. ...
