1988A&A...195L...1N More isotropic oblate rotators in elliptical galaxies J.-L. Nieto, M. Capaccioli, and E. V. Held Observatoire Midi-Pyrenees, 14, Avenue Edouard Belin, F-31400 Toulouse, France Osservatorio Astronomico, Vicolo Osservatorio 5, I-35100 Padova Italy Received November 17, 1987; accepted January 26, 1988 Summary We have extracted from the literature a list of 24 elliptical galaxies showing evidence for having (inner) disks. Reconsidering the (V/{sigma}, {epsilon}) test, we conclude that kinematical and photometric data (available for 13 galaxies) are consistent with such disk-galaxies being isotropic nearly oblate rotators. We argue that at least about 30 to 50% of genuine E's must have a disk, generally faint, at the low end of the sequence of the disk-to- total luminosity ratio, and are isotropic oblate rotators. Only a favorable orientation reveals the disk in a few of them. Key words: Galaxies: internal motions - Galaxies: classification - Galaxies: structure - Elliptical Galaxies: disks
