1996AJ....111..197S VARIABLE STARS IN THE DWARF GALAXY IC 10 A. SAHA Space Telescope Science Institute, 3700 San Martin Drive, Baltimore, Maryland 21218 JOHN G. HOESSEL Washburn Observatory, University of Wisconsin-Madison, 475 N. Charter Street, Madison, Wisconsin 53706 JOHN KRIST Space Telescope Science Institute, 3700 San Martin Drive, Baltimore, Maryland 21218 G. EDWARD DANIELSON Palomar Observatory. California Institute of Technology, 170-25, Pasadena, California 91125 Received 1995 August 30; revised 1995 August 24 ABSTRACT Repeated images of the dwarf galaxy IC 10 obtained over a period of 11 years have been used to find variable stars. Four of these stars appear to be Cepheids, from which a distance modulus has been derived. The foreground reddening to this galaxy is E(g - r) ~ 1.00 mag [E(B - V) ~ 0.94 mag], which has been independently derived from the Cepheids, and from the blue supergiants seen in IC 10. Several of the variable stars appear to be have periods and light curves like the Cepheids, but actually lie among the red supergiants. The exact nature of these objects is not very well established. The bona-fide Cepheids yield a true distance modulus of 24.59+/-0.30 (distance of 830 kpc).
