C32: A Young Star Cluster in IC 1613
journal contribution
posted on 2023-05-16, 19:29 authored by Wyder, TK, Hodge, PW, Andrew ColeAndrew ColeThe Local Group irregular galaxy IC 1613 has remained an enigma for many years because of its apparent lack of star clusters. We report the successful search for clusters among several of the candidate objects identified many years ago on photographic plates. We have used a single Hubble Space Telescope WFPC2 pointing and a series of images obtained with the WIYN telescope under exceptional seeing conditions, examining a total of 23 of the previously published candidates. All but six of these objects were found to be either asterisms or background galaxies. Five of the six remaining candidates possibly are small, sparse clusters, and the sixth, C32, is an obvious cluster. It is a compact, young object, with an age of less than 10 million years and a total absolute magnitude of M v = -5.78 ± 0.16 within a radius of 13 pc.
