Discovery of an 18-d Photometric Period in the Optical Counterpart of Swift J0208.4-7428
Abstract
Swift J0208.4-7428 was identified in Integral/IBIS monitoring of the Magellanic Clouds and, by positional coincidence, correlated with a transient X-ray source in archival Swift/XRT data (McBride et al., 2010, MNRAS, 403, 709). The likely optical counterpart is a bright, blue star in the Magellanic Bridge (Demers & Irwin, 1991, A&AS, 91, 171). Weak H-alpha emission was detected by Masetti et al. (2010, A&A, 519, A96).
