Discovery of eclipsing nature of LMC X-4

Nature volume 271, pages 38–40 (1978)Cite this article

Abstract

THE Sandaleak–Philip optical candidate for LMC X-4 (ref. 1) has been reported by Chevalier and Ilovaisky2 to be part of a 1.4-d binary system. Six days of data taken from an extended Ariel V observation of the LMC are shown in Fig. 1 and X-ray eclipses 5 h long can be clearly discerned every 1.4 d. The predicted optical phase zero times are, within the uncertainties, in good agreement with the observed mid-eclipse times, thus confirming the identification and making this the first X-ray eclipsing binary system to be found in the LMC.
