Optical CCD photometry of the microquasar LS 5039
We report optical CCD observations of the microquasar LS 5039. Its photometric behaviour is studied over different orbital periods with a time separation of three years. We do not detect evidences of an ellipsoidal modulation above the $\pm0.01$ mag level, thus confirming the previous results report...

Summary: | We report optical CCD observations of the microquasar LS 5039. Its photometric behaviour is studied over different orbital periods with a time separation of three years. We do not detect evidences of an ellipsoidal modulation above the $\pm0.01$ mag level, thus confirming the previous results reported by Clark et al. ([CITE]). The light curve of LS 5039 has also been explored with a time resolution of 30 s but the source also appears to be stable on such shorter time scales. Possible scenarios consistent with the non-detection of optical variability are considered. |
