Searching for periodicities in the MACHO light curve of LMC X-2
Searching for periodicities in the MACHO light curve of LMC X-2
Using the exceptional long-term monitoring capabilities of the MACHO project, we present here the optical history of LMC X-2 for a continuous 6-yr period. These data were used to investigate the previously claimed periodicities for this source of 8.15 h and 12.54 d: we find upper limits of 0.10 mag …
