Fast photometry of candidates for the optical/IR counterpart of the X-ray pulsar 1E2259 + 586

We present new IR fast photometric observations of possible optical counterparts to the X-ray pulsar 1E2259 + 586. Contrary to previous work, we detected no IR pulsations from any of the candidates. We conclude that this removes any remaining support for the tentative 2300 s orbital period, and inde...

Summary:We present new IR fast photometric observations of possible optical counterparts to the X-ray pulsar 1E2259 + 586. Contrary to previous work, we detected no IR pulsations from any of the candidates. We conclude that this removes any remaining support for the tentative 2300 s orbital period, and indeed the evidence that this is in fact a binary system is now completely circumstantial. The identity of the optical counterpart is once more unknown.
