Optical observations of IGR J00291+5934 in the post outburst phase
Abstract
We present optical observations of the newly discovered accretion powered millisecond pulsar IGR J00291+5934, undertaken in the weeks following its outburst on 2nd December 2004. The decay to quiescence is seen to be highly variable with no indication of a modulation on the ∼2.46 hr orbital period apparent in the data, consistent with a system at low inclination. We also have a single Keck LRIS spectrum of the companion to IGR J00291+5934 taken 10 days after outburst. Strong hydrogen and helium emission lines are observed confirming the identity of the counterpart.
