A bunch of us have been working on the X-ray data from a quite remarkable transient, IGR J17473-2721, which went into a 6-month long outburst beginning in 2008. The source went through some dramatic changes in the burst behaviour, some of which we think we understand, but some of which we don't. In particular at the beginning and the end of the outburst completely different burst behaviour is observed at roughly the same intensity (accretion rate). This effect may be due to the heating of the neutron star core which has taken place during the outburst. Jerome's paper is out now on astro-ph at arXiv.org:1007.5201.
