Abstract We propose to perform a 250 ks INTEGRAL ToO observation of a transient millisecond X-ray pulsar in outburst. The target can be either one of the ten known transient accreting millisecond X-ray pulsars in the case of a new outburst or a newly observed object of this class. As these transient sources have broad astronomical interest, an outburst will trigger ToO criteria with other X-ray observatories. These observations can be coordinated in order to study the broad band spectrum in detail from hard to soft X-ray energies as well as the timing properties or eclipsing features of the source during its outburst. This will allow us to disentangle the contribution of soft black body, reflection (if any) and hard Comptonized spectral components, as well as the detection of type-I X-ray bursts, or for the first time also burst oscillation at high energy (if present). In particular we will be able to study the energy spectrum of these sources, which is usually observed to be quite hard even in outburst, in a broad band energy range and with unprecedented high sensitivity above 20 keV. The INTEGRAL observation will also allow a timing analysis to study the pulse profile, time lags, total and pulsed spectrum in an interesting energy range also for in future planed missions.

Mission Description The INTEGRAL (International Gamma-Ray Astrophysics Laboratory) mission, launched by the European Space Agency (ESA) on October 17, 2002, was designed to study high-energy phenomena in the universe. INTEGRAL was operating until february 2025 and it was equipped with three high-energy instruments: the Imager on Board the INTEGRAL Satellite (IBIS), the Spectrometer on INTEGRAL (SPI), and the JEM-X (Joint European Monitor for X-rays). Its Optical Monitoring Camera (OMC) provided optical V-band magnitude measurements, complementing the high-energy observations.
