X-ray follow-up to identify faint X-ray transients
Abstract
We propose to trigger a maximum of 2 XMM follow-up observations on known transient sources discovered with INTEGRAL and RXTE, if they undergo a new outburst. We ask for 30 ks per observation,to get a high-quality X-ray spectrum and search for X-ray pulsations and/or bursts. The identification of the sources we are proposing here is particularly important because the selected targets are suspected to belong to the class of Very Faint X-ray Transients (VFXTs), X-ray binaries with outburst peak luminosities of 1E34-1E36 erg/s, thought to be the faintest known accretors, with still poorly understood mechanism for their subluminous outbursts.
