Soft X-Ray Transients in quiescence

Soft Xray transient (SXT) behaviour is exhibited by both neutronstarand blackhole systems. While their outburst behaviour is verysimilar, the presence of an event horizon is believed to causesignificant differences in their quiescent properties. However,current results are equivocal and it is essential to observe moresystems with greater sensitivity. We therefore propose to observe 6 SXTs in quiescence, in order to quantify the luminosity difference between neutronstar/blackhole systems, so as to test the ADAF/ADIOS paradigm for accretion in quiescence. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
