XMM-Newton detection of Nova Muscae 1991 in quiescence
The soft X-ray transient GU Mus has been detected by XMM-Newton in the quiescent state. The source is very faint, with a 0.5–10.0 keV unabsorbed flux of ergs cm-2 s-1. The spectra is well fit by an absorbed powerlaw with a photon index of , close to the value seen …
