X-ray Transients in M31
A bright X-ray transient in M31 was detected in a 5000-sec Chandra ACIS-I observation on 2001 Aug 31.54 UT. The new transient (CXOU J004305.5+411703) is located at R.A. = 00h43m05s.55, Decl = +41o17'03''.3 (equinox 2000.0; based on the aspect solution, with uncertainty of ~1''). The energy spectrum can be fitted with a power-law model with a photon

X-shooter Observations of Main-sequence Stars in the Globular Cluster NGC 2808: First Chemical Tagging of a He-normal and a He-rich Dwarf
We present the first chemical composition study of two unevolved stars in the globular cluster NGC 2808, obtained with the X-shooter spectrograph at VLT. NGC 2808 shows three discrete, well-separated main sequences. The most accepted explanation for this phenomenon is that their stars have different helium contents. We observed one star on the

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 =~ 1.1 x 10-14 ergs cm-2 s-1. The spectra is well fit by an absorbed powerlaw with a photon index of alpha = 1.6 +/- 0.4, close to the value seen when the source was in the low/hard state in Aug

XMM-Newton Observations of V404 Cygni in Quiescence
We present a new 40ks XMM observation of the black hole X-ray nova V404 Cyg in quiescence. Its quiescent spectra can be best fitted by a power-law with slope Gamma 2 as found previously. V404 Cyg was roughly equal in luminosity compared to the previous observation of Chandra with variability of a factor of 4 during the observation. We find no
