  • 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

  • Zeeman effect in sulfur monoxide. A tool to probe magnetic fields in star forming regions
    Context. Magnetic fields play a fundamental role in star formation processes and the best method to evaluate their intensity is to measure the Zeeman effect of atomic and molecular lines. However, a direct measurement of the Zeeman spectral pattern from interstellar molecular species is challenging due to the high sensitivity and high spectral
