Published Papers
Miscellaneous :
Rodriguez et al. 2009:
  • Swift XRT position consistent with that of 1RXH 173523.7-354013 (position mismatch between SIMBAD and the Rosat Catalogue)
  • 2 USNO-B1.0 objects within XRT error box, the closest to the 2MASS source is considered
  • No UVOT counterpart with UVW1>20.3 and UVM2>20.2
  • J=10.23, H=9.03, Ks=8.63, I=10.9, V=11.9
  • Spectral analysis => absorbed power law Γ=2.1-2.2, NH=0.7 x1022 cm-2 compatible with Galactic value.
  • Variation of fluxes by a factor of 2 seen between different pointings
  • Galactic source, possible HMXB
Degenaar et al. 2010:
  • multi-instrumental observations
  • Detection of X-ray burst=>NS-LMXB
  • Refute the formerly proposed IR counterpart
  • Spectral analysis of the source during and outside of the burst
  • Source is a faint persistent LMXB
  • Burst belongs to the untypical class of intermediately long bursts
