Published Papers
Miscellaneous :
Landi et al. 2008 ATel 1538:
  • USNO B1.0 counterpart, also in 2MASS
  • R=16.8-17.8
  • X-ray data well described by an unabsorbed Γ~0.24 power law
  • F2-10 keV1.2 x 10-11 erg/cm2/s
Masetti et al. 2008 ATel 1620 :
  • Optical source shows a red continuum, with possibe absorption by Galactic dust on the line of sight
  • Single narrow emission line, consistent with Hα (EW~17 Angstrom).
  • Optical characteristics =>Galactic X-ray source, likely LMXB
Masetti et al. 2009:
  • d~9.1 kpC
  • Av~3.1
Tomsick et al. 2009:
  • Chandra observation
  • Spectrum = absorbed powerlaw, NH=0.1 x 1022 cm-2, Γ=-0.30
  • Source is more probably an HMXB than a LMXB
