Published Papers
Miscellaneous :
Kniazev et al. 2008 ATel 1488:
  • SAAO 1.9m telescope
  • 4000-7000A optical spectrum shows bright Balmer emission lines with zero redshift=> Galactic object.
  • Spectrum has an overall blue shape
  • => Typical of CV.
Sazonov et al. 2008 :
  • X-ray absorption measured with Chandra< total Galactic absorption in this direction.
  • Discovery of a period of 1450s
  • Optical and NIR counterparts in USNO B1 and 2MASS catalogues with B = 17.65, R = 16.05, I = 16.83, J = 15.68, H = 15.29, and K = 14.52
  • A magnetic CV (IP) is favoured
Revnivtsev et al. 2009 :
  • Optical spectroscopic analysis =>Galactic Cataclysmic Variable, with strong Balmer emission lines at z=0, and a continuum consistent with other CVs
  • Presence of a nebular emission not too far from the source but no clear association of this nebular feature and the IGR source.
  • Optical light curve => no evidence for periodic variations
Masetti et al. 2009:
  • Optical spectroscopy confirms CV, R=16.6, AV~0
  • d~330pc
Bernardini et al. 2012 (A&A):
  • Multi-wavelengths observations (XMM, INTEGRAL)
  • Pulse and orbital periods = 1480.8s and 8 hr
  • Pulse also seen in the UVs
  • Broad band spectral analysis
  • Absorption edge at 0.76 keV from OVII detected
  • Source is a pure disc accretor
  • MWD~0.95 Msun at d~1200 pc
