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
