CV/IP ~190 pc 2MASS and USNO B1.0 Landi et al. 2010
Published Papers
Miscellaneous :
Landi et al. 2010 :
  • Swift observations + multiwavelengths catalog browsing
  • USNO B1.0 counterpart R=14.9-16.45
  • 2MASS counterpart J=15.43, H=15.18 K=15.10
  • Spectral analysis => NH=0.3222 cm-2, &Gamma=1.26
  • Source is not associated with the possible Rosat source in IBIS error
Masetti et al. 2010 (A&A) :
  • Optical spectroscopy of the counterpart
  • R=15.4, Av ~ 0
  • Balmer emission lines up to Hδ at z=0
  • EW ratio of He II/Hβ and He II EW => magnetic CV, IP (although need to be confirmed by spin and orbit period
  • d ~ 190 pc
Bernardini et al. 2013 (MNRAS):
  • XMM-Newton & Swift broad band spectral and timing analysis
  • Highly variable X-ray source: 7.6 h variability and on time scales ~1900s
  • X-ray spectrum well fitted by multi-temperature plasma, with unconstrained high temperature
  • Interstellar and local absorption + partial absorber with covering factor 53%
  • MWD=0.89 Msun
