Black hole X-ray binary ? 2MASS J17452768-2919534 Paizis et al. 2015, ATel 7020
Published Papers
Miscellaneous :
Tendulkar et al. (2014)ATel 6574 :
  • NuSTAR observations
  • No evidence for burst or pulsation
  • Energy spectrum <=> absorbed (NH~3.3 e22 cm-2) power law (Γ~1.5 with exp. cut-off (Efold> 100 keV) and broad Iron line
  • Power spectrum <=> 1 zero-centred Lorentzian and power law component; fract RMS ~ 25%
  • Properties consistent with a black hole X-ray binary in the hard state
Paizis et al. (2015)ATel 7020 :
  • Chandra Observation => refinement of X-ray position
  • Identification of 2MASS J17452768-2919534 as probable IR counterpart
  • J=16.227, H=13.038, Ks=11.365
Paizis et al. 2015 (ApJ) :
  • Chandra, Swift and INTEGRAL observations
  • X-ray broad band spectrum => absorbed power law, NH =10-12 1022cm-2 Γ=1.6-1.8, no cut off up to ~ 100 keV
  • No evidence for broad iron line
  • GROND observations of optical counterpart => J=16.07, H=13.10, Ks=11.37
  • Characteristics typical of a low mass X-ray binary, no indication on the nature of the compact object
