Published Papers
Miscellaneous :

Landi et al. 2008 ATel 1538:
  • 2 USNO B1.0 sources, 3 2MASS in Swift error
  • X-ray data well described by an unabsorbed flat (Γ~0.17) power law
  • F2-10 keV5.8 x 10-11 erg/cm2/s
Tomsick et al. 2009:
  • Chandra observation =>position consistent with Swift
  • Spectra well fitted with absorbed power law: NH=18x1022 cm-2 Γ=1.9
  • High and variable NH (compared to Swift), could suggest HMXB
  • IR counterpart has J=13.58, H=12.69, Ks=12.84. Not in the other catalogues

Dai et al. 2011 (MNRAS) :
  • 19.99d periodicity from Swift/BAT lc
  • XRT analysis of pointings occurring on two different orbital phases
  • Detection in only one of the phases
  • Absorbed (17 x 1022 cm-2) power law (Γ=2.3)
  • Large variations suspected
  • Be-HMXB favoured
