Published Papers
Miscellaneous :
Bozzo et al. 2011 ATel 3326:
  • 2 Swift follow up observations
  • Spectrum: absorbed power-law NH=6.5 x1022 cm-2, Γ=1.8
  • 2MASS J19145680+1036387 has J=14.34, H=12.41, K=11.53
Cusumano et al. 2016 (MNRAS):
  • Analysis of long term Swift monitoring
  • BAT ligth curve => modulation at 22.25 d interpreted as the orbital period of the system
  • XRT+BAT spectrum => absorbed (NH=3.9e22 cm-2) power law (Γ=0.9) with high energy cut-off (24 keV)
  • Presence of cyclotron absorption line @ 31.2 keV => Bsurface~3.6 1012 G
