INTEGRAL/Jem-X image of the field available here
Pooley et al. 2004 (Atel 226):
  • Unresolved radio source detected on Jan. 29 2004 with the Ryle (15 GHz)
Pandey et al. 2006:
  • 36 mJy @1.5GHz
Halpern & Tyagi 2005 Atel 682):
  • most likely counterpart is a Be star within an arcminute of the JEM-X position.
  • also present in the USNO and 2MASS catalogues at B=13.3, R=12.1, J=10.49, H=10.19, and K=9.96.
  • optical spectrum presents H-alpha emission line (EW ~ 0.7 nm) and diffuse interstellar absorption bands.
Masetti et al. 2006 :
  • likely Be HMXB
  • at ~1kpc
  • caution expressed on these results
Tomsick et al. 2006:(Atel 959)
  • Refinement of the X-ray position with Chandra
  • Association with the Be star
  • Hard absorbed spectrum NH=6(+/-2) 1022 cm-2, Gamma=1.3 (+/-0.8)
  • Absorbed 0.3-10 keV flux= 2e-12 erg/s/cm2
Tomsick et al. (2008) :
  • Chandra position confirms all proposed associations
  • Absorbed power law, NH=7.2x1022 cm-2, Γ= 0.9, Unabs. 0.3-10 keV flux=3.5 e-12 erg/cm2/s
Reig et al. 2010(A&A):
  • Companion is a B0.5 Ve star, a B1 Ve cannot be completely excluded
  • Distance of 4.5 kpc = lower limit
  • Profile change of the Hα line => changes in the structure of the disc with a complete disappearance of the latter
Simon et al. 2012ATel 4170:
  • Detection of H-alpha emission line and its V/R variability
  • =>reappearance of a decretion disc in the system IGR J06074+2205.
