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: |
|
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.
