| Miscellaneous :

Bulgarelli et al. 2009 ATel 2017:
- Possible counterpart to AGL J1734-3310
|
|
Vercellone et al. 2009ATel 2019:
- Swift observations => 2 sources within INTEGRAL error box
- First is the counterpart
- Flux increase by a factor of 10 in 7 hours
- Spectrum well fitted by an absorbed bbody, kT=1.4 keV, and
NH=5 x 1022 cm-2
|
|
Tomsick 2009ATel 2022:
- Chandra observation => 2 sources, slightly offset from Swift positions
- Source 1 is the counterpart in agreement with Swift.
- 2MASS J17352760-3255544 has
J=12.51, H=10.99, and Ks=10.27
- Absorbed power law, NH=7.5 x 1022 cm-2,
Γ=0.54
- HMXB suggested
|
|
D'ai et al. 2010ATel 2596:
- Strong modulation
at 8.452d in the 15-50 keV BAT light curve=> orbital period of the system.
- Folded light curve is structured with an inferred eclipse at 52726.25 ± n P_orb
- Spectral analysis of the total spectrum is also provided
|
|
Dai et al. 2011 (MNRAS)
: - 8.448d periodicity from Swift/BAT lc
- XRT analysis of pointings occurring on two different orbital phases
- Two possible counterparts in the IBIS error box : non-detection of
the favored one at the expected phase of lowest activity => further associate
it to the IBIS source
- Spectrum : absorbed (NH = 10.6 x 1022 cm-2) power law
(Γ=2.6)
- Cut off improves the fit and slightly modify the parameters but cut off
poorly constrained (>18 keV).

Sguera et al. 2011 (MNRAS)
: - Long term INTEGRAL monitoring of IGR J17354-3255 + results from Swift observations
- Weak and persistent source + occasional X-ray flares
- Swift => (maximum flux)/(non-detection) > 300.
- Confirm the 8.4 day period
- Supergiant X-ray binary, although ratio of flux variations => intermediate SFXT
- Associated with AGL J1734-3310 ?

|
Bozzo et al. 2012 (A&A)
: - XMM-Newton observation
- Two X-ray candidates, only one favoured
- Spectral analysis
- Source is an SFXT
|
|
Ducci et al. 2013 (A&A)
: - Swift monitoring spanning 1.2 orbital periods
- Unambiguous association with src 1 (see Tomsick et al. 2009)
- X-ray light curve => moderated orbital modulation and dip
- Eclipse or onset of gated mechanism most likely explanation for the dip
|
|
Coleiro et al. (2013) :
- NTT/Sofi NIR Spectroscopy
- He I in absorption
- O8.5Iab(f) or O9Iab companion
