IGR J17451-3022

• Analysis of Swift observations
• Spectrum poorly represented by an absorbed power law, and best represented by black body (kT~0.8 keV, N_H to vary between ~5 and ~7 x 10²² cm-2
• High absorption consistent with location near or beyond Galactic centre

• Analysis of further Swift observations
• Spectra broadly consistent with previous analysis
• Search for pulsations unsuccessful with a typical upper limit of 10% in the range 0.01-280 Hz

• Analysis of further Swift observations
• Spectra of first two observations (Sept. 15 and 19 2014)consistent with being soft and thermal
• Spectrum of the Sept. 21 observation has become harder => Power law (Γ~2.2) gives a better fit
• Spectral hardening favours an LMXB (with d> 8kpc)
• In Feb, 2015 outburst continues with parameters consistent with those obtained before sun constrained period.
• No significant variation over 4-5 months during which the source remained in a bright soft state

• Suzaku observation on 2014 Sept. 23/24
• Strong dipping activity in 0.5-10 keV light curves
• Identification of eclipses with recurrence period 22623s identified as orbital period
• Difficulty to estimate true duration of eclipses but constrained to be < 2600s
• => Strongly inclined system > 70 degrees

• Swift observation durin 2015 May =>decline of brightness until marginal detection
• Spectral analysis of the most recent obs. => consistent with kT=0.6 black body
• => Source is returning to quiescence

• INTEGRAL, Swift and XMM observations
• OUtburst lasted 9 months with source remaining soft over the entire period
• Source spectra dominated by thermal (kT~1.2 keV) emission attributed to accretion disk
• Presence of multiple absorption features with potential presence of ionized absorber above the disk
• Partial and rectangular X-ray eclipse (820s) and dips => source orbital period 22620.5 s (~6.28 hr)
