Monitoring Supergiant Fast X-ray Transients with Swift. Rise to the Outburst in Igr J16479−4514
IGR J16479−4514 is a Supergiant Fast X–ray Transient (SFXT), a new class of High Mass X–ray Binaries, whose number is rapidly growing thanks to the INTEGRAL observations of the Galactic plane. It was regularly monitored with Swift/XRT since November 2007, to study the quiescent emission, the outburst properties and their recurrence. A new bright outburst, reaching fluxes above 10 −9 erg cm −2 s...
متن کاملDiscovery of the orbital period in the supergiant fast X - ray transient IGR J 17544 – 2619
The supergiant fast X-ray transient (SFXT) system IGR J17544–2619 has displayed many large outbursts in the past and is considered an archetypal example of SFXTs. A search of the INTEGRAL/ISGRI data archive from MJD 52698–54354 has revealed 11 outbursts and timing analysis of the light curve identifies a period of 4.926±0.001 days which we interpret as the orbital period of the system. We find ...
متن کاملIGR J 16194 − 2810 : a new symbiotic X – ray binary ⋆
We here report on the multiwavelength study which led us to the identification of X–ray source IGR J16194−2810 as a new Symbiotic X–ray Binary (SyXB), that is, a rare type of Low Mass X–ray Binary (LMXB) composed of a M-type giant and a compact object. Using the accurate X–ray position allowed by Swift/XRT data, we pinpointed the optical counterpart, a M2 III star. Besides, the combined use of ...
متن کاملMonitoring Supergiant Fast X-ray Transients with Swift. Iii. Outbursts of the Prototypical Sfxts Igr J17544−2619 and Xte
IGR J17544−2619 and XTE J1739−302 are considered the prototypical sources of the new class of High Mass X–ray Binaries, the Supergiant Fast X–ray Transients (SFXTs). These sources were observed during bright outbursts on 2008 March 31 and 2008 April 8, respectively, thanks to an on-going monitoring campaign we are performing with Swift, started in October 2007. Simultaneous observations with XR...
متن کاملIgr J08408–4503: a New Recurrent Supergiant Fast X-ray Transient
The supergiant fast X-ray transient IGR J08408–4503 was discovered by INTEGRAL on May 15, 2006, during a bright flare. The source shows sporadic recurrent short bright flares, reaching a peak luminosity of 10 erg s within less than one hour. The companion star is HD 74194, an Ob5Ib(f) supergiant star located at 3 kpc in the Vela region. We report the light curves and broad-band spectra (0.1–200...
