Swift observed an outburst from the supergiant fast X-ray transient (SFXT) AX J1841.0−0536 on 2010 June 5, and followed it with X-ray Telescope (XRT) for 11 d. The X-ray light curve shows an initial flare followed by a decay and subsequent increase, as often seen in other SFXTs, and a dynamical range of ∼1600. Our observations allow us to analyse the simultaneous broad-band (0.3–100 keV) spectrum of this source, for the first time down to 0.3 keV, which can be fitted well with models usually… Expand

Multiple flaring activity in the supergiant fast X‐ray transient IGR J08408−4503 observed with Swift
The durations of the flares as well as the times of the outbursts suggest that the orbital period is ∼35 d, if the flaring activity is interpreted within the framework of the Sidoli et al. model with theOutbursts triggered by the neutron star passage inside an equatorial wind inclined with respect to the orbital plane.
