Exploring jet-launching conditions for supergiant fast X-ray transients
Context. In the magneto-centrifugal mechanism for jet formation, accreting neutron stars are assumed to produce relativistic jets only if their surface magnetic field is weak enough (B ∼ 108 G). However, the most common manifestation of neutron stars are pulsars, whose magnetic field distribution peaks at B ∼ 10 G. If the neutron star magnetic field has at least this strength at birth, it must ...
متن کاملMonitoring Supergiant Fast X–ray Transients with Swift. Results from the first year
The advent of Swift has allowed, for the first time, the possibility to give Supergiant Fast X–ray Transients (SFXTs), the new class of High Mass X–ray Binaries discovered by INTEGRAL, non serendipitous attention throughout most phases of their life. In this paper we present our results based on the first year of intense Swift monitoring of four SFXTs, IGR J16479−4514, XTE J1739−302, IGR J17544...
متن کاملMonitoring 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 کاملAre There Magnetars in High Mass X-ray Binaries? the Case of Supergiant Fast X-ray Transients
In this paper we survey the theory of wind accretion in high mass X-ray binaries hosting a magnetic neutron star and a supergiant companion. We concentrate on the different types of interaction between the inflowing wind matter and the neutron star magnetosphere that are relevant when accretion of matter onto the neutron star surface is largely inhibited; these include the inhibition through th...
متن کاملSupergiant Fast X-ray Transients: a New Class of High Mass X-ray Binaries Unveiled by Integral
INTEGRAL monitoring of the Galactic Plane is revealing a growing number of recurrent X-ray transients, characterised by short outbursts with very fast rise times (∼ tens of minutes) and typical durations of a few hours. Here we show that several of these transients are associated with OB supergiants and hence define a new class of massive X-ray binaries which we call Supergiant Fast X-ray Trans...
