The very faint X-ray transient Swift J174610-290018 at the Galactic center

Giovanni Stel, Gabriele Ponti, Nathalie Degenaar +17

Very Faint X-ray Transients (VFXTs) are a class of X-ray binary systems that exhibit occasional outbursts with peak X-ray luminosities (L_X< 1e36 erg s^-1) much lower than typical…

The Galactic center X-ray transients AX J1745.6-2901 and GRS 1741-2853

N. Degenaar, R. Wijnands, M. T. Reynolds +3

AX J1745.6-2901 and GRS 1741-2853 are two transient neutron star low-mass X-ray binaries that are located within ~10' from the Galactic center. Multi-year monitoring observations w…

The X-ray flaring properties of Sgr A* during six years of monitoring with Swift

N. Degenaar, J. M. Miller, J. Kennea +2

Starting in 2006, Swift has been targeting a region of ~21'X21' around Sagittarius A* (Sgr A*) with the onboard X-ray telescope. The short, quasi-daily observations offer an unique…

Monitoring Chandra observations of the quasi-persistent neutron-star X-ray transient MXB 1659-29 in quiescence: the cooling curve of the heated neutron-star crust

Rudy Wijnands, Jeroen Homan, Jon M. Miller +1

We have observed the quasi-persistent neutron-star X-ray transient and eclipsing binary MXB 1659-29 in quiescence on three occasions with Chandra. The purpose of our observations w…

A Chandra observation of the long-duration X-ray transient KS 1731-260 in quiescence: too cold a neutron star?

Rudy Wijnands, Jon M. Miller, Craig Markwardt +2

After more than a decade of actively accreting at about a tenth of the Eddington critical mass accretion rate, the neutron-star X-ray transient KS 1731-260 returned to quiescence i…
