Superexpansion as a possible probe of accretion in 4U 1820-30
J. J. M. in 't Zand, J. Homan, L. Keek +1
The ultracompact X-ray binary 4U 1820-30 is well known for its ~170-d superorbital modulation in X-ray flux and spectrum, and the exclusiveness of bursting behavior to the low hard…
LOFT: the Large Observatory For X-ray Timing
M. Feroci, J. W. den Herder, E. Bozzo +245
The LOFT mission concept is one of four candidates selected by ESA for the M3 launch opportunity as Medium Size missions of the Cosmic Vision programme. The launch window is curren…
A superburst candidate in EXO 1745--248 as a challenge to thermonuclear ignition models
D. Altamirano, L. Keek, A. Cumming +6
We report on Chandra, RXTE, Swift/BAT and MAXI observations of a ~1 day X-ray flare and subsequent outburst of a transient X-ray source observed in October-November 2011 in the glo…
Photospheric radius expansion in superburst precursors from neutron stars
L. Keek
Thermonuclear runaway burning of carbon is in rare cases observed from accreting neutron stars as day-long X-ray flares called superbursts. In the few cases where the onset is obse…
Superburst Models for Neutron Stars with Hydrogen and Helium-Rich Atmospheres
L. Keek, A. Heger, J. J. M. in 't Zand
Superbursts are rare day-long Type I X-ray bursts due to carbon flashes on accreting neutron stars in low-mass X-ray binaries. They heat the neutron star envelope such that the bur…
