Hej,

Her er den abstract jeg har sendt til DFS' møde.

Long X-ray burst monitoring with INTEGRAL
By Jérôme Chenevez

Presentation type: talk
X-ray bursts are thermonuclear explosions on the surface of accreting
neutron stars in low mass X-ray binary systems. In the frame of the
INTEGRAL observational Key Programme over the Galactic Center a good
number of the known X-ray bursters are frequently being monitored. An
international collaboration lead by the JEM-X team at the Danish
National Space Center has proposed to exploit the improved sensitivity
of the INTEGRAL instruments to investigate the observational properties
and physics up to high energies of exceptional burst events lasting
between a few tens of minutes and several hours. Of special interest are
low luminosity bursting sources that exhibit X-ray bursts of very
different durations allowing to study the transition from a
hydrogen-rich bursting regime to a pure helium regime and from helium
burning to carbon burning. I will present results obtained from INTEGRAL
archive data and from our previous proposal for the observation period
2006-2007. The comparison of these observations with the current burst
theories confirms the relation between bursting regimes and the
accretion states of the system.
