Abstract:
We present the results of our analysis of the JEM-X/INTEGRAL data
obtained from January 2003 to January 2015 aimed at searching for type
I X-ray bursts from known and new bursters. Such bursts are caused by
thermonuclear explosions on the surface of a neutron star. We have
searched for bursts in the records of the count rate of the JEM-X
detectors in the 3-20keV energy band. We have separately
reconstructed and analyzed the light curves of 104 X-ray bursters
known to date based on the JEM-X data. A similar search for bursts was
previously carried out in the 15-25keV data from the IBIS/ISGRI
telescope onboard the INTEGRAL observatory obtained in 2003-2009. We
have continued to analyze the data from this telescope up until the
observations in January 2015. The joint catalog of bursts detected by
the two instruments includes 2201 events; their basic parameters are
given. The large size of the sample of bursts makes it one of the most
representative of the existing one and allows various statistical
studies of bursts to be performed. In particular, we have constructed
the dependence of the mean rate of type I bursts from bursters on the
luminosity (accretion rate), revealed an appreciable burst rate from
sources with a near-Eddington luminosity, and investigated the
population of multiple bursts with a recurrence time much shorter than
the time it takes for a critical mass of matter required for the
initiation of an explosion to be accumulated on the neutron star
surface. Almost all of the detected bursts are associated with already
known bursters,we have found only one previously unknown burster,
IGRJ17380-3749, in the archival data, and one more known, but poorly
studied source, AX J1754.2-2754, has been identified as a burster.
Several similar sources have previously been identified as bursters
directly during the INTEGRAL observations.
Description:
Already 103 X-ray bursters1 are known to date.
Table 2 gives the list of X-ray bursters from which type I bursts were
detected during our investigation.
