They are thought to be due to sudden accretion events and are referred to as type II X-ray bursts (Hoffman et al 1978).…”

“…Type I X-ray bursts (hereafter X-ray bursts, except when needed) in low-mass X-ray binaries are thermonuclear runaways in freshly accreted material on the surface of a neutron star (for a review see Lewin et al 1993). The freshly accreted matter is compressed and heated, on a time scale of hours to days, to densities and temperatures adequate for thermonuclear ignition.…”

“…All but one (AC 211 in NGC 7078) have shown type I X-ray bursts 1 , proving they harbour neutron stars. Several of these X-ray bursts exhibited a photospheric radius expansion phase (see, e.g., Lewin et al 1993, and references therein). We here show that the peak luminosity of radius expansion bursts from about two third of the X-ray bursters in globular clusters do indeed reach an empirical critical luminosity, and may be used as approximate standard candles for other sources.…”

“…The average type I X-ray burst peak flux is about 1.7×10 −8 erg cm −2 s −1 (SAS-3; Marshall et al 1979). For a more detailed account of the properties of MXB 1730−335 we refer to Lewin et al (1993), Guerriero et al (1999), and Masetti et al (2000), and references therein. Table B.1.…”

Abstract. We examined the maximum bolometric peak luminosities during type I X-ray bursts from the persistent or transient luminous X-ray sources in globular clusters. We show that for about two thirds of the sources the maximum peak luminosities during photospheric radius expansion X-ray bursts extend to a critical value of 3.79±0.15×10 38 erg s −1 , assuming the total X-ray burst emission is entirely due to black-body radiation and the recorded maximum luminosity is the actual peak luminosity. This empirical critical luminosity is consistent with the Eddington luminosity limit for hydrogen poor material. Since the critical luminosity is more or less always reached during photospheric radius expansion X-ray bursts (except for one source), such bursts may be regarded as empirical standard candles. However, because significant deviations do occur, our standard candle is only accurate to within 15%. We re-evaluated the distances to the twelve globular clusters in which the X-ray bursters reside.

“…Due to the strongly variable X-ray background at 8-50 keV, however, the minimum detectable flux can vary strongly. PRE bursts reach the Eddington limit, which for a 1.4M  neutron star is in the range [1.6-3.8] × 10 38 erg s −1 (depending of the radius and composition of the photosphere; see, e.g., Lewin et al 1993;Kuulkers et al 2003). In order to test whether the flux distribution is consistent with thermonuclear bursts from the Galactic bulge, we adopt a fiducial Eddington luminosity of L Edd =2.5×10 38 erg s −1 , and show in Figure 12 the 10-100 keV fluxes corresponding to L Edd at distances of 8 and 10 kpc (horizontal lines labelled L Edd,8 and L Edd,10 ).…”

The Fermi Gamma-ray Burst Monitor (GBM) is an all-sky gamma-ray monitor well known in the gamma-ray burst (GRB) community. Although GBM excels in detecting the hard, bright extragalactic GRBs, its sensitivity above 8 keV and its all-sky view make it an excellent instrument for the detection of rare, short-lived Galactic transients. In 2010 March, we initiated a systematic search for transients using GBM data. We conclude this phase of the search by presenting a three-year catalog of 1084 X-ray bursts. Using spectral analysis, location, and spatial distributions we classified the 1084 events into 752 thermonuclear X-ray bursts, 267 transient events from accretion flares and X-ray pulses, and 65 untriggered gamma-ray bursts. All thermonuclear bursts have peak blackbody temperatures broadly consistent with photospheric radius expansion (PRE) bursts. We find an average rate of 1.4 PRE bursts per day, integrated over all Galactic bursters within about 10 kpc. These include 33 and 10 bursts from the ultra-compact X-ray binaries 4U0614+09 and 2S0918-549, respectively. We discuss these recurrence times and estimate the total mass ejected by PRE bursts in our Galaxy.
