The Burst Behavior of the Eclipsing Low-Mass X-Ray Binary MXB 1659-298

We present a detailed study of the correlations between the burst properties and the inferred mass accretion rate for the X-ray transient MXB 1659-298. The bursts that exhibited oscillations were observed when the source was at a relatively high mass accretion rate, similar to what has been seen for other sources. However, owing to the limited number of observations at lower mass accretion rates, no bursts were observed at such accretion rates, and it is still possible that when MXB 1659-298 accretes at such low-mass accretion rates, bursts can occur that might still exhibit burst oscillations. No clear correlations were found between the different burst properties and the accretion rate, in contrast to what has been found for KS 1731-260 and 4U 1728-34, but similar to what has been reported for Aq1 X-1. However, this lack of correlation for MXB 1659-298 and Aq1 X-1 might be due to the limited range of the mass accretion rate observed for those sources compared to KS 1731-260 and 4U 1728-34.
