The Be/neutron star binary system, SXP 5.05, has been detected during the S-CUBED regular surveying of the SMC over the last month. The most recent detection was on 2 July 2024 when it exhibited an X-ray luminosity of approximately 4 x 10^37 erg/s (~1 count/sec in the XRT telescope).
This source is a rare Be/X-ray binary system that exhibits X-ray and optical eclipses/dips every 17d (Coe et al, 2015). It has not been detected since its original discovery by INTEGRAL in October 2013. Follow up observations at all wavelengths are encouraged.
S-CUBED is a weekly shallow X-ray survey of the SMC carried out with NASAâs Neil Gehrels Swift Observatory. It has been running almost continuously since 2016 (Kennea et al, 2018) providing long term X-ray light curves of many hundreds of sources located either in, or in the direction of the SMC.
