TL;DR
This study measures the radio-X-ray luminosity correlation in the neutron star X-ray binary EXO 1745-248, revealing a unique disc-jet coupling index and contributing to understanding jet production in accreting neutron stars.
Contribution
First measurement of the radio-X-ray luminosity correlation in EXO 1745-248, providing new insights into disc-jet coupling in neutron star X-ray binaries.
Findings
The correlation index β=1.68 in EXO 1745-248 differs from other NSXBs.
EXO 1745-248 is among the most radio faint neutron star X-ray binaries.
A type-I X-ray burst was detected, consistent with hydrogen burning.
Abstract
We present the results of VLA, ATCA, and Swift XRT observations of the 2015 outburst of the transient neutron star X-ray binary (NSXB), EXO 1745248, located in the globular cluster Terzan 5. Combining (near-) simultaneous radio and X-ray measurements we measure a correlation between the radio and X-ray luminosities of with , linking the accretion flow (probed by X-ray luminosity) and the compact jet (probed by radio luminosity). While such a relationship has been studied in multiple black hole X-ray binaries (BHXBs), this work marks only the third NSXB with such a measurement. Constraints on this relationship in NSXBs are strongly needed, as comparing this correlation between different classes of XB systems is key in understanding the properties that affect the jet production process in accreting objects. Our best fit disc-jet…
