The effect of accretion on the measurement of neutron star mass and radius in the low-mass X-ray binary 4U 1608-52

Suleimanov, Valery F.; Poutanen, Juri; Nättilä, Joonas +4 more

Spectral measurements of thermonuclear (type I) X-ray bursts from low-mass X-ray binaries have been used to measure neutron star (NS) masses and radii. A number of systematic issues affect such measurements and have raised concerns as to the robustness of the methods. We present analysis of the X-ray emission from bursts observed from 4U 1608-52 a…
