Constraining neutron-star properties with ensembles of thermonuclear bursts: application to SRGA J144459.2-604207
Duncan K. Galloway, Serena Jones, Luke Waterson +3
Deducing the properties of the host neutron stars from thermonuclear (type-I) X-ray bursts remains a challenge, due to incomplete data, multidimensional parameter space, and dearth…
