MAXI J1957+032 contains a neutron star, Swift observations suggest

Observations conducted with NASA’s Swift space telescope have provided more insights about the nature of a compact component of the transient low-mass X-ray binary named MAXI J1957+032. Results of these observations, available in a paper published April 1 on arXiv.org, suggest that the system hosts a neutron star.
