X-ray burst (XRB) light curves, powered by surface nuclear burning on an accreting neutron star, are a direct observable that when compared to models provide an independent way to constraint the neutron star mass-radius relation. The ²²Mg(α,p)²⁵Al reaction, identified as one of the most important for understanding XRB light curves, has been measured using a radioactive beam and active-target detector at the NSCL. Learn more
