RR Lyn is a detached eclipsing binary with a 9.95 d orbit containing two A-stars: one metallic-lined and one possibly metal-poor. We use the light curve from the TESS satellite and two sets of published radial velocity measurements to determine the properties of the system to high precision. We find masses of 1.939± 0.007 and 1.510± 0.003 M⊙, and radii of 2.564± 0.019 and 1.613± 0.013 R⊙. After adjusting published effective temperatures upwards by 200 K we find a good agreement with theoretical…
