Monthly Notices of the Royal Astronomical Society, https://doi.org/10.1093/mnras/staf863

Eclipsing binaries are perfect laboratories to measure precise, accurate and model-independent stellar radii and stellar masses, so long as both components are spectroscopically resolved. Resolving both components is difficult in high-contrast binari... Read More about EBLM XV – Revised dynamical masses for the circumbinary planet host Kepler-16 AB, using the SOPHIE spectrograph.
