Lessons from the High-resolution Spectroscopy of AW UMa and ϵ CrA: Is the Lucy Model Valid?
A re-examination of high-resolution spectral monitoring of the W UMa–type binaries AW UMa and ϵ CrA casts doubt on the widely utilized L. B. Lucy model of contact binaries. The detection of the very faint profile of the secondary component in AW UMa leads to a new spectroscopic determination of the...
