Scientific paper

The study derives improved photometric orbits and apsidal motion
parameters from recent observations of YY Sgr (B5 + B6). The new orbits
are consistent with previous work on this system, but have much higher
accuracy. Of the well-known eclipsing binaries, V760 Sco appears to be
the most similar in stellar physical properties.
