About the target
EA-β Persei-type (Algol) eclipsing systems. Binaries with spherical or slightly ellipsoidal components. It is possible to specify, for their light curves, the moments of the beginning and end of the eclipses. Between eclipses the light remains almost constant or varies insignificantly because of reflection effects, slight ellipsoidality of the components, or physical variations. Secondary minima may be absent. An extremely wide range of periods is observed, from 0.2 to ≥10000 days. Light amplitudes are also quite different and may reach several magnitudes.
HW- HW Vir-type systems consisting of a hot subdwarf and a red or brown dwarf companion. These show a significant reflection effect.
