Light curve solutions and out-of-eclipse variability of KIC 10031409, KIC 11228612, KIC 11403216 and KIC 11913071
We carried out light curve solutions of four detached binaries observed by Kepler. As a result, their orbital inclinations, temperatures and relative stellar radii were determined. KIC 10031409 and KIC 11228612 reveal partial eclipses while the components of KIC 11403216 and KIC 11913071 un...

| Summary: | We carried out light curve solutions of four detached binaries observed by
Kepler. As a result, their orbital inclinations, temperatures and relative
stellar radii were determined. KIC 10031409 and KIC 11228612 reveal partial
eclipses while the components of KIC 11403216 and KIC 11913071 undergo total
eclipses. The secondary component of KIC 11403216 is probably a very late M
dwarf or brown dwarf. The out-of-eclipse brightness of KIC 10031409, KIC
11228612 and KIC 11913071 vary with the orbital period and might be explained
by spots on synchronously-rotating star(s). The out-of-eclipse variability of
KIC 11403216 is with a period that is a third of its orbital period and may
be due to spot on asynchronous rotating component. The resonance 1:3 needs
future study of KIC 11403216. |
