Observed photometric peculiarities of six eclipsing binaries with solar-type activity: I

Astrophysics and Space Science Aims and scope Submit manuscript

Abstract

From the observed light curves of six eclipsing binaries with solar-type activity and from the analysis of their period variations some problems in the interpretation of the observations came out:

Are these binaries similar to classical RS CVn stars?

Is the stellar surface spot coverage the unique interpretation of the observed light curves?

Are these systems really linked with W UMa's?

In a further study some models will be tempted to try to solve these problems.
