Anyone could tell us more?

    We clearly see some nice transits, one of them made a dim about 50% of the total lightness of star, other transits are also very certain. Do we deal with a dwarf star here? Did anyone studied this planetary system? Would be nice to know.

    Yes, this star (EPIC 204449274) is very interesting. There is a short discussion about it here http://talk.planethunters.org/#/boards/BPH0000005/discussions/DPH0000sco together with some similar stars. The analysis of @ajamyajax does indeed suggest that this is a young red dwarf star in the Upper Sco cluster. It is included as a target for study in the following proposals:

    GO2020 Lodieu Finding transiting exoplanets in Upper Scorpius with Kepler K2

    GO2047 Brown Rotational Properties And Evolution Of Young Stars In Upper Sco: K2-field02

    GO2052 Covey K2 Monitoring of Confirmed Members of Upper Sco + Rho Oph

    The star might be a T-Tauri variable or an eclipsing binary or possibly both.
