The solar-type stars show rich variety of magnetic activities such as surface inhomogeneities due to presence of dark spots, short and long-term variations in spot-cycles and flares. Using Swift observations, we present an in-depth study of two superflares (F1 and F2) detected on active binary system CC Eridani. The peak X-ray luminosity in 0.3-50.0 keV reached up to 3×10^32 erg/s and 5×10^31 erg/s, which is ∼3500 and ∼600 times more than the quiescent value and larger than any other previously observed flares on CC Eri. Spectral analysis indicates a presence of three temperature corona with first two plasma temperatures remain constant during the flares at ∼3 MK and ∼10 MK. The flare-temperature peaked at 342 MK and 119 MK for F1 and F2, which is ∼4 and ∼2 times more than the minimum value. The abundances peaked at 2.0 and 1.2 solar abundances, which is larger than a factor 11 and 7 than quiescent values. Using hydrodynamic modeling we derive loop-lengths for both flares to be 1.25±0.13×10^10 cm and 1.26±0.20×10^10 cm, respectively. Significant amount of heating is detected during the decay of both the flares. We model the K-alpha emission feature as fluorescence from the hot flare source irradiating the photospheric iron, and estimate the location of the flare at an astrocentic angle of ∼88.2◦. Using the Kepler observations we have analysed an F-type ultra-fast rotator KIC 6791060. We have developed an automated flare search algorithm to detect the flare and to automatically identify the flare start and end time. During the observations, a total of 38 optical flares are detected. Energies of these flares have been found to vary within a range of 1031−34 erg. Preliminary results of surface temperature modeling indicate an existence of two active longitude region on the stellar surface.
