Cool Spot and Flare Activities of a RS CVn Binary KIC 7885570
M. Kunt, H. A. Dal
We present here the results on the physical nature a RS CVn binary KIC 7885570 and its chromospheric activity based on the Kepler Mission data. Assuming the primary component tempe…
Spectroscopic and photometric confirmation of chromospheric activity in four stars
Orkun Özdarcan, Hasan Ali Dal
We present analysis of medium resolution optical spectra and long term V band photometry of four cool stars, BD+13 5000, BD+11 3024, TYC 3557-919-1 and TYC 5163-1764-1. Our spectro…
KOI-256's Magnetic Activity under the Influence of the White Dwarf
Ezgi Yoldaş, Hasan Ali Dal
We present the findings about chromospheric activity nature of KOI-256 obtained from the Kepler Mission data. Firstly, it was found that there are some sinusoidal variations out-of…
High Level Magnetic Activity Nature of an Eclipsing Binary KIC 12418816
Hasan Ali Dal, Orkun Ozdarcan
We present comprehensive spectroscopic and photometric analysis of the detached eclipsing binary KIC 12418816, which is composed of two very similar and young main sequence stars o…
KIC 9451096: Magnetic activity, flares and differential rotation
Orkun Özdarcan, Ezgi Yoldaş, Hasan Ali Dal
We present spectroscopic and photometric analysis of KIC\,9451096, where the latter is based on very high precision long cadence photometry obtained by space craft. Combin…
KIC 2557430: A Triple System Containing One Gamma Dor and Two Flaring Components?
Ceren Kamil, Hasan Ali Dal
The results are presented for eclipsing binary KIC 2557430. The mass ratio was computed as 0.868+-10.002, while the inclination (i) was found as 69.75+-0.01 deg with T2=6271+-1 K.…
