Asteroseismic Investigation of 20 Planet and Planet-Candidate Host Stars

C. Kayhan, M. Yıldız, Z. Çelik Orhan

Planets and planet candidates are subjected to great investigation in recent years. In this study, we analyse 20 planet and planet-candidate host stars at different evolutionary ph…

Asteroseismic analysis of 15 solar-like oscillating evolved stars

Z. Çelik Orhan, M. Yıldız, C. Kayhan

Asteroseismology using space-based telescopes is vital to our understanding of stellar structure and evolution. {\textit{CoRoT}}, {\textit{Kepler}}, and {\textit{TESS}} space teles…

Fundamental properties of solar-like oscillating stars from frequencies of minimum : II. Model computations for different chemical compositions and mass

M. Yıldız, Z. Çelik Orhan, C. Kayhan

The large separations between the oscillation frequencies of solar-like stars are measures of stellar mean density. The separations have been thought to be mostly constant in the o…

On the structure and evolution of planets and their host stars effects of various heating mechanisms on the size of giant gas planets

M. Yıldız, Z. Çelik Orhan, C. Kayhan +1

It is already stated in the previous studies that the radius of the giant planets is affected by stellar irradiation. The confirmed relation between radius and incident flux depend…

Fundamental properties of Kepler and CoRoT targets: III. Tuning scaling relations using the first adiabatic exponent

M. Yıldız, Z. Çelik Orhan, C. Kayhan

So called scaling relations have the potential to reveal the mass and radius of solar-like oscillating stars, based on oscillation frequencies. In derivation of these relations, it…

Dynamical parallax, physical parameters and evolutionary status of the components of the bright eclipsing binary α Draconis

K. Pavlovski, C. A. Hummel, A. Tkachenko +13

Altough both components of the bright eclipsing binary Dra having been resolved using long baseline interferometry and the secondary component shown to contribute some 15\% of…
