Local stellar kinematics from RAVE data: IV. Solar neighbourhood age-metallicity relation
S. Duran, S. Ak, S. Bilir +4
We investigated the age-metallicity relation using a sample of 5691 F and G type dwarfs from RAVE DR3 by applying several constraints: i) We selected stars with surface gravities l…
On the eclipsing cataclysmic variable star HBHA 4705-03
A. Rutkowski, T. Ak, T. R. Marsh +1
We present observations and analysis of a new eclipsing binary HBHA 4705-03. Using decomposition of the light curve into accretion disk and hot spot components, we estimated photom…
First identification and absolute magnitudes of the red clump stars in the Solar neighbourhood for WISE
E. Yaz Gokce, S. Bilir, N. D. Ozturkmen +4
We present the first determination of absolute magnitudes for the red clump (RC) stars with the Wide-field Infrared Survey Explorer (WISE). We used recently reduced parallaxes take…
A New Absolute Magnitude Calibration for Red Clump Stars
S. Bilir, T. Ak, S. Ak +2
We present an M_V absolute magnitude calibration including the B-V colour and [Fe/H] metallicity for the red clump stars in the globular and open clusters with a wide range of meta…
