New intrinsic-colour calibration for -- photometry
Yuksel Karatas, William J. Schuster
A new intrinsic-colour calibration (----) is presented for the -- photometric system, making use of re-calibrated Hipparcos parallaxes and published reddeni…
CCD BV and 2MASS photometric study of the open cluster NGC 1513
S. Bilir, T. Guver, I. Khamitov +5
We present CCD BV and JHK 2MASS photometric data for the open cluster NGC 1513. We observed 609 stars in the direction of the cluster up to a limiting magnitude of …
The age of cataclysmic variables: a kinematical study
T. Ak, S. Bilir, S. Ak +2
Using available astrometric and radial velocity data, the space velocities of cataclysmic variables (CVs) with respect to Sun were computed and kinematical properties of various su…
A Universal Vertical Stellar Density Distribution Law for the Galaxy
S. Karaali, E. Hamzaoglu, S. Bilir
We reduced the observational logarithmic space densities in the vertical direction up to 8 kpc from the galactic plane, for stars with absolute magnitudes (5,6], (6,7] and [5,10] i…
Estimation of Galactic Model Parameters and Metalicity Distribution in Intermediate Latitudes with SDSS
E. Yaz, S. Karaali
We estimated the galactic model parameters for a set of 20 intermediate-latitude fields with galactic longitudes 0<l<100 and 160<l<240, included in the currently available Data Rel…
SDSS Absolute Magnitudes for Thin Disc Stars based on Trigonometric Parallaxes
S. Bilir, S. Karaali, S. Ak +3
We present a new luminosity-colour relation based on trigonometric parallaxes for thin disc main-sequence stars in SDSS photometry. We matched stars from the newly reduced Hipparco…
