Local stellar kinematics from RAVE data: II. Radial Metallicity Gradient
B. Coskunoglu, S. Ak, S. Bilir +5
We investigate radial metallicity gradients for a sample of dwarf stars from the RAdial Velocity Experiment (RAVE) Data Release 3 (DR3). We select a total of approximately 17000 F-…
Transformations between WISE, 2MASS, SDSS and BVRI photometric systems: I. Transformation equations for dwarfs
S. Bilir, S. Karaali, S. Ak +5
We present colour transformations for the conversion of the W1 and W2 magnitudes of WISE photometric system to the Johnson-Cousins' BVRI, SDSS (gri), and 2MASS (JHK_s) photometric…
Study of Eclipsing Binary and Multiple Systems in OB Associations: I. Ori OB1a - IM Mon
H. Bakis, V. Bakis, S. Bilir +5
All available photometric and spectroscopic observations were collected and used as the basis of a detailed analysis of the close binary IM Mon. The orbital period of the binary wa…
An Improved Metallicity Calibration with UBV Photometry
S. Karaali, S. Bilir, S. Ak +2
We used the data of 701 stars covering the colour index interval 0.32<B-V<=1.16, with metallicities -1.76<=[Fe/H]<=+0.40 dex, which were taken from PASTEL catalogue and estimated m…
Local Stellar Kinematics from RAVE Data: I. Local Standard of Rest
B. Coskunoglu, S. Ak, S. Bilir +19
We analyze a sample of 82850 stars from the RAVE survey, with well-determined velocities and stellar parameters, to isolate a sample of 18026 high-probability thin-disc dwarfs with…
Transformations between 2MASS, SDSS and BVI photometric systems for late-type giants
E. Yaz, S. Bilir, S. Karaali +3
We present colour transformations from Two Micron All Sky Survey (2MASS) photometric system to Johnson-Cousins system and to Sloan Digital Sky Survey (SDSS) system for late-type gi…
