Metallicities and ages of stellar populations at a high Galactic latitude field
Michael H. Siegel, Yuksel Karatas, I. Neill Reid
We present an analysis of data from the Selected Area SA 141. By applying recalibrated methods of measuring ultraviolet excess (UVX), we approximate abundances and absolute…
The Metallicity Distribution of Distant F and G type stars in the CFHT Legacy Survey Deep Field
Y. Karatas, M. Kilic, O. Gunes +1
We study the metal abundances of F and G type stars in the Galactic disk and halo using the Canada-France-Hawaii Telescope Legacy Survey D4 field. For a sample of stars within 7 kp…
Dynamical evolution of active detached binaries on log Jo - log M diagram and contact binary formation
Z. Eker, O. Demircan, S. Bilir +1
Orbital angular momentum (Jo), systemic mass (M) and orbital period (P) distributions of chromospherically active binaries (CAB) and W Ursae Majoris (W UMa) systems were investigat…
Evidences on secular dynamical evolution of detached active binary orbits and contact binary formation
Z. Eker, O. Demircan, S. Bilir +1
Evidence of secular dynamical evolution for detached active binary orbits are presented. First order decreasing rates of orbital angular momentum (OAM), systemic mass ($M=M_{1}+M_{…
Mass loss and orbital period decrease in detached chromospherically active binaries
O. Demircan, Z. Eker, Y. Karatas +1
The secular evolution of the orbital angular momentum (OAM), the systemic mass and the orbital period of 114 chromospherically active binaries (CABs) were investi…
Galactic model parameters for field giants separated from field dwarfs by their 2MASS and V apparent magnitudes
S. Bilir, S. Karaali, T. Guver +2
We present a procedure which separates field dwarfs and field giants by their 2MASS and V apparent magnitudes. The procedure is based on the spectroscopically selected standards, h…
