Absolute Dimensions and Apsidal Motion of the Young Detached System LT Canis Majoris
V. Bakis, I. Bulut, S. Bilir +3
New high resolution spectra of the short period (P~1.76 days) young detached binary LT CMa are reported for the first time. By combining the results from the analysis of new radial…
Interrelated Main-Sequence Mass-Luminosity, Mass-Radius and Mass-Effective Temperature Relations
Z. Eker, V. Bakis, S. Bilir +7
Absolute parameters of 509 main-sequence stars selected from the components of detached-eclipsing spectroscopic binaries in the Solar neighbourhood are used to study mass-luminosit…
Study of Eclipsing Binary and Multiple Systems in OB Associations V: MQ Cen in Crux OB1
V. Bakis, Z. Mikulasek, J. Janik +6
The early-type massive binary MQ Cen (P=3.7 d) has been investigated by means of high-resolution () spectral analysis and multi-band (Johnson and Strö…
Absolute Dimensions and Apsidal Motion of the Eccentric Binary V731 Cephei
V. Bakis, M. Zejda, I. Bulut +7
A detailed analysis of new and existing photometric, spectroscopic and spatial distribution data of the eccentric binary V731 Cep was performed. Spectroscopic orbital elements of t…
Modelling the components of binaries in Hyades: The dependence of the mixing-length parameter on stellar mass
M. Yildiz, K. Yakut, H. Bakis +1
We present our findings based on a detailed analysis for the binaries of the Hyades, in which the masses of the components are well known. We fit the models of components of a bina…
Study of Eclipsing Binary and Multiple Systems in OB Associations II. The Cygnus OB Region: V443 Cyg, V456 Cyg and V2107 Cyg
V. Bakis, H. Hensberge, S. Bilir +6
Three presumably young eclipsing binary systems in the direction of the Cygnus OB1, OB3 and OB9 associations are studied. Component spectra are reconstructed and their orbits are d…
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…
The Spectroscopic Orbits of Three Double-lined Eclipsing Binaries: I. BG Ind, IM Mon, RS Sgr
V. Bakis, H. Bakis, S. Bilir +7
We present the spectroscopic orbit solutions of three double-lines eclipsing binaries, BG Ind, IM Mon and RS Sgr. The first precise radial velocities (RVs) of the components were d…
Study of Eclipsing Binary and Multiple Systems in OB Associations IV: Cas OB6 Member DN Cas
V. Bakis, H. Bakis, S. Bilir +1
An early-type, massive, short-period () eclipsing spectroscopic binary DN Cas has been re-visited with new spectral and photometric data. The masses a…
A catalog of chromospherically active binary stars (third edition)
Z. Eker, N. Filiz Ak, S. Bilir +8
Chromospherically Active Binaries (CAB) catalogue have been revised and updated. With 203 new identifications, the number of CAB stars is increased to 409. Catalogue is available i…
