Comprehensive Gaia DR3-Based Astrometric, Photometric, and Kinematic Studies of the Binary Open Cluster and Persei
Seval Taşdemir, Waleed Elsanhoury, Deniz Cennet Çınar +2
In the Gaia era, a comprehensive analysis of the binary open clusters NGC 869 (h Persei) and NGC 884 (chi Persei) system has been conducted to investigate its structural, astrophys…
V570 Per: Characterization of a Benchmark Eclipsing Binary
Gökhan Yücel, Neslihan Alan, Timothy Banks +3
This study presents a comprehensive analysis of the detached binary system V570\,Per through combined photometric, spectroscopic, and astrometric observations. By disentangling the…
Empirical Bolometric Correction and Zero-Point Constants of Visual Magnitudes from High-Resolution Spectra
Gökhan Yücel, Selçuk Bilir, Volkan Bakış +1
A method of obtaining bolometric corrections () from observed high-resolution, high- spectra is described. The method is applied to spectra of 128 stars collected…
Selected Cephei pulsators in eclipsing binaries
O. Cakirli, B. Hoyman, O. Ozdarcan +1
We present a comprehensive analysis of five eclipsing binary systems containing Cephei-type pulsating components. These systems were identified using the high-precision Transit…
A Comprehensive Study of Czernik 41 and NGC 1342 Using CCD UBV and Gaia DR3 Data
B. Tanik Ozturk, S. Bilir, T. Yontan +5
In this study, the structural, astrophysical, kinematic, and Galactic orbital parameters of the open clusters Czernik 41 and NGC 1342, as well as their dynamical evolution, are inv…
A Multi-Data Approach to Open Clusters: Roslund 3 and Ruprecht 174 in CCD UBV and Gaia DR3 Context
H. Karagoz, T. Yontan, S. Bilir +5
A detailed analysis of the structural, astrophysical, kinematic, and dynamical properties of the open clusters Roslund 3 and Ruprecht1 74 is carried out using CCD UBV photometry in…
Stellar Ancestry Unlocked: Chemical and Orbital Clues Link Metal Poor Stars to Globular Clusters and the Galaxy's Thick Disk
Gizay Yolalan, Timur Şahin, Selçuk Bilir +1
This study presents a detailed chemical, kinematic, and orbital dynamic analysis of five metal poor stars in the solar neighborhood: HD 2665, HD 5916, HD 122956, HD 189349, and HD…
Tracing the Galactic Origins of Selected Four G-type Stars in the Solar Neighbourhood
Deniz Cennet Çınar, Selçuk Bilir, Timur Şahin +1
We present a multi-method investigation of four metal-poor G-type main-sequence stars to resolve their Galactic origins. By combining high-resolution spectroscopy from PolarBase, p…
Exploring the empirical instability strip for Dor-type stars in eclipsing binaries
O. Cakirli, B. Hoyman, O. Ozdarcan +1
This research paper has light curve modelling, spectroscopy, and detailed asteroseismic studies for five detached eclipsing binaries with a Dor component that have been found s…
Kinematics of Cataclysmic Variables in the Solar Neighborhood in the Gaia Era
R. Canbay, T. Ak, S. Bilir +2
Using high-precision astrometric data from Gaia DR3 and updated systemic velocities from the literature, kinematical properties of cataclysmic variables (CVs) were investigated. By…
Unveiling the Origins and Dynamics of the Hierarchical Triple Star System CN Lyn
G. Yucel, V Bakis, R. Canbay +3
In this study we present a detailed analysis of CN Lyn, an overlooked triple star system, by combining spectroscopic data from the literature, photometric \textit{TESS} data, and k…
