The structure and evolution of the Galactic high- disc I. Chemical and age orbital cartography
Furkan Akbaba, Danny Horta, Olcay Plevne
We present a comprehensive chemical and age orbital cartography of the Galactic high- disc using subgiant stars with precise ages, element abundances, and full phase-space info…
Estimating Initial Mass of Gaia-Enceladus Dwarf Galaxy with Chemical Evolution Model
Olcay Plevne, Furkan Akbaba
This work investigates the initial mass and chemical evolution history of the Gaia-Enceladus dwarf galaxy. We combine spectroscopic data from APOGEE with astrometric data from Gaia…
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 Åahin, 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 Ãınar, Selçuk Bilir, Timur Åahin +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…
