Unravelling Mass Transfer in Algols from Surface Abundances. I. Z Vulpeculae
Ahmet Dervişoğlu, Simge Adalalı, Ferhat Güney +7
The photospheric abundance pattern of the components is a sensitive probe of mass and angular momentum transfer in Algols. With the aim to trace the evolutionary history and disclo…
Spectral Disentangling Reveals Deep CNO-cycle Exposure in ET Cru
Gökhan Yücel, Volkan Bakış, Christian Nitschelm +2
Binary stars undergoing mass transfer provide unique laboratories for testing stellar evolution. Here, we present a comprehensive photometric and spectroscopic analysis of the semi…
Decoding the RVb Enigma of DF Cyg: Pulsations, Circumstellar Disks, and Post-RGB Evolution Revealed by Multi-Wavelength Observations
Cenk Kayhan, Timur Şahin
This investigation integrates five decades of ground-based photometric data from the AAVSO, AFOEV, ASAS, ASAS-SN, and SuperWASP surveys with recently acquired TESS observations, co…
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…
An Updated Line List for Spectroscopic Investigation of G Stars II: Refined Solar Abundances via Extended Wavelength Coverage to 10 000 Å
T. Şahin, F. Güney, S. A. Şentürk +2
This study introduces a line list for the abundance analysis of F and G type stars across the 4080-9675 A wavelength range. A systematic search employing lower excitation potential…
Spectroscopic and Dynamic Orbital Analyses of Metal-Poor and High Proper Motion Stars: I. HD\,8724 and HD\,195633
M. Marismak, T. Sahin, F. Guney +2
In this study, spectral, age, kinematic, and orbital dynamical analyses were conducted on metal-poor and high proper-motion (HPM) stars, HD 8724 and HD 195633, selected from the So…
Hyperfine Structure Investigation of Singly Ionized Thulium in FT Spectra
T. Y. Kebapci, S. Parlatan, S. Sert +7
The hyperfine structure of 40 spectral lines of singly ionized thulium (Tm II) in emission spectra from a hollow cathode discharge lamp measured with a Fourier transform spectromet…
An Updated Line List for Spectroscopic Investigation of G Stars- I: Redetermination of the Abundances in the Solar Photosphere
T. Sahin, M. Marismak, N. Cinar +1
We propose a line list that may be useful for the abundance analysis of G-type stars in the wavelength range 4080 -- 6780 A. It is expected that the line list will be useful for su…
