High-Resolution Infrared Spectroscopy of the Dust-Obscured Metal-Poor Open Cluster Trumpler 5
S. Özdemir, M. Afşar, C. Sneden +8
Trumpler 5 is a moderately old, dust-obscured metal-poor open cluster. In this study, high-resolution near-infrared spectroscopic data of seven giant stars from the Trumpler 5 clus…
Effective Temperature Estimations from Line Depth Ratios in the \H\ and \K-band Spectra of IGRINS
Melike Afşar, Zeynep Bozkurt, Gamze Böcek Topcu +5
Determining accurate effective temperatures of stars buried in the dust-obscured Galactic regions is extremely difficult from photometry. Fortunately, high-resolution infrared spec…
The Active Chromospheres of Lithium-Rich Red Giant Stars
Christopher Sneden, Melike Afsar, Zeynep Bozkurt +17
We have gathered near-infrared -band high resolution spectra of nearly 300 field red giant stars with known lithium abundances in order to survey their \species{He}{i} 1083…
Chemical Compositions of Red Giant Stars from Habitable Zone Planet Finder Spectroscopy
Christopher Sneden, Melike Afsar, Zeynep Bozkurt +15
We have used the Habitable Zone Planet Finder (HPF) to gather high resolution, high signal-to-noise near-infrared spectra of 13 field red horizontal-branch (RHB) stars, one open-cl…
Chemical Compositions of Evolved Stars From Near-Infrared IGRINS High-Resolution Spectra. I. Abundances in Three Red Horizontal Branch Stars
Melike Afşar, Christopher Sneden, Michael P. Wood +6
We have derived elemental abundances of three field red horizontal branch stars using high-resolution (R 45,000), high signal-to-noise ratio (S/N 200) and …
A Spectroscopic Survey of Field Red Horizontal-Branch Stars
Melike Afşar, Zeynep Bozkurt, Gamze Böcek Topcu +3
A metallicity, chemical composition, and kinematic survey has been conducted for a sample of 340 candidate field red horizontal branch stars. High resolution, high signal-to-noise…
Photometric Solutions of Some Contact ASAS Binaries
I. Gezer, Z. Bozkurt
We present the first light curve solution of 6 contact binary systems which are chosen from the ASAS catalog. The photometric elements and the estimated absolute parameters of all…
The WISE View of RV Tauri Stars
I. Gezer, H. Van Winckel, Z. Bozkurt +4
We present a detailed study based on infrared photometry of all Galactic RV Tauri stars from the General Catalogue of Variable Stars (GCVS). RV Tauri stars are the brightest among…
