M67 Blue Stragglers with High-resolution Infrared Spectroscopy
K. E. Brady, C. Sneden, C. A. Pilachowski +5
We report on the first detailed infrared chemical analysis of five binary members (S277, S997, S975, S1031, and S1195) in the open cluster M67 (NGC 2682). These stars are located o…
Chemical Compositions of Red Giant Stars in the Old Open Cluster NGC 7789
Neel Nagarajan, Christopher Sneden, Melike Afsar +1
We have gathered optical-region spectra, derived model atmosphere parameters, and computed elemental abundances for 15 red giant stars in the open cluster NGC 7789. We focus on the…
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…
