High Resolution Spectroscopy Of The Hyades Giants, Antonio Martinez

Electronic Thesis and Dissertation Repository

The four K0IIIHyades red clump giants, γ , δ , ϵ , and θ 1Tauri, are ideal candidates for cool star research. They are easily observable at a distance of only 47 pc and one star, ϵ Tauri, is a suspected Maunder minimum star. These stars also provide a useful opportunity to investigate the nature of the photospheric velocity field, and assess the effectiveness of a range of spectroscopic tools including the merits of the microturbulence-macroturbulence approach to the study of cool star spectra. High resolution (λ /Δ λ ∼ 100,000) exposures, taken from January 2001 to October 2008 in …
