Asteroseismology and interferometry of the red giant star <i>ϵ</i> Ophiuchi
The GIII red giant star <i>ϵ<i/> Oph has been found to exhibit several modes of oscillation by the MOST mission. We interpret the observed frequencies of oscillation in terms of theoretical radial <i>p<i/>-mode frequencies of stellar models. Evolutionary models of this star, in both shell H-burning and core He-burning phases …
