C IN O Fe Mg Ba 562.27 Eu 630.52 logo are the solar values for each element in a box of 1012 H.We observe a metal-poor star (RA, DEC) = (14:02:31.84, +09:41:09.94), we refer to as Star A, with a high resolution (R = 60,000) spectrograph. We find the following elemental abundances in this star: [Fe/H] = -2.64, [C/Fe] = -0.28, [O/Fe] = 0.78, [Mg/Fe] = 0.47, [Eu/Fe] = 0.20, [Ba/Fe] = 0.25, . (45pts) A. What is the (formal) velocity resolution of our spectrograph? (3pts) B. Given the abundances of the star and the sun compute for [X/H] abundance for Star A for each element (in table format) (12 pts) C. Given the abundances of the star and the sun compute for log & abundance for each element in Star A (in table format) (12 pts) D. Calculate the actual number ratio n(X)(H) in the star for each element (12pts) E. Assuming that [N/Fe] = +1.13, What is this star's [C+N/Fe] ? (3pts) F. Is this star observable from upcoming European Extremely Large Telescope ? (3pts)
