PI: Dr. Ruth C. Peterson Astrophysical Advances ------------------------------------------------------------------------------------ Abstract We propose a novel approach towards defining the intital carbon abundance of extremely metal-poor stars. We will observe the C I 1930.9A line, which is detectable in unevolved turnoff stars even for [Fe/H] < -3.0. COS 1941A spectra and ground-based echelle spectra of the CH bands at 3142A and 4315A will both be analyzed with theoretical spectral calculations, and the results compared to understand better the effect of atmospheric convective motions on the CH features normally used for carbon determinations. Because the low-excitation C I 1930.9A line is virtually immune from non-LTE effects, the results should place the carbon abundances of these stars on a firm footing, of importance for theoretical scenarios of single star formation at these low metallicities. ------------------------------------------------------------------------------------ Observations Description ------------------------ We will determine the carbon abundance of five extremely metal-poor stars from the C I line at 1903.9A, using near-UV spectra obtained in this program. These, and ground-based echelle spectra of the CH bands at 3142A and 4315A, will be analyzed by overplotting theoretical spectral calculations broadened by the appropriate the instrumental resolution.
