While oxygen and nitrogen have been widely observed in spiral and dwarf galaxies, the study of the next most abundant element, carbon, resides in a state of relative infancy. We propose to use COS on the HST to observe UV emission lines of carbon and oxygen for a sample of high-surface brightness low-metallicity dwarf galaxies. Combining these data with the observations of Garnett et al. (1995), we will produce the first statistically significant sample of C/O abundances in nearby dwarf galaxies. The upgrade in UV efficiency from FOS to COS and the large pool of spectra available today due to extensive surveys (e.g., the SDSS), allow us to efficiently triple the number of secure measurements. Determining the underlying trend of C with O and the scatter in C/O at a given value of O/H provide strong constraints on the nucelosynthetic origin of C. In addition, combining these data with ground-based optical spectra will show how carbon and nitrogen production are coupled, providing key insights as to the degree that carbon is a primary product of intermediate-mass stars. Given the recent interest in possibilities of non-universal initial mass functions in low-mass (low-metallicity) galaxies, a secure characterization of the behavior of C/O is vital. We will use COS with the G140L grating and a central wavelength of 1280 angstroms in order to obtain new measurements of the emission lines OIII] 1661,1666 and CIII] 1907,1909 over the wavelength range of 1282 to 2148 angstroms for detector segment A in a sample of extragalactic HII regions. Detector segment B extends down to lower wavelengths, but provides limited sensitivity, so any lines detected in this wavelength range will be a bonus. We will observe 11 of our targets for 1 orbit and 1 additional target for 2 orbits with the FUV channel G140L grating through the PSA. This allows us to maxmize science per orbit by fitting most target observations into a single orbit. In order to establish the C/O relationship with O/H in the sparsely measured metal poor regime, our targets were chosen for their high emission line surface brightnesses, high optical ionizations, and low metallicites (12+log(O/H)<8.2). Further, we chose only the most compact of these targets in order to achieve maximum flux through the 2.5" COS aperture. The additional target that requires 2 orbits was chosen because it greatly increases the significance of our sample by extending the O abundance range 0.14 dex down to 12+log(O/H)=7.28. We have chosen to use COS in TIMETAG mode since our targets do not reach count rate limits, and TIMETAG mode provides higher data quality. We will use the G140L grating at the central wavelength position of 1280 angstroms for all exposures because this setup provides excellent wavelength coverage, which allows simultaneous observations of all the necessary UV emission lines. With excellent input coordinates for our sample from the SDSS, our observing plan is to center on our targets using the ACQ/PEAKXD and ACQ/PEAKD mode in the FUV G130M grating at a center wavelength of 1291 angstroms. The spatial resolution of the COS FUV G130M grating is 0.5-1.5", and so more closely mimicks the resolution of previous measurements with the SDSS. We use SCAN-SIZE=3, STEP-SIZE=1.3, and CENTER=FLUX-WT for the ACQ/PEAKD mode assuming an extended source, which is recommended in the COS Handbook when a faster TA is required and lower centering accuracy can be tolerated. To keep acquisition exposure times short, each acquisition was determined using a flat continuum, GALEX FUV magnitudes, and a relaxed requirement of S/N=25. Then, all remaining time was allocated to observing each target for the remainder of the orbit. Input GALEX FUV magnitudes/arcsec^2 were determined by first subtracting the diffuse emission of extended sources from the central aperture of ~5", where 5" is approximately the FWHM PSF of GALEX. We then assumed the flux within the GALEX 5" aperture is equivalent to the ~2" FWHM PSF of the SDSS. Since our targets all appear to be compact objects with sizes of ~2" in SDSS images, this is a reasonable assumption. We then divided the GALEX FUV magnitudes by the area of the 2" PSF to determine the FUV magnitude/arcsec^2. For acquistion images, no diffuse emission was subtracted, as we only care about finding the brightest region to center our observation on, and would like to reduce acquisition exposure time. For our FUV G140L configuration, no flats are available and so we use FP-POS=ALL, which takes 4 images offset from one another in the dispersion direction and increases S/N . This 4 positions also allow a flat to be created and cosmic rays to be eliminated.
