Karla Ziboney Arellano University of Edinburgh, Institute for N Cordova Astronomy ------------------------------------------------------------------------------------ Abstract 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. This is due, in large part, to the lack of strong C emission lines in the optical regime, which has made carbon abundance measurements in HII regions, despite their clear astrophysical importance, relatively rare. To complicate matters futher, there exists an unresolved discrepancy (the abundance discrepancy factor; ADF) between the two methods of deriving accurate abundances: the collisionally-excited emission lines (CELs) method and the recombination emission lines (RLs) method. Because the optical RLs are intrinsically very faint, there is only a small collection of extragalactic HII regions for which O/H abundances from RLs and, subsequently, the O ADF can be determined, while little to no ADF studies of other elements exist. Fortunately, HST provides the opportunity to observe the UV CIII] 1907, 1909 and OIII] 1666 CELs. We request 20 orbits of COS G160M+G185M spectra of 10 HII regions in M33 and M101 with optical C RL detections. We will measure the UV C and O CELs, determine robust C/O abundances and gradients, measure the ionizing massive star population properties, and, combined with the existing RLs, provide a novel pathway to accessing the ADF with C. Owing to their different nucelosynthetic pathways and emission sensitivies, we will be able to compare the O and C ADFs for these 10 regions relative to their gaseous and stellar properties and constrain the source of the ADF; this will be the first coherent UV+optical C+O ADF analysis of its kind. ------------------------------------------------------------------------------------ Observations Description ------------------------ The observational goal of our program is to use the Cosmic Origins Spectrograph to obtain measurements of the O III] 1666 and C III] 1907, 1909 emission lines in 10 H II regions in M101 and M33, spanning a large range in metallicity and disk radius. Target Acquisition: We have excellent H-alpha narrow-band and R-band astrometry (Massey+07), allowing us to center our COS observations on the regions of highest surface brightness in H-alpha. However, due to the proximity of M101 17494( 12) - 12-Nov-2024 21:07:07 - [ 2] and M33, the large H II regions fill the COS aperture, making centering on the nebular peak difficult. Instead, we will use the efficient target image acquisition method of a pointing offset from a nearby bright star. We used the Guide Star Catalog 2.3 and GAIA to select offset stars within 1' of the target H II regions. COS Spectra: We will use the G160M grating with the 1533 setting, allowing simultaneous coverage of all the necessary stellar features to constrain the the properties of the ionizing massive star population population and the O III] 1666 emission line. While some past programs targeting O III] 1666 in very nearby targets have suffered from contamination by the Milky Way Al II 1671 absorption feature, the high spectral resolution of G160M will ensure that the proposed O III] 1666 observations are cleanly separated. Additionally, we will use the G185M grating with the 2010 setting to cleanly center the C III] 1907, 1909 in the highest- sensitivity portion of the NUV strips. ------------------------------------------------------------------------------------ 17494( 12) -
