[68.17] Spectroscopic Analysis of Volatile Elements

E. Manrao, D. Fischer (SFSU)

We have performed spectral synthesis modeling to measure carbon and oxygen abundances for 297 stars from the Lick and AAT planet search surveys. Of these stars, 27 have known planetary companions and 270 are without detected planets. The abundance of these volatile elements is compared for stars with and without planetary companions, extending the analysis of Fischer & Valenti (2005).
