## [38.07] Analysis of EUV Spectra of Cool Stars

A. K. Dupree (CfA)

Spectrometers on board EUVE are obtaining stellar spectra in the extreme ultraviolet region that contain a wealth of unique information about atmospheres of cool stars. EUVE spectra of the RSCVn binary system Capella (HD~34029; G8 III $+$ G0 III) are presented in this session (Dupree, Doschek, Green, \&\ Raymond, EUVE Spectra of Capella (Alpha Aurigae), Bull. AAS, this volume). In addition, updated calculations of coronal ionization equilibrium (Brickhouse, Raymond, \&\ Smith, Bull. AAS, this volume) increase the confidence of the analysis. These spectra and calculations will be used to illustrate major scientific questions that can be addressed through EUV spectroscopy: what is the distribution of temperature and emission measure in the atmosphere of the system? what are the atmospheric densities? are non-equilibrium ionization processes present? is there evidence for a stellar wind? \end {abstract}
