Identification of λ Bootis stars using IUE spectra. II. High resolution data.
SOLANO E. and PAUNZEN E.
Abstract (from CDS):
Stars included in the catalogue of λ Bootis stars by Paunzen et al. (1997) with high resolution spectra (FWHM: 0.10-0.25Å) in the INES Archive of the International Ultraviolet Explorer satellite (IUE) are analyzed here in order to establish membership criteria for the λ Bootis group. Line-ratios of carbon to heavier elements (Si, Al, Ca) were adopted as criteria in the SWP range (1150-1980Å). For the LWP range (1850-3350Å), the intensity of metallic lines (Fe and Mg) was used. These criteria, together with those derived for low resolution spectra, make the IUE Final Archive a powerful tool to find new λ Bootis candidates.
