λBoötis Stars
Published online by Cambridge University Press: 14 August 2015
Extract
This group of metal poor stars were introduced with the identification of an ‘abnormal’ spectrum for λBoõtis in the famous classification survey of Morgan, Keenan & Kellman (1943) based on a blue sensitive photographic emulsion. More stars were discovered with comparable spectra and with other peculiarities, in particular when the available spectral region was extended to the red and beyond the optical region towards the IR and to the UV.
