Abstract
A powerful tool in the study of cool stars and brown dwarfs is broad wavelength spectroscopy. Recently, a spectral sequence was established between 6300 and 9000 Å for dwarfs ranging in type from K5 to M9. With today’s technology, classification spectra can also be obtained with relative ease in the region near peak flux (0.9 – 2.4μm). A re-establishment of spectral types in the infrared will allow very red dwarfs to be classified using shorter integration times at smaller telescopes. In particular, the resulting 0.6 – 2.4 μm spectra will provide important physical information for the latest M dwarfs and for brown dwarf candidates.
