Spectroscopy, Stars: Late-Type
Scientific paper
We present a library of Utrecht echelle spectrograph (UES) observations of a sample of F, G, K and M field dwarf stars covering the spectral range from 4800Å to 10600Å with a resolution of 55000. These spectra include some of the spectral lines most widely used as optical and near-infrared indicators of chromospheric activity such as Hβ, MgI b triplet, NaI D{1}, D{2}, HeI D{3}, Hα, and CaII IRT lines, as well as a large number of photospheric lines which can also be affected by chromospheric activity. The spectra have been compiled with the aim of providing a set of standards observed at high-resolution to be used in the application of the spectral subtraction technique to obtain the active-chromosphere contribution to these lines in chromospherically active single and binary stars. This library can also be used for spectral classification purposes. A digital version with all the spectra is available via ftp and the World Wide Web (WWW) (http://www.ucm.es/OTROS/Astrof/fgkmsl/UESfgkmsl.html) in FITS format. (6 data files).
