31 Aug 1997 | Subject: | astro-ph | Affiliation: | 1,2), E.L. Martin (3,4) ( Dept. Astrofisica UCM, Pennsylvania State University, Instituto de Astrof’{i}sica de Canarias, University of California at Berkeley | Abstract: | 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 4800 AA to 10600 AA 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 H_beta, Mg I b triplet, Na I D_1, D_2, He I D_3, H_alpha, and Ca II 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) in both ASCII and FITS formats. | Source: | arXiv, astro-ph/9709004 | Services: | Forum | Review | PDF | Favorites |
