Description
The column density distribution of the local interstellar medium (LISM) towards a sample of 15 fast rotators observed with IUE at high resolution is reported. The targets are closer than 200 pc, and most of them have lines of sight not previously investigated. Hydrogen column densities are inferred using zinc, known to be little depleted. The results are in general agreement with the broad picture of the LISM drawn by Paresce (1984), with the possible exception of some cases which are discussed. For the few stars for which long-wavelength images were available the Mg II/Mg I ratio is derived to obtain information on the temperature of the gas in the line of sight.

    The Large Interferometer For Exoplanets (LIFE) is a proposed space mission that enables the spectral characterization of the thermal emission of exoplanets in the solar neighborhood. The mission is designed to search for global atmospheric biosignatures on dozens of temperate terrestrial exoplanets and it will naturally investigate the diversity of
