Scientific paper

A dispersion IUE spectrum of the hydrogen Ly-alpha emission line of the nearby late-type star Beta Gem is presented. Values are determined for the density, velocity, dispersion, and bulk velocity of the interstellar H I toward the star, showing agreement with previous IUE results for stars in the same general direction (Murthy et al., 1987). It is shown that the interstellar medium in the line of sight to Beta Gem has a total column density of about 2 x 10 to the 18th/sq cm and a velocity dispersion of 13-16 km/s. The flow vector is in agreement with the interstellar wind found by Crutcher (1982).
