Abstract

    One of the most effective ways to measure the rotational velocity of celestial bodies, study their broadening of spectral lines. Here we describe how to record the spectrum of the star, the lion's tail. The spectral lines of the star factors influencing the broadening of spectral lines, we compute rotational velocity of Denebola.
