摘要: Rotational velocities as well hydrogen and helium line intensities of one hundred twelve members the Scorpio-Centaurus association have been derived. For stars withM v 0·0, all which are found in dense upper Scorpius region, rotate much faster than their counter-parts amongst field stars, Pleiades Alpha-Persei cluster members.
