标题： Absolute magnitudes and kinematics of CP stars from Hipparcos data

摘要： 使用LM方法(Luri等，1996)获得了上主序星不同类型的CP星在HR图中的位置和运动学特征。 大多数CP星是占据整个序列宽度的主序星。 从运动学角度来看，它们属于年轻的盘星族（年龄<1.5 Gyr）。 还发现，从运动学的角度来看，lambda Bootis星的行为与同一光谱范围内的正常恒星相似。 另一方面，roAp和noAp星表现出相同的运动学特征。 特殊速度分布函数被分解为三个维度的高斯函数，并明确确立了毕宿星团、天狼星和毕星团运动集团的存在。 最后，发现少量的CP星是高速天体。 显示英文摘要

摘要： The position in the HR diagram and the kinematic characteristics of different kinds of CP stars of the upper main sequence are obtained using the LM method (Luri et al., 1996). Most of the CP stars are main sequence stars occupying the whole width of the sequence. From a kinematic point of view, they belong to the young disk population (ages < 1.5 Gyr). It has also been found that, on kinematic grounds, the behaviour of lambda Bootis stars is similar to the one observed for normal stars of the same spectral range. On the other hand, roAp and noAp stars show the same kinematic characteristics. The peculiar velocity distribution function has been decomposed into a sum of three dimensional gaussians and the presence of Pleiades, Sirius and Hyades moving groups has been clearly established. Finally, a small number of CP stars are found to be high-velocity objects.
