为了确定太阳型恒星之间的变异性，用精密测光技术观测了昂宿星团和毕宿星团中的年轻主序恒星，以及北极点附近Malmquist场中的老盘星。在44颗参宿四恒星中，至少有5颗，甚至可能是10颗，而且可能是Malmquist场中41颗恒星中的一颗，它们的光谱类型都是F8V-K2V。
The young main sequence stars in the Pleiades and Hyades clusters, and old disk stars in the Malmquist Field near the north galactic pole, have been observed by precision photometry in order to determine the prevalance of variability among solar type stars. Significant variations have been found in at least five, and possibly ten, of 44 Hyades stars, and possibly one of the 41 stars in the Malmquist Field, all of which are of spectral type F8 V-K2 V.
