摘要
我们对λBootis群的所有成员进行了可用的Hipparcos历元光度分析。除了已知的δ Scuti脉动频率外，我们还搜索了由双星或旋转引起的变化引起的日食。hd15165的已知频率被确认为另一个较低的单频率，这可能是由吸积事件引起的。但我们不能排除可能的混叠由于数据集的时间采样。此外，还发现了三个可能发生日食的候选天体(HD 15759、HD 120500和HD 149130)。否则，频率分析在我们严格的检测范围内显示为空结果。单个对象:HD 319, HD 6870 HD 7908, HD 11413, HD 13755, HD 15165, HD 15759, HD 23392, HD 24472, HD 30422, HD 31295, HD 35242, HD 64491, HD 74873, HD 75654, HD 81290, HD 83041, HD 83277, HD 84123, HD 84948, HD 87271, HD 91130, HD 101108, HD 102541, HD 105058, HD 106223, HD 107233, HD 110411, HD 111005, HD 111604, HD 111786, HD 120500, HD 120896, HD 125162, HD 130767, HD 141851, HD 142703, HD 149130, HD 153747, HD 154153, HD 156954, HD 160928, HD 168740, HD 170680, HD 171948, HD 175445, HD 183324,高清192640，高清198160，高清204041，高清210111，高清221756
Analysing the Hipparcos epoch photometry of γ Bootis stars
We performed a homogeneous analysis of the available Hipparcos epoch photometry for all members of the λBootis group. Besides the known δ Scuti like pulsation frequencies, we searched for eclipses due to binarity or rotational induced variability. The already known frequencies of HD 15165 are confirmed with an additional lower single frequency, which might be caused by an accretion episode. But we are not able to rule out a possible aliasing due to the temporal sampling of the data set. Furthermore, three candidates (HD 15759, HD 120500, and HD 149130) for a possible eclipse were detected. Otherwise, the frequency analysis reveals a null result within our strict detection limits. Individual Objects: HD 319, HD 6870, HD 7908, HD 11413, HD 13755, HD 15165, HD 15759, HD 23392, HD 24472, HD 30422, HD 31295, HD 35242, HD 64491, HD 74873, HD 75654, HD 81290, HD 83041, HD 83277, HD 84123, HD 84948, HD 87271, HD 91130, HD 101108, HD 102541, HD 105058, HD 106223, HD 107233, HD 110411, HD 111005, HD 111604, HD 111786, HD 120500, HD 120896, HD 125162, HD 130767, HD 141851, HD 142703, HD 149130, HD 153747, HD 154153, HD 156954, HD 160928, HD 168740, HD 170680, HD 171948, HD 175445, HD 183324, HD 192640, HD 198160, HD 204041, HD 210111, HD 221756
