我们对一颗剑鱼座γ-盾牌座δ混合星星(KIC 6761539)的前三个夜晚的多色光度数据进行了初步分析,这颗恒星也被开普勒太空望远镜观测到。我们发现,多达四个(取决于滤波器)的最高振幅模式,其频率可以确定从开普勒数据,是从地面可见的。我们的目标是使用多色信息进行模式识别,但这只能在较长的时间序列中实现。为此,目前正在进行多色光度多站点活动(© 2012 WILEY‐VCH Verlag GmbH & Co. KGaA,魏因海姆)
We present a preliminary analysis of the first three nights of multi‐color photometric data for a γ Doradus‐δ Scuti hybrid star (KIC 6761539) that is also being observed with theKeplerspace telescope. We find that up to four (depending on the filter) of the highest amplitude modes, whose frequencies could be determined fromKeplerdata, are visible from the ground. Our goal is to use the multi‐color information for mode identification, but this will only be possible with a longer time series. A multi‐color photometric multi‐site campaign is currently ongoing for this purpose (© 2012 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
