摘要:

2009年3月成功发射的开普勒太空任务正在同时对数千颗恒星进行连续、高精度的测光。所有已知脉动类型的恒星不间断的时间序列是研究星震的宝贵资料。开普勒望远镜的数据没有提供关于物理参数的信息,如有效温度、表面重力、金属丰度和vsini,而这些参数对于成功地进行小行星地震建模至关重要。需要更多的地面时间序列数据来描述几种脉动星的模式参数。因此,需要地面多色测光和中/高分辨率光谱学来补充空间数据。我们目前的地面活动KASC内选定的几种脉动类型的开普勒目标的星震。(基于艾萨克·牛顿望远镜、威廉·赫歇尔望远镜、北欧光学望远镜、国家伽利略望远镜、墨卡托望远镜(西班牙拉帕尔马)和IAC-80(西班牙特内里费)的观测。也是根据内华达山脉、圣佩德罗马蒂尔、维也纳、兴隆、阿帕奇角、卢林、陶滕堡、洛亚诺、塞拉纳韦、阿西亚戈、麦克唐纳、斯基纳卡斯、南峰、莫纳克亚山、斯图尔特天文台、威尔逊山、弗罗茨瓦夫大学比亚科夫天文台、皮斯克斯泰托山站、上普罗旺斯天文台和卡拉阿尔托的西班牙阿莱曼天文中心的观测结果。数据来自AAVSO国际数据库。

英文摘要:

The Kepler space mission, successfully launched in March 2009, is providing continuous, high-precision photometry of thousands of stars simultaneously. The uninterrupted time-series of stars of all known pulsation types are a precious source for asteroseismic studies. The Kepler data do not provide information on the physical parameters, such as effective temperature, surface gravity, metallicity, and vsini, which are crucial for successful asteroseismic modelling. Additional ground-based time-series data are needed to characterize mode parameters in several types of pulsating stars. Therefore, ground-based multi-colour photometry and mid/high-resolution spectroscopy are needed to complement the space data. We present ground-based activities within KASC on selected asteroseismic Kepler targets of several pulsation types. (Based on observations made with the Isaac Newton Telescope, William Herschel Telescope, Nordic Optical Telescope, Telescopio Nazionale Galileo, Mercator Telescope (La Palma, Spain), and IAC-80 (Tenerife, Spain). Also based on observations taken at the observatories of Sierra Nevada, San Pedro Martir, Vienna, Xinglong, Apache Point, Lulin, Tautenburg, Loiano, Serra la Nave, Asiago, McDonald, Skinakas, Pic du Midi, Mauna Kea, Steward Observatory, Mt Wilson, Bialkow Observatory of the Wroclaw University, Piszkesteto Mountain Station, Observatoire de Haute Provence, and Centro Astronomico Hispano Aleman at Calar Alto. Based on data from the AAVSO International Database.)
