用开普勒一号探测恒星周期。选择目标的战略
Sounding stellar cycles with Kepler - I. Strategy for selecting targets
摘要：
开普勒卫星的长期监测和高光度精度将为利用星震学探测许多太阳型恒星的恒星周期提供一个独特的机会。这可以通过研究在这些恒星中观察到的振荡模式的振幅和频率的周期性变化来实现。通过将这些测量结果与传统的地面色球活动指数进行比较，我们可以更好地了解色球变化与整个恒星活动周期内部深处发生的变化之间的关系。此外，对流区深度和差异旋转的星震测量可以帮助我们确定恒星周期是在对流区的顶部还是底部驱动的。在本文中，我们分析的精度，将有可能使用开普勒测量恒星周期，对流区的深度，和微分旋转。基于这种分析，我们描述了一种策略，选择特定的目标观测开普勒天文地震调查的整个任务长度，以优化其适合探测恒星周期在各种各样的太阳型恒星。
英文摘要：
The long-term monitoring and high photometric precision of the Kepler satellite will provide a unique opportunity to sound the stellar cycles of many solar-type stars using asteroseismology. This can be achieved by studying periodic changes in the amplitudes and frequencies of the oscillation modes observed in these stars. By comparing these measurements with conventional ground-based chromospheric activity indices, we can improve our understanding of the relationship between chromospheric changes and those taking place deep in the interior throughout the stellar activity cycle. In addition, asteroseismic measurements of the convection zone depth and differential rotation may help us determine whether stellar cycles are driven at the top or at the base of the convection zone. In this paper, we analyze the precision that will be possible using Kepler to measure stellar cycles, convection zone depths, and differential rotation. Based on this analysis, we describe a strategy for selecting specific targets to be observed by the Kepler Asteroseismic Investigation for the full length of the mission, to optimize their suitability for probing stellar cycles in a wide variety of solar-type stars.
