AST-0913175ReedThis is an exploratory project for a limited survey for variability with time scales less than ten minutes. By obtaining data on 40 sample fields known to contain a variable star, this preliminary study will develop a reduction and analysis pipeline for variability of differing types over many time scales, determine the sensitivity of various survey cadences, search for new types of variability, and determine if a much larger survey is warranted. The main goal is to sample the sky on timescales less than one minute, to determine if new phenomena exist which have heretofore gone unnoticed because of low temporal sampling. This trial will determine the optimal temporal cadence to detect both short period and long period phenomena, and provide accurate statistics correlating magnitude range with detection limits so as to optimize exposure times. Since it is likely this survey will discover many new variable stars of known types, it is important to understand the temporal and brightness variation limits of the equipment and of any data.Although this study will extend our knowledge of the physical properties of known variable types, the most exciting prospect is the chance to uncover new, previously unknown phenomena. A survey of this sort will naturally uncover many types of mostly stellar variability, and all data for these stars will be available on-line, so that interested astronomers can perform their own studies. Undergraduate students (supported from other funds) will take part in obtaining, reducing, and analyzing the data. They will also be involved in establishing the reduction and analysis procedures and correlating with known variable stars. This will give them a very rounded background in stellar astronomy.This work is funded from the Stellar Astronomy theme of the Division of Astronomical Sciences, as a Small Grant for Exploratory Research.

AST-0913175REEDEEDTHIS是一个探索性项目，可进行有限的调查，可变可变性，时间尺度少于十分钟。 通过在已知包含可变恒星的40个样本字段上获得数据，这项初步研究将开发降低和分析管道，以了解许多时间尺度上不同类型的可变性，确定各种调查节奏的灵敏度，寻找新的可变性类型，并确定新型的变异性和确定是否有必要进行更大的调查。 主要目的是在不到一分钟的时间范围内采样天空，以确定是否存在新现象，而这些新现象是否由于时间抽样较低而无法引起人们的注意。 该试验将确定最佳的时间节奏，以检测短期和长期现象，并提供准确的统计数据将幅度范围与检测限制相关的统计数据，从而优化暴露时间。 由于该调查可能会发现许多已知类型的新变量星，因此了解设备和任何数据的时间和亮度变化极限很重要。尽管这项研究将扩展我们对已知变量类型的物理特性的了解，最令人兴奋的前景是发现新的，以前未知的现象。 对这种调查自然会发现许多类型的主要是恒星变异性，并且这些恒星的所有数据都将在线提供，以便感兴趣的天文学家可以进行自己的研究。 本科生（来自其他基金的支持）将参与获得，减少和分析数据。 他们还将参与建立还原和分析程序，并与已知的变量恒星相关。这将使他们在恒星天文学中具有非常圆润的背景。这项工作是根据天文学科学划分的恒星天文学主题来资助的，这是探索性研究的小赠款。
