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-0913175Reed这是一个探索性项目，用于对时间尺度小于十分钟的变异性进行有限调查。 通过获取已知包含变星的 40 个样本场的数据，这项初步研究将开发一个针对多个时间尺度内不同类型变异性的减少和分析管道，确定各种调查节奏的敏感性，寻找新类型的变异性，以及确定是否需要进行更大规模的调查。 主要目标是在不到一分钟的时间尺度上对天空进行采样，以确定是否存在迄今为止由于低时间采样而未被注意到的新现象。 该试验将确定检测短周期和长周期现象的最佳时间节奏，并提供将震级范围与检测极限相关联的准确统计数据，以优化曝光时间。 由于这项调查很可能会发现许多已知类型的新变星，因此了解设备和任何数据的时间和亮度变化限制非常重要。尽管这项研究将扩展我们对已知变星类型的物理特性的了解，最令人兴奋的前景是有机会发现新的、以前未知的现象。 此类调查自然会发现许多类型的主要恒星变异性，并且这些恒星的所有数据都可以在线获取，以便感兴趣的天文学家可以进行自己的研究。 本科生（由其他基金支持）将参与获取、减少和分析数据。 他们还将参与建立还原和分析程序，并与已知的变星进行关联。这将为他们提供非常全面的恒星天文学背景。这项工作由天文科学部的恒星天文学主题资助，作为探索性研究的小额资助。
