0407260PI AlcockIn this research the investigators are developing a new, very fast camera system for very rapid, multi-object photometry, and are exploiting this new capability for new studies of extra-solar planet candidates using the transit technique. They will learn more about the prevalence of planets around other stars, and the relationship between our planetary system and other planetary systems. The signatures searched for are brief reductions in flux of field stars due to the transits by planets in orbit around these stars. There is a compelling need to photometer many stars as frequently as possible. For this reason, a major part of this program comprises the development of a novel CCD camera which can operate very quickly. The main goal of the camera effort is to have a camera based on one frame-transfer CCD that can monitor one star very quickly and with the exquisite precision of one part in 10,000 relative photometry. Broader impact. There is an international collaboration, which requires close working relationships with colleagues in Taiwan, South Korea, and Chile, exposing the students to the cultures of these nations, and allowing them to learn how to work in unfamiliar environments.

0407260PI Alcock在这项研究中，研究人员正在开发一种新的，非常快速的相机系统，用于非常快速的多目标测光，并利用这种新的能力，使用凌日技术对太阳系外行星候选者进行新的研究。 他们将更多地了解其他恒星周围行星的普遍性，以及我们的行星系统和其他行星系统之间的关系。 所寻找的特征是由于行星在这些恒星周围的轨道上过境而导致的场星通量的短暂减少。 迫切需要尽可能频繁地测量许多恒星的光度。 因此，该计划的主要部分包括开发一种新型CCD相机，这种相机可以非常快速地运行。照相机的主要目标是要有一个基于帧转移CCD的照相机，它可以非常快速地监视一颗星星，并具有万分之一的相对测光精度。更广泛的影响。有一项国际合作，需要与台湾、韩国和智利的同事建立密切的工作关系，让学生接触这些国家的文化，并让他们学习如何在陌生的环境中工作。
