光学和红外天文学中的高对比度观测

High-Contrast Observations in Optical and Infrared Astronomy

Ben R. Oppenheimer, Sasha Hinkley

摘要:

光学和红外天文学中的高对比度观测被定义为任何需要一种技术来揭示一个感兴趣的天体的观测,该天体与另一个光源的角度接近度至少为10^5倍,以至于光学效应阻碍或阻止直接从观测目标收集光子。这是一种相对较新的观测类型,可以研究宇宙中以前被遮蔽的部分。特别是,它是最适用于比较行星科学,一个领域,直接攻击这样的问题,如“如何共同的行星系统?存在什么类型的行星,除了地球之外,还有其他行星能够支持我们所知的生命吗?“我们调查了高对比度观测的科学动机,概述了目前正在使用或开发的技术,并讨论了未来前景的一些想法和研究。

英文摘要:

High-contrast observations in optical and infrared astronomy are defined as any observation requiring a technique to reveal a celestial object of interest that is in such close angular proximity to another source brighter by a factor of at least 10^5 that optical effects hinder or prevent the collection of photons directly from the target of observation. This is a relatively new type of observation that enables research on previously obscured parts of the Universe. In particular, it is most applicable to Comparative Planetary Science, a field that directly attacks such questions as "how common are planetary systems? What types of planets exist, and are there planets other than Earth that are capable of supporting life as we know it?" We survey the scientific motivations for high-contrast observations, provide an overview of the techniques currently being used or developed, and discuss some ideas and studies for future prospects.
